## Power Flowrate Temp Calculator

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

## Temperature Conversion Calculator

°F = ( ( ( °C * 9) / 5 ) + 32 )

°C = ( ( ( °F - 32) * 5 ) / 9 )

Fill in one value to calculate the other

## Three Phase Unit Calculator

Line Current = Wattage / (Voltage * v3)

Fill in two values to determine the third

## Single Phase Unit Calculator

Line Current = Wattage / Voltage

Fill in two values to determine the third

## Ohms Law Calculator

Fill in two values to determine the other two

## Heat Transfer Through Convection Calculator

- ρ = density (lb/ft
^{3}) - V = volume flow rate (ft
^{3}/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 to SCFM Calculator

- 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 to Volumetric Flow Calculator

Mass flow rate to Volumetric flow rate for air

Fill in one value to calculate the other two
