(b) A and B are two reversible Carnot engines which are connected in series working between source temperature of 1500 K and sink temperature of 200 K, respectively. Carnot engine A gets 2000 kJ of heat from the source (maintained at temperature of 1500 K ) and rejects heat to second Carnot engine i.e. B. Carnot engine B takes the heat rejected by Carnot engine A and rejects heat to the sink maintained at temperature 200 K. Assuming Carnot engines A and B have same thermal efficiencies, determine: a. Amount of heat rejected by Carnot engine B b. Amount of work done by each Carnot engines i.e. A and B c. Assuming Carnot engines A and B producing same amount of work, calculate the amount of heat received by Carnot B and d. Thermal efficiency of Carnot engines A and B, respectively.
