GAS POWER CYCLES

An engine working on limited pressure cycle has a bore diameter of 250 mm and stroke length of 300 mm. The compression ratio of the engine is 10. Fuel Injection takes place for a volume of 5 percentage of swept volume.The maximum and minimum pressures in the cycle are 65 bar and 1 bar. The compression begins at a temperature of 40 degree Celsius Determine (i) Mass of the air (ii) Heat supplied. (iii) Air standard Efficiency (iv) Power developed in kW if number of cycles per second is 3.(v) mean effective pressure.
