A particular power plant operators with a heat source reservoir at 350oC and a heat sink reservoir at 30oC. It has thermal efficiency equal to 55% 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 35%? Again n is 55% of the Carnot engine value?
