This formula uses 3 Variables
Variables Used
Horsepower of engine - Horsepower of engine is defined as the power an engine produces. It is calculated through the power needed to move 550 pounds one foot in one second.
Engine Torque - (Measured in Newton Meter) - Engine Torque is defined as a rotating force produced by a engine's crankshaft due to power developed during power stroke in IC engine.
Engine RPM - (Measured in Radian per Second) - Engine RPM is defined as the number of rotations of the engine crankshaft in one minute.
STEP 1: Convert Input(s) to Base Unit
Engine Torque: 140000 Newton Millimeter --> 140 Newton Meter (Check conversion here)
Engine RPM: 5000 Revolution per Minute --> 523.598775571636 Radian per Second (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
HP = (T*Erpm)/5252 --> (140*523.598775571636)/5252
Evaluating ... ...
