5.14 The air flow to a four cylinder, four-stroke oil engine is measured by
means of a 5 cm diameter orifice having a coefficient of discharge of 0.6.
During a test on the engine the following data were recorded : bore =
10 cm; stroke = 12 cm; speed = 1200 rpm; brake torque = 120 Nm;
fuel consumption = 5 kg/h; calorific value of fuel = 42 MJ/kg; pressure
drop across orifice is 4.6 cm of water; ambient temperature and pressure
are 17 °C and 1 bar respectively. Calculate (i) the thermal efficiency on
brake power basis; (ii) the brake mean effective pressure and (iii) the
volumetric efficiency based on free air condition.
