Question

Examples

Ex. 1. A four stroke SI engine has the compression ratio of 6 and swept volume of 0.15 m³. Pressure and temperature at the beginning of compression are 98 kPa and 60ºC. Determine the pressure, volume and temperatures at all salient points if heat supplied to it is 150 kJ/kg. Also find out entropy change, work done, efficiency and mean effective pressure of cycle. Assuming cp = 1 kJ/kg K, c, = 0.71 kJ/kg . K. Also plot the cycle on T-S diagram.​

Answer 1

Assuming cp = 1 kJ/kg K, c, = 0.71 kJ/kg . K. Also plot the cycle on T-S diagram.
