Q1: A particular power plant operates with a heat-source reservoir at 370°C and a heat sink reservoir at 50°C. It has a thermal efficiency equal to 60% of the Carnot- engine thermal efficiency for the same temperatures. (a) What is the thermal efficiency of the plant? (b) To what temperature must the heat-source reservoir be raised to increase the thermal efficiency of the plant to 40%? Again n is 60% of the Carnot-engine value. (c) For part (a) If the discarded heat is 2000000kw what is the work?
