One of the most efficient engines ever built is a coal-fired steamturbine in the Ohio valley, driving an electric generator as itoperates between 1870°C and 430°C.

(a) What is its maximum theoretical efficiency?

(b) Its actual efficiency is 42.0%. How much mechanical power doesthe engine deliver if it absorbs 1.20105 J of energy each second from the hot reservoir?
