Aheat engine that operates on a carnot cycle between 150 ? c and 10 ? c is used to accelerate a flywheel from rest to a rotational speed of 8.50 s? 1. the 1700-kg flywheel is a solid uniform cylinder that rotates about its long central axis without appreciable friction. its diameter is 1.00 m, and it is 750 mm long.
a) how much thermal energy must be transferred into this engine to accelerate the flywheel to the desired rotational speed?
b) how much of this thermal energy is wasted in the process?
