Question
![A closed system contains an ideal gas, which molecular weight is W-60 kg/kmol, and its
standard state entropy is so-0. The system undergoes the following cycle: at state 1 the
temperature is 293.15 K, the pressure is 94 kPa, and the entropy is 45.428 J/(kg.K). The gas is
compressed polytropically at n=1.45 until the specific volume is 10 times lower than that at state
1 (state 2). Then 84552.2 J/kg of heat is added at constant specific volume (state 3). After that
heat is added at constant pressure until entropy is 333.333 J/(kg.K) (state 4). In the next process
the system undergoes isentropic expansion (and reaches state 5). Finally there is a constant
volume rejection of heat (until state 1). Determine a) the values of p, v, T and s, at each cycle
point; b) the p-V and T-s diagrams of the cycle; c) the heat added to the system; d) the heat
rejected by the system; e) the cycle net work; f) the mean effective pressure, g) the cycle thermal
efficiency.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F35b55cc2-ac55-4b83-ad24-f42505ad4f30%2Fdb67dacb-fa47-45d0-b105-54db1a9b65bd%2F0uxtsm_processed.png&w=3840&q=75)
