What is the heat rejected from the system per hour if all the losses are neglected?

Question

A refrigeration system operates on the reversed Carnot cycle. The temperature for the system are

            Higher temperature = 40⁰C

            Lower temperature = 20⁰C

            The capacity of the refrigeration system is 10 TR. What is the heat rejected from the system per hour if all the losses are neglected?

            (a) 1 – 25 kJ/hr            (b) 1 – 55 kJ/hr            (c) 2 -3 kJ/hr                (d) None of the above
