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.
Circular pipe culverts are widely used in building projects. Do you know the equations that relate pipe culvert parameters under the condition of inlet control, or outlet control? Learn the equations in this article.
The widespread applications of fluid mechanics and hydraulics in civil engineering include transportation of fluids in pipes and in open channels, as well as flow measurement for both pipes and open channels. These areas of application use a variety of calculations for design and for analysis.
Calculation of critical slope and critical depth for open channel flow is needed for some applications. Read on for the equations, calculation procedures, and examples for a rectangular channel and for a trapezoidal channel.
The St Francis Dam failure in California occurred in 1928, two short years after its completion, resulting in over 450 deaths. The dam was constructed of concrete in an arch-gravity design, and spanned the San Francisquito Canyon forming a reservoir that supplied Los Angeles with drinking water.
Do you want to invest in household water treatment systems? Are you puzzled with regard to the system you should install? Perform a comparison of household water treatment systems before you install one. Do you need: carbon filter, reverse osmosis system, water softener, and ultraviolet system?
Heightened public awareness and stricter application of effluent standards by the authorities has led to industrial wastewater reuse being given a lot of importance. Advanced technologies have also led to such reuse becoming feasible and economical.
Pipes are laid in the ground and soil conditions that are acidic can cause water mains to corrode and rupture. Breaks can also be occur when the pipes are subjected to very high pressures, which can even come from the water hammer cause by incorrect closing of valves.
We have been using rivers to power the turbine of low head hydropower schemes for some time. However, there has been an innovative small hydropower design under test at Technische Universitat Munchen in Germany that uses very low heads. The complete unit is integral and concealed in a shaft.
Download Excel spreadsheet templates for storm water runoff control structure design in U.S. units or S.I. units, to be used with storm water retention or detention ponds. The control structure will reduce the detention pond discharge to the pre-development, watershed peak storm water runoff rate.
The Excel spreadsheets that can be downloaded from this article use Excel formulas to calculate the volume needed for storm water retention or detention ponds. Parameters needed in the equations include, watershed time of concentration and peak storm water runoff rate.
Broad crested weir flow rate calculations can be made with the Excel spreadsheets that can be downloaded from this article. The open channel flow rate can be found using a broad crested weir equation for critical flow over the weir, along with the minimum weir height needed for critical flow.
Download spreadsheets with Excel formulas to make Parshall flume open channel flow measurement calculations. These have been built into the Excel spreadsheets for free flow and submerged flow with U.S. units or S.I. units.
Get Excel spreadsheet templates for calculating a watershed time of concentration. This parameter is of interest primarily for its use to calculate peak storm water runoff rate for storm water management facilities.
Rational method runoff coefficient tables are provided in this article. Watershed runoff coefficients depend upon the land use, soil type and slope of the watershed. Runoff coefficients are needed to calculate storm water runoff rate using the Rational Method.
Download Excel spreadsheets to calculate design rainfall intensity and design peak storm water runoff rate. The Excel formulas derive an equation for rainfall intensity and then calculate the design values in either U.S. units or S.I. units.
Make open channel flow calculations for partially full pipe flow with these excel spreadsheet templates. We use the Manning equation and equations for partially full pipe flow to calculate flow rate and velocity or normal depth
