With our Flow Calculator you determine the flow velocity, the flow rate and the pressure loss in relation to the internal pipe diameter and nominal diameter.
The flow velocity must be approximated according to the intended use of the pipeline.
Standard values for the flow velocity are:
v = 0.5 - 1.0 m/s for the suction side
v = 1.0 - 3.0 m/s for the pressure side
To find the outside diameter using the inside diameter and the applicable SDR, use the following formula:
