The compression ratio for a single-cylinder engine operating on dual cycle is

The compression ratio for a single-cylinder engine operating on dual cycle is 9. The maximum pressure in the cylinder is limited to 60 bar. The pressure and temperature of the air at the beginning of the cycle are 1 bar and 30C. Heat is added during constant pressure process upto 4 per cent of the stroke. Assuming the cylinder diameter and stroke length as 250 mm and 300 mm respectively, determine : (i) The air standard efficiency of the cycle. (i) The power developed if the number of working cycles are 3 per second. Take for air = 0.71 kJ/kg Kand: c = 1.0. kJ/kg K
