How to calculate pipeline velocity
WebOpen the bench valve and set the flow at the maximum flow in Part A (i.e., 17 liter/min); fully open the gate valve and flow control valve. Adjust the gate valve until 0.3 bar of head difference is achieved. Determine the volumetric flow rate. Repeat the experiment for 0.6 and 0.9 bars of pressure difference. 9.

The optimum water velocity in the pipe is from 0.6 m/s to 1.5 m/s (2-5 ft/s), the maximum is 3 m/s (10 ft/s). Note that you must enter the INNER diameter of the pipe, not the OUTSIDE. How do I estimate pipe diameter? Input the water velocity.

WebQ = Volumetric flowrate (m 3 /s) D = Pipe diameter (m) u = Fluid velocity in pipe (m/s) Note that the velocity will be constant for a non compressible fluid but will vary with a compressible fluid such as a gas. For a gas it is therefore necessary to slice the pipe layout in several sections in order to recalculate the velocity along the pipe.
WebIn order to calculate pipeline velocity, you can apply the same principle as calculating velocity in physics. In physics, velocity is the rate of change of position with respect to time.
