Use the Excel formulas in the templates included with this article to compute the hydraulic portion for storm water drainage in a storm sewer design.
Hydraulics in Civil Engineering
Hydraulics is an important field in Civil Engineering that has to do with the mechanical properties of liquids. Whether the project is a tunnel, road or series of pipes running through a building, it’s important to know how the water will travel and what conditions the building will be safe under. Read more about topics like fluid mechanics, fluid machinery, irrigation, coastal waters and more.
Find help calculating normal depth for uniform open channel flow with the downloadable templates available in this article. We use iterative Manning equation calculations to determine the normal depth of flow that will take place for a given flow rate, in a channel of known bottom slope, size, shape, and roughness.
The Excel spreadsheet templates provided in this article will help you make open channel flow measurement calculations for water flow rate over a V notch weir. Formulas are given for the simple calculations of a 90 degree V notch weir and the more complicated calculations for a non 90 degree notch angle.
Calculation of frictional head loss or pressure drop for pipe flow, using the Darcy Weisbach/ friction factor equation, can be done with downloadable Excel spreadsheet templates given in this article. A template is also given for calculation of pipe diameter needed for given flow rate and head loss.
There have been numerous government enquiries and subsequent reports over the last century into the construction of a tidal barrage across the River Severn Estuary linking England to Wales.
None have come to fruition due to economic and environmental concerns and, the sheer magnitude of the project
Determining Manning roughness coefficient, n, for use in the Manning equation, is a key step in open channel flow calculations for water flow in a natural channel. Determining the Manning roughness coefficient, n, for a natural channel is difficult due to the variability of channel surfaces.
A reaction water turbine is used where the water supplied from the dam is of low head combined with a high flow quantity. There are two types of reaction turbines used in hydrokinetics; propeller and radial turbines. Both types are enclosed in a casing similar in shape to that of a centrifugal pump.
