STEP 0: Pre-Calculation Summary
Formula Used
Mechanical Efficiency = (Brake Power/Indicated Power)*100
ηm = (BP/IP)*100
This formula uses 3 Variables
Variables Used
Mechanical Efficiency - Mechanical Efficiency (in %) is the ratio of the power delivered by a mechanical system to the power supplied to it.
Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Indicated Power - (Measured in Watt) - Indicated power is the total power produced due to combustion of fuel within the IC engine's cylinder in one complete cycle neglecting any losses.
STEP 1: Convert Input(s) to Base Unit
Brake Power: 0.008 Kilowatt --> 8 Watt (Check conversion here)
Indicated Power: 0.1 Kilowatt --> 100 Watt (Check conversion here)
