Question

Find brake power for I.C. engine, friction power =1.2kW, indicated power =9.6 kW

Answer 1

• Friction power=1.2Kw
• Indicated power=9.6kW

We know

$\boxed{\sf Brake\:power=Indicated\:power-Friction \;power}$

$\\ \sf\longmapsto Brake\:power=9.6-1.2$

$\\ \sf\longmapsto Brake\:power=8.4Kw$
