Calculate Velocity From RPM

Velocity From RPM = 0.262DiameterRPM*Velocity

Calculate Velocity from HP & Force

Velocity from HP & Force = HP X 33000 / Force Lbs

Calculate RPM from Velocity

RPM from Velocity = FPM/ (.262 * Diameter)

Calculate RPM from HP & Torque

RPM from HP & Torque = HP X 63025 / Torque

Calculate Diameter or P.D. of Wheel

Diameter or P.D. of Wheel = FPM/ (.262 * RPM)

Calculate Horsepower from Torque and RPM

Horsepower = Torque * RPM / Horsepower

Calculate HP from Force and Velocity

Horse power = Force lb * FPM / 33000

Calculate Torque from HP & RPM

Torque = HP * 63025 / RPM

Calculate Torque from Force

Torque = Force lbs * Radius

Calculate Effective Force

Force = HP * 33000 / Velocity

Calculate Eff. Tension from Torque & Radius

Eff Tension = Torque / Radius

Calculate Eff. Tension from HP & FPM

Eff Tension = HP * 33000 / FPM

Calculate 3 Phase Motor Horsepower

3 phase motor horse power = Volts * Amps * Eff * PF * 1.73 / 746

Calculate DC Motor Horsepower

DC Motor horse power = Volts * Amps * Eff / 746

Kw to HP (Kilo watt to Horsepower conversion tool )

Horsepower = Kw* 1.341
