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: 0.1 Kilowatt --> 100 Watt (Check conversion here)
Brake Power: 0.008 Kilowatt --> 8 Watt (Check conversion here)
STEP 2: Evaluate Formula
Substituting Input Values in Formula
FP = IP-BP --> 100-8
Evaluating ... ...
FP = 92
STEP 3: Convert Result to Output's Unit
92 Watt -->0.092 Kilowatt (Check conversion here)
FINAL ANSWER
0.092 Kilowatt <-- Friction Power
(Calculation completed in 00.020 seconds)
