2.2 Tutorial 1Creating a New ProjectData is entered and calculated in a worksheet. There are different worksheets fovarious structure types, because of the differing input and output data that is reqfor each.Tutorials

Bentley FlowMaster is an easy-to-use, Windows-based program that aids civil engi-neers with the design and analysis of pipes, ditches, open channels, weirs, and more.

Bentley FlowMaster computes flows, water velocities, depths and pressures based on several well-known formulas: Darcy-Weisbach, Mannings, Kutters, and Hazen-Will-iams. It also utilizes the HEC-22 methodology to perform pavement drainage and inlet flow calculations.

Bentley FlowMaster lets you solve for a variable you select, computing the solution from the parameters you provide. The program will also calculate rating tables, and will plot curves and cross sections. These graphs and reports can then be viewed on the screen, copied to the Windows clipboard, saved to a file, or printed on any stan-dard printer.

These tutorials provide step-by-step instructions for creating a project, entering data in a worksheet, and generating reports.

2.1 OverviewThe purpose of this section is to provide step-by-step tutorials to get you familiar with some of the features and capabilities of Bentley FlowMaster. The tutorials serve as a means to get you started exploring and using the software.

Note: You should follow these tutorials in sequence.

3.8.1 Rectangular Channel Dialog Boxes

The following controls make up the Rectangular Channel worksheet dialog box:

Solve ForThis drop-down list lets you select the variable that you are solving for. The variable that is chosen will appear yellow (read-only) in the list of avail-able input fields.

Friction MethodThis drop-down list lets you select the friction method that will be used to calculate the worksheet. The Darcy-Weisbach method requires an additional input variable (Kinematic Viscosity) and generates additional output (Friction Factor and Reynolds Number).

MessagesA Messages tab is included in each worksheet. The top section of this tab displays informational calculation messages, while the bottom section lets you enter any explanatory notes that you wish to be associated with the worksheet.

This dialog box comprises the following tabs:

Uniform Flow TabRectangular Channel

Gradually Varied Flow TabRectangular Channel

Uniform Flow TabRectangular Channel

The Uniform Flow tab comprises an input section on the left and an output, or results, section on the right.

Input:

Roughness CoefficientA value used to represent the resistance of a convey-ance element to flow.3-40 Bentley FlowMaster Users Guide


Channel SlopeLongitudinal slope in the channel. Also, the vertical drop

divided by the channel length.

Normal DepthDistance from water surface to low point of channel bottom.

Bottom WidthWidth of the bottom of the channel cross section.

DischargeVolumetric rate of flow, given in units of length (cubed) over time.

Kinematic Viscosity (This input is only available when one of the Darcy-Weis-bach Friction methods is used)Viscosity divided by the mass density given in units of length (squared) over time, hence the term kinematic. Viscosity is a prop-erty measuring the fluid resistance to shear. For example, molasses and tar have relatively high viscosity and water and air relatively low viscosity.

Output:

Flow AreaCross-sectional area of flow.

Wetted PerimeterPerimeter of flow that travels against a solid boundary. For a partially full pipe, the wetted perimeter includes all of the flow perimeter except for the top segment, which has a free surface.

Top WidthLength of the free top surface on the flowing cross section. For a cross section flowing full, this value is zero.

Critical DepthDepth of water in the channel for which the specific energy is at its minimum. Specific Energy is the sum of the elevation head and velocity head (energy due to the velocity of a liquid) as related to the section of a channel bed.

Critical SlopeChannel slope for which the uniform flow (equilibrium flow for which the slope of total energy equals the channel slope) is critical.

VelocityLinear measure of flow rate given in units of length over time. For weirs and orifices, the velocity field is for the velocity of the water through the hydraulic structure.

Velocity HeadEnergy due to the velocity of a liquid.

Specific EnergySum of the elevation head and velocity head (energy due to the velocity of a liquid) as related to the section of a channel bed.

Froude NumberDimensionless parameter used to characterize open channel flow. For critical flow, this value is 1.

Flow TypeThe flow is defined as:

Supercritical if F > 1

Subcritical if F < 1

Critical if F = 1

where F is the Froude Number.Bentley FlowMaster Users Guide 3-41

Friction Factor (This output is only available when one of the Darcy-Weisbach

Friction methods is used)Friction coefficient used in the Darcy-Weisbach (Colebrook-White) Formula.

Reynolds Number (This output is only available when one of the Darcy-Weis-bach Friction methods is used)Ratio of viscous forces relative to inertial forces.

Gradually Varied Flow TabRectangular Channel

The Gradually Varied Flow tab comprises an input section on the left and an output, or results, section on the right. There is also a Direction drop-down list:

DirectionThis drop-down list lets you choose whether you are solving for the Upstream Depth or the Downstream Depth, as follows:

Given UpstreamWhen you choose this option, the Upstream Depth is an input variable and the gradually varied flow analysis will solve for down-stream depth.

Given DownstreamWhen you choose this option, the Downstream Depth is an input variable and the gradually varied flow analysis will solve for upstream depth.

Input:

Downstream DepthDistance from water surface to low point of channel bottom at the downstream end of the channel.

Upstream DepthDistance from water surface to low point of channel bottom at the upstream end of the channel.

LengthThe length of the channel.

Number of StepsThe number of segments per profile that the channel is divided into based on its starting and goal depth. In unbounded cases, the number of
