3.4        APPLICATION OF MOMENTUM Introduction The study of forces resulting from the impact of fluid jets and when fluids are diverted round pipe bends involves the application of newtons second law in the form of F = m.a. The forces are determined by calculating the change of momentum of the flowing fluids.    In nature these forces manifest themselves in the form of wind forces, and the impact forces of the sea on the harbour walls.   The operation of hydro-kinetic machines such as turbines depends on forces developed through changing the momentum of flowing fluids. I have created a excelcalcs spreadsheet for convenient access to all of the equations found on this page . This is located at  ExcelCalcs.com calculation Fluid Jets Symbols α = jet angle (radian) a = Acceleration (m/s  2 ) ρ = density (kg/m  3 ) ρ = density (kg/m  3 ) F = Force (N) ...

3.3 Measurement of velocity and discharge Defination Velocity : This refers to how quickly the water is moving. [Measured in feet per second (ft/s).] Discharge :   discharge refers to the water generated by the facility. It may be dewatering water, wash water, stormwater, or any combination of these. This term is comparable to “flow” which is used here in reference to receiving water flow. [Usually site discharge is measured in gallons per minute (gpm). Example Of Measurement Velocity Measurement with a Pitot Tube For pitot tube measurements and calculations, the reference plane is taken to be at the height of the pitot tube measurements, so the equation for stagnation pressure becomes: P stag  = P + ½ ρV 2  , which can be rearranged to: V = (2ΔP/ρ) 1/2 Where ΔP = P stag  – P. The pressure difference, Δp, (or P stag  – P), can be measured directly w...
