Get A QuoteBoiler Piping Flow & Pipe Sizing - Flow Rate Calculation To achieve calculated flow rate when sizing the pump use the following formula: Take the measurement of the longest run in the loop in feet and add 50% to that measurement. Multiply that number by.04 to get the pump head.

Get A QuoteUsing 15 mm dia pipe, the requirement of 519 litres/hours gives a flow of 154 cm/second (i.e. 148 * (519/500)) - this exceeds the maximum of 90 cm/second so 15 mm pipe is not suitable. Using 22 mm dia pipe, the same total flow requires a flow of 57 cm/second (i.e. 55* (519/500)) - this is well within the maximum speed so 22 mm dia pipe can be used.
