The following observations were taken during a test on a single cylinder 4 stroke
cycle engine having a bore of 300 mm and a stroke of 450 mm.
Ambient air temperature =22°C
Engine speed = 300 rpm
Fuel consumption =11 kg/h
CV of fuel = 42000 kJ/kg.
Mean effective pressure = 6 bar
Rope diameter = 2 cm
Net brake load =1.0 kN
Brake drum diameter = 2 m
Quantity of Jacket cooling water = 590 kg/hr
Temperature entering cooling water = 22°C
Temperature of leaving cooling water =70°C
Quantity of air as measured = 225 kg/h
Specific heat of exhaust of gases =1.005 kJ/kgK
Exhaust gas temperature = 405°C
Determine indicated power, brake power, mechanical efficiency and draw a heat
balance sheet on hour basis.
