4 16 An imaginary engine receives heat and does work on a slowly moving piston at such rates that the cycle of operation of 1 kg of working fluid can be represented as a circle 10 cm in diameter on a p v diagram on which 1 cm 300 kPa and 1 cm 0 1 m kg a How much work is done by each kg of working fluid for each cycle of operation b The thermal efficiency of an engine is defined as the ratio of work done and heat input in a cycle If the heat rejected by the engine in a cycle is 1000 kJ per kg of working fluid what would be its thermal efficiency L0421 Ans a 2356 19 kJ kg b 0 702
