A particular power plant operates with a heat-source reservoir at 350°C and a heatsink reservoir at 30°C. It has a thermal efficiency equal to 55% of the Carnot-engine thermal efficiency for the same temperatures. What is the thermal efficiency of the plant? To what temperature must the heat-source reservoir be raised to increase the thermal efficiency of the plant to 35%? Again, η is 55% of the Carnot-engine value
