1.6 PHILOSOPHY
Our work to verify the pump capacity and head are sufficient to
supply the site and meet the minimum requirement by NFPA or
not.
The calculation is three stage:
o To check the given capacity and head of the pump with the
remotest area of the Operation Area.
o To check the given capacity and head of the pump with the
remotest landing valve.
Sequence of hydraulic calculations:
o Sprinkler and fire hose cabinet:
Inside Hose stream allow will be 100 gpm (as per item Table
11.2.3.1.2 Hose Stream Allowance and Water Supply Duration
Requirements for Hydraulically Calculated Systems page 13-123, NFPA
13, 2013 Edition).
Determine the remotest operation area which located in the Roof
floor (mechanical room) of work shop building.
Determine the hazard of the operation area (Ordinary Hazard as
per item A.5.5 page 13-266 NFPA 13-2013 Edition).
Default K Factor of sprinkler will be 5.65 gpm/psi^ (Selected
for Light Hazard).
Minimum Desired Density will be 0.1 gpm/ft (as per item 11.2.3
page 13-122 NFPA 13-2013 Edition).
Sprinkler system type will be wet system.
Max area per sprinkler will be 130 ft (as per Table 8.6.2.2.1(a)
Protection Areas and Maximum Spacing of Standard Pendent and
Upright Spray Sprinklers for Ordinary Hazard page 13-35 NFPA13,
2013Edition).

MBXX (PA) R.H. A.S June - 2014
The number of calculated sprinklers will be 11 sprinklers (as
per FIGURE A.23.4.4 Example of Determining the Number of Sprinklers
to be calculated. page 13-395 NFPA 13, 2013 Edition) )(this number
of sprinkler may be increase according to architectural drawing to
cover selected area from Density/area curve)
Design area will be 1500 ft (as per item 11.2.3 page 13-122 NFPA
13-2013 Edition, Find attached file).
Area per sprinkler will be 13.77949 ft * 942.8.9 ft = 136 ft.
Total Sprinkler to Calculate = 1500 / 136 = 11 sprinklers. Number
of sprinklers on branch line = (1.2 1500)/14 = 3
sprinklers. o Landing Valve Calculation:
Class of hose is I (as per item 7.3.2 Class I Systems page 14-18
NFPA 14, 2013 Edition).
Residual Pressure for Class I will be 100 psi (6.9 par) (as per
item 7.8.1 Minimum Design Pressure for Hydraulically Designed
Systems page 14-19 NFPA 14, 2013 Edition).
Flow will be 250 gpm (as per item 7.10.1.2 Hydraulic Calculation
Requirements page 14-20 NFPA 14, 2013 Edition).
Calculated K-Factor Will be as per formula (K=Q/P) where Q is
Flow of the landing valve (250 gpm) and P is the Pressure (100 PSI)
So the K=250100 = 25 (as per item 23.4.2.5 K-Factor Formula page
13-236 NFPA13, 2013 Edition).
Type Of hydraulic calculation methods:
o Demand Mode (I need to put the minimum residual pressure at
remotest area, if Sprinkler will be 15 PSI as per Table 11.2.2.1
Water Supply Requirements for Pipe Schedule Sprinkler Systems page
13-122 NFPA13, 2013 Edition) and minimum density as per item 11.2.3
page 13-122 NFPA 13-2013 Edition).
o Supply Mode (if we have given Flow and Pressure)

11.2.1 General.
11.2.1.1* The water demand requirements shall be determinedby
either the pipe schedule method in accordance with 11.2.2 orthe
hydraulic calculation method in accordance with 11.2.3.
11.2.1.2 Occupancy Classifications.
11.2.1.2.1 Occupancy classifications for this standard shall
re-late to sprinkler installations and their water supplies
only.
11.2.1.2.2 Occupancy classifications shall not be used as
ageneral classification of occupancy hazards.
11.2.1.2.3 Occupancies or portions of occupancies shall
beclassified according to the quantity and combustibility of
con-tents, the expected rates of heat release, the total potential
forenergy release, the heights of stockpiles, and the presence
offlammable and combustible liquids, using the definitions
con-tained in Section 5.2 through Section 5.5.
11.2.1.2.4 Classifications shall be as follows:
(1) Light hazard(2) Ordinary hazard (Groups 1 and 2)(3) Extra
hazard (Groups 1 and 2)(4) Special occupancy hazard (see Chapter
22)
11.2.2 Water Demand Requirements Pipe Schedule Method.
11.2.2.1 Table 11.2.2.1 shall be used in determining the
mini-mum water supply requirements for light and ordinary
hazardoccupancies protected by systems with pipe sized according
tothe pipe schedules of Section 23.5.
11.2.2.2 Pressure and flow requirements for extra hazard
oc-cupancies shall be based on the hydraulic calculationmethodsof
11.2.3.
11.2.2.3 The pipe schedule method shall be permitted as
fol-lows:
(1) Additions or modifications to existing pipe schedule
sys-tems sized according to the pipe schedules of Section 23.5
(2) Additions or modifications to existing extra hazard
pipeschedule systems
(3) New systems of 5000 ft2 (465 m2) or less(4) New systems
exceeding 5000 ft2 (465 m2) where the flows
required in Table 11.2.2.1 are available at a minimum re-sidual
pressure of 50 psi (3.4 bar) at the highest elevationof
sprinkler
11.2.2.4 Table 11.2.2.1 shall be used in determining the
mini-mum water supply requirements.
11.2.2.5 The lower duration value of Table 11.2.2.1 shall
beacceptable only where the sprinkler system waterflow
alarmdevice(s) and supervisory device(s) are electrically
supervisedand such supervision is monitored at an approved,
constantlyattended location.
11.2.2.6* Residual Pressure.
11.2.2.6.1 The residual pressure requirement of Table
11.2.2.1shall be met at the elevation of the highest sprinkler.
11.2.2.6.2 Friction Loss Due to Backflow Prevention Valves.
11.2.2.6.2.1 When backflow prevention valves are installedon
pipe schedule systems, the friction losses of the device shallbe
accounted for when determining acceptable residual pres-sure at the
top level of sprinklers.
11.2.2.6.2.2 The friction loss of this device [in psi (bar)]
shallbe added to the elevation loss and the residual pressure at
thetop row of sprinklers to determine the total pressure neededat
the water supply.
11.2.2.7 The lower flow figure of Table 11.2.2.1 shall be
permit-ted only where the building is of noncombustible
construction orthe potential areas of fire are limited by building

23.4 Hydraulic Calculation Procedures.
23.4.1* General.
23.4.1.1 A calculated system for a building, or a
calculatedaddition to a system in an existing sprinklered building,
shallsupersede the rules in this standard governing pipe
schedules,except that all systems shall continue to be limited by
area.
23.4.1.2 Pipe sizes shall be no less than 1 in. (25 mm) nomi-nal
for ferrous piping and 34 in. (20 mm) nominal for coppertubing or
nonmetallic piping listed for fire sprinkler service.
23.4.1.3 The size of pipe, number of sprinklers per branchline,
and number of branch lines per cross main shall other-wise be
limited only by the available water supply.
23.4.1.4 However, sprinkler spacing and all other rules cov-ered
in this and other applicable standards shall be observed.
23.4.1.5 Hydraulic calculations shall extend to the
effectivepoint of the water supply where the characteristics of the
watersupply are known.
23.4.2 Formulas.
23.4.2.1 Friction Loss Formula.
23.4.2.1.1 Pipe friction losses shall be determined on the
ba-sis of the HazenWilliams formula, as follows:
pQ
C d=
4 52 1 851 85 4 87
. .. .
where:p = frictional resistance (psi/ft of pipe)Q = flow (gpm)C
= friction loss coefficientd = actual internal diameter of pipe
(in.)
23.4.2.1.2 For SI units, the following equation shall be
used:
pQ
C dmm

Subsection 23.4.2.1.3 was revised by atentative interim
amendment (TIA). Seepage 1.
23.4.2.1.3 For antifreeze systems greater than 40 gal (151 L)in
size, the friction loss shall also be calculated using
theDarcyWeisbach formula:
= P f l Qd

where:P = friction loss (psi)
f = friction loss factor from Moody diagraml = length of pipe or
tube (ft)
= density of fluid (lb/ft3)Q = flow in pipe or tube (gpm)d =
inside diameter of tube (in.)
23.4.2.2 Velocity Pressure Formula. Velocity pressure shall
bedetermined on the basis of the following formula:
PQ
Dv=
0 001123 24
.
where:Pv = velocity pressure (psi) (SI, 1 psi = 0.0689 bar)Q =
flow (gpm) (SI, 1 gal = 3.785 L)D = inside diameter (in.) (SI, 1
in. = 25.4 mm)
23.4.2.3 Normal Pressure Formula. Normal pressure (Pn)shall be
determined on the basis of the following formula:
P P Pn t v=
where:Pn = normal pressurePt = total pressure [psi (bar)]Pv =
velocity pressure [psi (bar)]
23.4.2.4 Hydraulic Junction Points.
23.4.2.4.1 Pressures at hydraulic junction points shall bal-ance
within 0.5 psi (0.03 bar).
23.4.2.4.2 The highest pressure at the junction point, andthe
total flows as adjusted, shall be carried into the
calcula-tions.
23.4.2.4.3 Pressure balancing shall be permitted through theuse
of a K-factor developed for branch lines or portions ofsystems
using the formula in 23.4.2.5.
23.4.2.5 K-Factor Formula. K-factors, flow from an orifice,
orpressure from an orifice shall be determined on the basis ofthe
following formula:
KQPn
=
where:Kn = equivalent K at a nodeQ = flow at the nodeP =
pressure at the node
23.4.3 Equivalent Pipe Lengths of Valves and Fittings.
23.4.3.1 Pipe and Fittings.
23.4.3.1.1 Table 23.4.3.1.1 shall be used to determine
theequivalent length of pipe for fittings and devices unless
manu-facturers test data indicate that other factors are
appropriate.
23.4.3.1.2 For saddle-type fittings having friction loss
greaterthan that shown in Table 23.4.3.1.1, the increased friction
lossshall be included in hydraulic calculations.
23.4.3.1.3 Equivalent Length Modifier.
23.4.3.1.3.1 For internal pipe diameters different fromSchedule
40 steel pipe [Schedule 30 for pipe diameters 8 in.(200 mm) and
larger], the equivalent length shown in Table23.4.3.1.1 shall be
multiplied by a factor derived from the fol-lowing formula:
Actual inside diameterSchedule 40 steel pipe inside
diameteer
Factor
=
4 87.
23.4.3.1.3.2 The factor thus obtained shall be further modi-fied
as required by Table 23.4.3.1.1. This table shall apply toother
types of pipe listed in Table 23.4.3.1.1 only where modi-fied by
factors from 23.4.3.1.1 and 23.4.3.2.

A.4.4 Biocides and other chemicals that are approved andused for
the prevention and mitigation of MIC and that do notadversely
affect the fire-fighting properties of the water or theperformance
of the fire sprinkler system components are notprohibited.
A.4.6 Non-system components can adversely affect the opera-tion
and longevity of the fire sprinkler system.Objects connectedto the
sprinkler system can displace sprinkler systempiping, caus-ing
obstruction to the spray pattern of sprinklers, delay the
acti-vation of a sprinkler, or cause chemical compatibility
problemsthat can cause the failure of sprinkler system
components.
A.5.1 Occupancy examples in the listings as shown in thevarious
hazard classifications are intended to represent thenorm for those
occupancy types. Unusual or abnormal fuelloadings or combustible
characteristics and susceptibility forchanges in these
characteristics, for a particular occupancy,are considerations that
should be weighed in the selection andclassification.
The light hazard classification is intended to
encompassresidential occupancies; however, this is not intended to
pre-clude the use of listed residential sprinklers in residential
oc-cupancies or residential portions of other occupancies.
A.5.2 Light hazard occupancies include occupancies havinguses
and conditions similar to the following:
(1) Animal shelters(2) Churches(3) Clubs(4) Eaves and overhangs,
if of combustible construction with
no combustibles beneath(5) Educational(6) Hospitals, including
animal hospitals and veterinary fa-
cilities(7) Institutional(8) Kennels(9) Libraries, except large
stack rooms
(10) Museums(11) Nursing or convalescent homes(12) Offices,
including data processing(13) Residential(14) Restaurant seating
areas(15) Theaters and auditoriums, excluding stages and
prosce-
niums(16) Unused attics
Note that it is not the committees intent to automaticallyequate
library bookshelves with ordinary hazard occupancies orwith library
stacks. Typical library bookshelves of approximately8 ft (2.4 m) in
height, containing books stored vertically on end,held in place in
close association with each other, with aisleswider than 30 in.
(762 mm) can be considered to be light hazardoccupancies.
Similarly, library stack areas, which aremore akin toshelf storage
or record storage, as defined in NFPA 232, shouldbe considered to
be ordinary hazard occupancies.

A.5.3 For purposes of these definitions, Class I, Class II,
ClassIII, and Class IV commodities would be considered to
havemoderate rates of heat release, while Group A plastics wouldbe
considered to have high rates of heat release. Stockpiles
areconsidered to include display merchandise (mercantile)

products(6) Distilleries(7) Dry cleaners(8) Exterior loading docks
(Note that exterior loading docks
only used for loading and unloading of ordinary combus-tibles
should be classified as OH2. For the handling offlammable and

coating(4) Manufactured home or modular building assemblies
(where finished enclosure is present and has combus-tible
interiors)
(5) Open oil quenching(6) Plastics manufacturing(7) Solvent
cleaning(8) Varnish and paint dipping
A.5.5 Other NFPA standards contain design criteria for
firecontrol or fire suppression (see Section 5.5 and Chapter 2).
Whilethese can form the basis of design criteria, this standard
de-scribes the methods of design, installation, fabrication,
calcu-lation, and evaluation of water supplies that should be used
forthe specific design of the system.
Other NFPA standards contain sprinkler system design cri-teria
for fire control or suppression of specific hazards.
Thisinformation has been either referenced or copied into Chap-ter
22 using NFPAs extract policy.
A.5.6 Specification of the type, amount, and arrangement
ofcombustibles for any commodity classification is essentially
anattempt to define the potential fire severity, based on its
burningcharacteristics, so the fire can be successfully controlled
by theprescribed sprinkler protection for the commodity class. In
ac-tual storage situations, however, many storage arrays do not
fitprecisely into one of the fundamental classifications;
therefore,the user needs to make judgments after comparing each
classifi-cation to the existing storage conditions. Storage arrays
consist ofthousands of products, whichmake it impossible to specify
all theacceptable variations for any class. As an alternative, a
variety ofcommon products are classified in this annex based on
judg-ment, loss experience, and fire test results.
Table A.5.6 provides examples of commodities not ad-dressed by
the classifications in Section 5.6.
Table A.5.6.3 is an alphabetized list of commodities
withcorresponding classifications.
Table A.5.6.3.1 through Table A.5.6.3.4 and Table
A.5.6.4.1provide examples of commodities within a specific
class.
A.5.6.1.1 Commodity classification is governed by the typesand
amounts of materials (e.g., metal, paper, wood, plastics)that are a
part of a product and its primary packaging. How-ever, in a storage
or warehousing situation, classification is alsoaffected by such
factors as the primary storage or shippingcontainer material, the
amount of air space, and the location
