SOLVE AS NONE COLD AIR SRANDARD
4. A cold-air-standard Diesel cycle with a compression ratio of 17 reaches a maximum
temperature of 2500 K in the cycle. Pressure and temperature at the beginning of the
compression process are 89 kPa and 15oC, respectively.
a. Determine the cut-off ratio.
b. Determine the heat added, in kJ/kg.
c. Determine the heat rejected, in kJ/kg.
d. Determine the thermal efficiency of the cycle.
e. Show the cycle on a T-s diagram with temperature indicated at each state.
