Question

#59 The Dornier is a light freighter and feeder liner aircraft powered

#59 The Dornier is a light freighter and feeder liner aircraft powered by two Lycoming IGSO-540- A1A six-cylinder horizontally opposed engines, each rated at 260 kW. Assume that the Otto cycle represent the cycle for such a spark-ignition engine. Data for the engine is as follows

Compression ratio: 8

Temperature and pressure at the beginning of the compression stroke: 300 K and 96 kPa

Rate of heat transfer during the constant volume stroke: 760 kJ/kg.

Specific heat at constant volume: 0.72 kJ/(kg · K)

Calculate

a) The pressure and temperature at the end of the heat addition process

 b) Network output

c) Air mass flow rate

d) Mean effective pressure
