WN 20000 Q4: The power output of a six-cylinder four-stroke engine is absorbed by a hydraulic dynamometer for which the law is kW, where the brake load W = 540 newton and the speed N = 2500 rpm. The engine bore = 0.1 m; stroke=0.11 m and the fuel used = 15.6 kg/hr. The air consumption is measured by an air-box method with orifice diameter = 0.03 m; discharge coefficient = 0.6; the pressure difference across the orifice = 0.14 m of Hg. Take PHg =13600 kg/m³, ambient temperature = 27°C, ambient pressure = 1 bar. Determine volumetric efficiency (n.), engine torque (7), brake mean effective pressure (bmep), brake specific fuel consumption (bsfc). [20
