WebbThe pipe flow calculator can be used in the following way. Step 1: In the unknown value input area, enter the velocity, pipe diameter, and x. Step 2: To obtain the flow rate, click … WebbFlow in Pipes Running Full. The Colebrook White equation calculates the velocity ( v) of flow through a circular pipe running full using the below equation; This is the acceleration due to gravity, typically taken as 9.81m/s 2 at sea level. This is the internal diameter of the pipe being considered. This is effectively the slope of pipe in m/m.
WebbPump Head = 0 if no pump present. The pressure drop or rather pressure difference dP (it could be a gain) between the start and the end of a pipe is therefore given by this equation: dP = Friction Loss + Fittings Loss + … Webb2.The flow entering a jun ction must be equal to the flow leaving that junction; i.e. the law of cont inuity must be satisfied.
