Indicated Power given Mechanical Efficiency Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Brake Power: 0.55 Kilowatt --> 550 Watt (Check conversion here)
Mechanical Efficiency: 60 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

IP = BP/(η_m/100) --> 550/(60/100)

Evaluating ... ...

IP = 916.666666666667

STEP 3: Convert Result to Output's Unit

916.666666666667 Watt -->0.916666666666667 Kilowatt (Check conversion here)

FINAL ANSWER

0.916666666666667 ≈ 0.916667 Kilowatt <-- Indicated Power
