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 50cm², 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) Table 1.0: Ideal gas specific heats of various common gases Gas constant, R kg-K kikg-K Gas Formula 0.2870 0.2081 0.1433 0.1889 0.2968 0.2765 0.2964 2.0769 4.1240 0.5182 1.005 0.5203 1.7164 0.846 1.040 1.7662 1.5482 5.1926 14.307 2.2537 0.718 0.3122 1.5734 0.657 0.744 1.4897 1.2518 3.1156 10.183 1.7354 1.400 1.667 1.091 1.289 1.400 1.186 1.237 1.667 1.405 1.299 Air Argon Butane Carbon diaxide Carbon monoxide Ethane Ethylene Helium Hydrogen Methane CH. 0.4110 10000
