Friction Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Friction Power = Indicated Power-Brake Power
FP = IP-BP
This formula uses 3 Variables

Variables Used

Friction Power - (Measured in Watt) - Friction Power is the power lost in an internal-combustion engine through friction between parts of the machine itself.
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.

STEP 1: Convert Input(s) to Base Unit

Indicated Power: 0.9 Kilowatt --> 900 Watt (Check conversion here)
Brake Power: 0.55 Kilowatt --> 550 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FP = IP-BP --> 900-550

Evaluating ... ...

FP = 350

STEP 3: Convert Result to Output's Unit

350 Watt -->0.35 Kilowatt (Check conversion here)

FINAL ANSWER

0.35 Kilowatt <-- Friction Power
