- One-quarter lbmol of oxygen gas (O2) undergoes a process from p1 = 20 lbf/in2, T1 = 500oR to p2 = 150 lbf/in2. For the process W = -500 Btu and Q = -202.5 Btu. Assume the oxygen behaves as an ideal gas. Determine T2, in oR, and the change in entropy, in Btu/oR.Steam enters a converging-diverging nozzle operating at steady state with P-40 bar, T-400°C, and a velocity of 10 m/s. The steam flows through the nozzle adiabatically and no significant change in elevation. At the exit, p2=1.5 MPa, and the velocity is 665 m/s. The mass flow rate is 2 kg/s. Determine the exit area of the nozzle, in (m²). also, drive the (T-V) diagram for the steam.Can someone explaine this problem please? A closed system contains an ideal gas, which molecular weight is W = 63.47 kg/kmol, and its standard state entropy is S0 = 0. The system undergoes the following cycle: at state 1 the temperature is 295.15 K, the pressure is 95 kPa (absolute), and the entropy is 46.450 J/(kg/kmol). The gas is compressed polytropically at n = 1.46 until the specific volume is 10 times lower than that at state 1 ( state 2 ). Then 85651.7 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 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)…

Assuming methane has a constant Cp of 2.2537 kJ/(kg K), use the Generalized Charts provided on eClass to determine:a) the pressure of Stream 1 (in MPa) and the temperature of Stream 2 (in K)b) the quality of the exit stream in %c) the entropy generation per kg being throttled, in kJ/(kg K)d) the specific volume of the methane in Stream 1, in m3/kgNote: Use the Generalized Charts provided on eClass to solve this problem. You will not be able to use the Charts in the textbook to solve this problem since they do not cover all the regions of the phase diagram.Q: 1.1m³ of air is heated reversibly at constant pressure from 25°C to 310°C, and then cooled reversibly at constant volume back to the initial temperature, the initial pressure is 1 bar.
