Brake Power given Mechanical Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

Brake Power = (Mechanical Efficiency/100)*Indicated Power
BP = (η_m/100)*IP
This formula uses 3 Variables

Variables Used

Brake Power - (Measured in Watt) - Brake Power is the power available at the crankshaft.
Mechanical Efficiency - Mechanical Efficiency (in %) is the ratio of the power delivered by a mechanical system to the power supplied to it.
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

Mechanical Efficiency: 60 --> No Conversion Required
Indicated Power: 0.9 Kilowatt --> 900 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

BP = (η_m/100)*IP --> (60/100)*900

Evaluating ... ...

BP = 540

STEP 3: Convert Result to Output's Unit

540 Watt -->0.54 Kilowatt (Check conversion here)

FINAL ANSWER

0.54 Kilowatt <-- Brake Power
