Frictional power of engine Solution

STEP 0: Pre-Calculation Summary

Formula Used

Frictional Power of Engine = Indicated Power-Brake Power
FP = IP-BP
This formula uses 3 Variables

Variables Used

Frictional Power of Engine - (Measured in Watt) - Frictional power of engine is defined as the power loss in overcoming the friction between piston and cylinder walls.
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: 140 Watt --> 140 Watt No Conversion Required
Brake Power: 1.93 Watt --> 1.93 Watt No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FP = IP-BP --> 140-1.93

Evaluating ... ...

FP = 138.07

STEP 3: Convert Result to Output's Unit

138.07 Watt --> No Conversion Required

FINAL ANSWER

138.07 Watt <-- Frictional Power of Engine

(Calculation completed in 00.004 seconds)

< For 4 Stroke Engine Calculators

Indicated Power of Four-stroke Engine

Go Indicated Power = (Number of Cylinders*Mean Effective Pressure*Stroke Length*Area of Cross Section*(Engine Speed))/(2)

Brake Mean Effective Pressure of 4S Engines given Brake power

Go Brake Mean Effective Pressure = (2*Brake Power)/(Stroke Length*Area of Cross Section*(Engine Speed))

Bmep given engine torque

Go Brake Mean Effective Pressure = (2*pi*Engine Torque*Engine Speed)/Mean Piston Speed

Horsepower of engine

Go Horsepower of Engine = (Engine Torque*Engine RPM)/5252

Frictional power of engine Formula

Frictional Power of Engine = Indicated Power-Brake Power
FP = IP-BP

What is frictional power of engine?

The Friction Power formula is defined as the difference between the indicated power and brake power of an IC engine. The friction power is defined as the difference. between the power delivered to the piston while. the working fluid is contained within the cylinder, and the usable work delivered to the drive shaft.
