View Calculate Cfm From Psi And Pipe Size US. How to calculate the cfm and ratio the actual relationship between psi and cfm of the air compressor pump when it's refilling the the rule of thumb is you get about 4 cfm of compressed air at 90 psi for each hp of electric motor size.

PE, PEH or PVC Pipes - Pressure Drop Diagram from docs.engineeringtoolbox.com Cubic feet per minute (cfm) is the calculation of air volume velocity. This video goes into great detail on how to calculate cfm of dry airflow in a pipe using two different methods. Another input about calculating cfm from lukas:
Larger size piping increases air flow, but also increases the cost of your system.
Cfm stands for cubic feet per minute. A rule of thumb is to determine engine intake volume and then approximately match this volume for the exhaust. This example will calculate the flow rate of water draining from a tank through a pipe with cross sectional area of 0.500 square feet. To choose the correct diameter of pipe for your system, you need to know how much flow rate (cfm) will travel through the pipe and how long your piping will be.
