Question 12(Please provide a hand written solution)
Air flows through an Otto Cycle, beginning the compression process at a temperature of 50 ˚C.
The volume of gas present in the cylinder at the start of compression is 0.001 m3
. During the heat
addition process, 1200 kJ/kg of heat is added to the air. The compression ratio of the cycle is 8.5.
Using cold-air standard analysis;
Calculate the temperatures at the other states in the cycle
Write the equation and sample to determine the mass,
Write the equation and sample to determine the net work,
Write the equation and sample to determine the thermal efficiency,
Write the equation and sample to determine the volume at the end of the compression,
Write the equation or sample to determine the Mean effective pressure, and
Plot the work produced during one cycle, the maximum pressure in the cycle, the thermal
efficiency of the cycle, and the mean effective pressure for pressures at the beginning of
compression ranging between 50 kPa and 150 kPa, assuming that the air behaves as an ideal gas
with constant specific heats.
