Question
A certain ideal gas (unknown) inside a close piston-cylinder assembly undergoes a set of processes
that composed of Isothermal expansion from State point 1 to state point 2, Isometric heat rejection
from state point 2 to state point 3, and Isentropic compression from state point 3 back to the initial
condition. If the maximum pressure is 3000kPa and maximum and minimum volume is 200cm³ and
50cm?, analyze the problem and perform the following:
a. Draw and label the graph of this set of processes in the P-V and T-S diagram showing the state
point numbers and energy directions.
b. From the known ideal gases as shown in Table 1.0, select the best suited ideal gas to attain the
processes stated if the lowest pressure is limited to 629.8kPa. Assume a constant specific heat.
c. For the selected ideal gas from b, compute the work of compression (kJ/kg), work of expansion
(kJ/kg), and heat rejected (kJ/kg)
