Q = ρ x V x Cp x (Ta-Tb)


Fill in four values

ρ = density (lb/ft3)
V = volume flow rate (ft3/hour)
Cp = specific heat (Btu/lb°F)
Ta-Tb = TD (°F)
Q = ρ x V x Cp x (Ta-Tb)

ACFM to SCFM

ACFM = airflow in actual cubic feet per minute

P = gage pressure (psi)

T = gas temperature °R = 460 + °F

SCFM = airflow in standard cubic feet per minute


Find Standard Cubic Feet per Minute based on data from your Actual Cubic Feet per Minute Rotameter

airflow in actual cubic feet per minute
gage pressure (psi)
gas temperature °R = 460 + °F
airflow in standard cubic feet per minute

Standard Flow Rate (SCFM) Calculator

Calculate the SCFM.
Actual cubic feet per minute
Actual pounds per square inch at Gauge
Actual temperature in °F. °R = 460 + °F
CFM * (PSI actual / 14.7psi)*(528°R / T actual)

Pressure Conversion

Fill in one value to calculate the other.
PSI = Bar * 14.504
Bar = PSI / 14.504

Mass Flow to volume Metric Flow

Fill in one value to calculate the other two
Kg/h = Kilogram Per Hour (lb/min multiply by 27.216)
Lbs/min = Pounds per minute (kg/h divide by 27.216)
SCFM = Standard cubic feet per minute
