In a trial on a four-cylinder engine of 100 mm bore, 150 mm stroke and working on a four-stroke cycle, the following observations were made: Speed = 2500 rpm, Net Dynamometer load at 500 mm radius = 200 N Power required to rotor with ignition off=4.5 kW Petrol consumption = 200 g/min Cooling water circulated = 7.5 kg/min Temperature rise of cooling water = 50° C If the CV of the petrol is 46000 kJ/kg Prepare a heat balance sheet for the engine.
