Welcome to the engineering calculators resource page. Below you will find several useful calculators to help you quickly compute common calculations. These calculators can also be found in the sidebox area of relevant product pages. If there is a common calculation you perform that isn't found here, feel free to send us a message, and we may develop it!
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.
Single Phase Unit
Line Current= Wattage / Voltage
Three Phase Unit
Line Current = Wattage / (Voltage * √3)
°F = ( ( ( °C * 9) / 5 ) + 32 )
°C = ( ( ( °F - 32) * 5 ) / 9 )
Calculate the heat flux, temperature requirement, or volume as follows:
ρ = density (lb/ft3)
V = volume flow rate (ft3/hour)
Cp = specific heat (Btu/lb°F)
Ta-Tb = temperature differential (°F)
Q = ρ x V x Cp x (Ta-Tb)
Fill in four values to determine the fifth.
