A six-litre, V8 SI engine operates at wide-open-throttle on a four-stroke cycle at 6000 rpm using

stoichiometric nitromethane (CH3NO2). Fuel enters the engine at a rate of 0.198 kg/s. The intake air

condition is 300 K and 105 kPa. Assume the air is ideal gas consisting of 21% O2 and 79% N2. The

universal gas constant is Ru=8.314 J/molK. Calculate:

a) The flow rate of air into the engine in kg/s

b) The volumetric efficiency of the engine in %.
