Question
In an ideal Diesel cycle the temperature at the beginning and end
of compression are 57°C and 603°C respectively, whilst those at
the beginning and end of expansion are 1950°C and 870°C
respectively. Determine per kg of working fluid for which R=
0.287 kJ/kg K and y = 1.4, (a) the heat received in kJ, (b) the
heat rejected in kJ, (c) the work done in kJ, and (d) the ideal
thermal efficiency. If the compression ratio is 14:1 and the
pressure at the beginning of compression is 100 kPa, determine
the maximum pressure in the cycle.
