Reference Data

 

Air Heater Energy Requirement:

kW = SCFM x (Texit – Tinlet) / 2500

________________________________________

Temperature Conversions:

°F = 9/5 (°C) + 32
°C = 5/9 (°F – 32)
________________________________________

Air Flow Conversions:

SCFM = SCFH / 60 = SLPM / 28.3
SLPM = SCFH / 2.12
SCMH = SCFH / 35.3
SCFM = (Pounds of Air Per Minute) / (.080 lbs/ft3)

SCFM = Standard Cubic Feet per Minute
SCFH = Standard Cubic Feet per Hour
SLPM = Standard Liters per Minute
SCMH = Standard Cubic Meters per Hour





 

 

 

 

Wye Configuration

________________________________________

Single Phase Wiring:

V = I x R (Volts = Amps x Ohms)
I = W / V (Amps = Watts / Volts)
W = V2/R (Watts = (Volts x Volts) / Ohms)
________________________________________

Three Phase Wiring:

Delta Configuration:

R = R1 = R2 = R3
Wdelta = 3(VL2)/R
Wdelta = 1.73 x VL x IL
IP = IL/1.73
VP = VL

Wye Configuration:

R = R1 = R2 = R3
Wwye = (VL2)/R = 3(VP2)/R
Wwye = 1.73 x VL x IP
IP = IL
VP = VL/1.73
