In Rankine cycle, the work output from the turbine is given by A Change in entropy between inlet and outlet B) Change in temperature between inlet and outlet C Change in internal energy between inlet and outlet D) Change in enthalpy between inlet and outlet

Increasing the temperature of the hot reservoir of a Carnot-cycle engine will increase the efficiency of the engine. a) True b) False

Consider a heat engine with a cycle described by the figure, with the volume and pressure at points A, B, C, and D given below. VA = 0.95 × 10-3 m3VB = 3.5 × 10-3 m3PA = 2.65 × 106 N/m2PB = 2.37 × 106 N/m2PC = 0.75 × 106 N/m2PD = 1.29 × 106 N/m2 a)Calculate the net work output, in joules, of the heat engine following path ABCDA.
