During a test on a 5 cylinder four stroke IC diesel engine with a cylinder bore and stroke length of 267 mm and 293 mm respectively, running at 436 rpm, the following results were obtained: Mass on dynamometer mass hanger(arm length=0,823 m)=219,7 kg, indicated mean effective pressure=452 KPa, fuel consumption(with Qnet=39,8 MJ/kg, density=0,944 kg/l)=6 ml/s. Take acceleration due to gravity as 9,81 m per square seconds. Calculate: 1.the indicator power to 2 deimal places(not in kilos unit) 2.the brake thermal efficiency and mechanical efficiency in decimal form to 3 decimal places. 3. the brake power( not in kilos)
