What is the friction power of an engine that has 575 brake horsepower and 720 indicated horsepower?

Friction power is the difference between indicated power (IP) and brake power (BP).

Friction power = Indicated Power (IP) - Brake Power (BP)

Friction power = 720 hp - 575 hp = 145 hp

Therefore, the friction power of the engine is $\boxed{145 \text{ hp}}$.
