Calculate the electrical power, flow rate or temperature requirement as follows:

• SCFM = airflow in standard cubic feet per minute
• ΔT = temperature rise in degrees F from the inlet to the exhaust
• Watts = SCFM x ΔT/3

Fill in two values to determine the third

°F = ( ( ( °C * 9) / 5 ) + 32 )
°C = ( ( ( °F - 32) * 5 ) / 9 )

Fill in one value to calculate the other

Line Current = Wattage / (Voltage * v3)

Fill in two values to determine the third

Line Current = Wattage / Voltage

Fill in two values to determine the third

Fill in two values to determine the other two

• ρ = density (lb/ft³)
• V = volume flow rate (ft³/hour)
• Cp = specific heat (Btu/lb°F)
• T_a-T_b = temperature differential (°F)
• Q = ρ x V x Cp x (T_a-T_b)

Fill in four values to determine the fifth

• 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

Fill in 3 values to determine the SCFM

Mass flow rate to Volumetric flow rate for air

Fill in one value to calculate the other two
