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...

Basic Equation In Fluid Mechanics Introduction  Fluid mechanics considerations are applied in many fields, especially in engineering. Below a list is provided which clearly indicates the far-reaching applications of fluid-mechanics knowledge and their importance in various fields of engineering. Whereas it was usual in the past to carry out special fluid mechanics considerations for each of the areas listed below, today one strives increasingly at the development and introduction of generalized approaches that are applicable without restrictions to all of these fields. This makes it necessary to derive the basic equations of fluid mechanics so generally that they fulfill the requirements for the broadest applicability in areas of science and engineering, i.e. in those areas indicated in the list below. The objective of the derivations in this section is to formulate the conservation laws for mass, momentum, energy, chemical species, etc., in such a way that they can be app...
