The aim of this note is to obtain a flow rate equation for subsonic Fanno flow, which has a form similar to the flow rate equation for isothermal flow. When pipe dimensions and the proper values of pressures and temperatures at two sections along a pipe, namely P-1, P-2, T-1 and T...
The article presents an equation which determines the key parameters of piping system design such as pipe diameter, volumetric flowrate and pressure drop. It features the Moody diagram which is used for f graphical approximation both under turbulent and laminar flows for rough and smooth pipes. It...
In a sense, the mass flow rate is the measure of the amount of fluid flowing through, say, a pipe, while the volumetric flow rate is the measure of 3D space occupied by the fluid that's passing through a pipe.Volume Flow Rate Equation Mass Flow Rate to Velocity Continuity Equation ...
Siphon Flow Rate: For ‘small diameter pipes’ friction losses in the pipe play a significant role and the head loss coefficient is estimated to equal: Symbols used: Q = Discharge (m3/s) Dp= Siphon internal diameter (m) g = Acceleration due to gravity (9.81 m/s2) ...
