HYDRAULICS AND HYDROLOGY Level 6
TUTORIAL 3 - PUMP THEORY This unit has two outcomes. Outcome 2 is on hydrological cycles and is not covered in this set of
tutorials. Outcome 1 is a large outcome and some parts are not covered fully. You will find other material
of use to your studies under Fluid Mechanics Unit 129

b velocity distributions.
c laminar and turbulent flows in smooth
and rough pipes
d Poiseuille’s law
e Darcy’s law
5. Examine the relationship between friction
factor, Reynolds number and relative
roughness.
6. Examine local losses in pipe systems due
to friction.
7. Analyse pipe networks using Hardy Cross
method and Garnish method.
8. Determine the reasons for unsteady pipe
flow in respect of:

12. Select a pump for a range of pipe
systems.
13. Assess steady flow in an open channel
using Chezy and Manning equations.
14. Design non-erodible channels.
15. Recognise the effect of sediment
transportation in open channels.
16. Analyse gradual varied non-uniform
flow in channels
