°F = (1.8 x °C) + 32
°C = (°F - 32) / 1.8

Line Current = Wattage / (Voltage * √3)

Line Current = Wattage / Voltage

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

• 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)

• 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
