CFM (Cubic Feet per Minute) is a unit of measurement used to express the flow rate of a gas or air. It is commonly used to measure the volume of air moved by equipment such as compressors, blowers, and air conditioning systems.
CFM represents the volume of gas or air, in cubic feet, that passes through a system in one minute under given conditions of pressure and temperature.
When designing systems involving air or gas flow, it is important to know the required CFM to ensure proper operation of equipment. To convert CFM to SCFM (Standard Cubic Feet per Minute), you need to account for temperature, pressure, and humidity variations.
To calculate the SCFM, you need to know the CFM, actual temperature, actual pressure, barometric pressure, and relative humidity. The formula is:
SCFM = CFM × \(\frac{P_b - (RH_a \times P_{va})}{P_s - (RH_s \times P_{vs})} \times \frac{T_s}{T_a} \times \frac{P_a}{P_b}\)
Use the form above to input the values, and the calculator will provide the required SCFM.
