A motor supplies 100 horsepower (hp) to a shaft which drives a propeller blade. The shaft rotates in a bearing that is under-lubricated, and thus the shaft experiences significant friction while rotating in this bearing during operation. In this case, it is reasonable to assume that the power input to the propeller is equal to the power output from the motor.
