ELECTRICAL / MECHANICAL APPLICATION FORMULAS
Power - AC Circuits, Power - DC Circuits, Mechanical, Fans & Blowers, Pump Motors
OHMS LAW
Volts (E) = Amps (I) x Ohms (R)
Amps (I) = Volts (E) / Ohms (R)
Ohms (R) = Volts (E) / Amps (I)
R=Ohms, E=Volts, I=Amperes
POWER - AC CIRCUITS
Eff. = Efficiency, PF = Power Factor, KW = Kilowatts, HP = Horsepower
Efficiency =
746 x Output HP
Input Watts

HP =
Volts x Amps x Eff.

MECHANICAL
Torque in lb. ft., RPM=Revolutions Per Minute, HP = Horsepower
Torque =
HP x 5250
RPM
Result is lb.ft. Multiply by 12 for lb.in.
HP =
Torque X RPM
5250
1 HP = 36 lb.in. @ 1750 RPM 1 HP = 3 lb. ft. @ 1750 RPM
FAN AND BLOWER MOTORS
CPM = Cubic Feet per Minute, Pressure in lb. / sg. ft., Eff. = Efficiency
HP =
CFM x Pressure
33000 x Eff.
