5. A reversed Carnot cycle engine, used as a heat pump, delivers 980 kJ/min of heat at 48° C. It receives heat at 18° C. Determine the power input. 6. A Carnot cycle engine using air as the working substance receives heat at 400° C and rejects it at 60° C, The minimum cylinder volume is 3.94 x 10-6 m³. The maximum cycle pressure is 2400 kPa. During addition of heat, the volume is doubled. Determine the pressure and volume at each part of the cycle.
