(a) A four cylinder engine operates at 1200 rpm gave 18.6 KW brake power, the average torque when one cylinder was cut-off was 105 N-m. Evaluate the indicated thermal efficiency if the Calorific value of the fuel is 42000 kJ / Kg and the engine uses 0.34 Kg of petrol per brake power hour.
(b) A gas turbine unit receives air of 100 KPa and 3000 K and compresses it adiabatically to 620 KPa with minimum efficiency of compressor 88%. The fuel has a heating value of 44180 kJ / Kg and fuel air ratio is 0.017 Kg fuel per Kg air. The turbine internal efficiency is 90%. Determine the Compressor work, thermal efficiency and turbine work.
