Mechanical Efficiency using Indicated Power and Friction Power Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mechanical Efficiency = (Indicated Power of 4 Stroke-Friction Power)/Indicated Power of 4 Stroke
η_m = (P_4i-P_f)/P_4i
This formula uses 3 Variables

Variables Used

Mechanical Efficiency - Mechanical Efficiency is measure of the effectiveness with which a mechanical system performs.
Indicated Power of 4 Stroke - (Measured in Watt) - Indicated Power of 4 Stroke is a measure of the power output of a 4 stroke diesel engine based on the pressure exerted on the piston during the combustion process.
Friction Power - (Measured in Watt) - Friction Power refers to the power that is lost due to friction between the moving parts of the engine.

STEP 1: Convert Input(s) to Base Unit

Indicated Power of 4 Stroke: 7553 Kilowatt --> 7553000 Watt (Check conversion here)
Friction Power: 2016 Kilowatt --> 2016000 Watt (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

η_m = (P_4i-P_f)/P_4i --> (7553000-2016000)/7553000

Evaluating ... ...

What is the relation between indicated power brake power and friction power?

The difference between indicated power and brake power is as follows. First of all, by indicated power we mean GROSS indicated power, the total work done by gas on piston during compression and power strokes. The brake power is the power available at the dynamometer. The difference is called friction power.
