i) Indicated Power (ip) is defined as the power developed by combustion of fuel in the cylinder of engine. It is always more than brake power. ii) Mechanical efficiency : ηm : It is a measure of mechanical perfection of the engine or its ability to transmit power developed in the engine cylinder to the crank shaft .

What is mean by indicated power?

The indicated power of an I.C engine is the total power developed within the cylinder in one complete cycle neglecting any losses. It is the sum total of the brake power and the friction power of an engine. ... You can measure the indicated power of an engine by using the indicator diagram or power card diagram.

What is the brake power and indicated 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.
