I just need help with parts (f), (g), (h) and (i) Problem 6: A certain gasoline engine is modeled as a monatomic ideal gas undergoing an Otto cycle, represented by the p-V diagram shown in the figure. The initial pressure, volume, and temperature are p1 = 0.95 × 105 Pa, V1 = 0.025 m3, and T1 = 310 K, respectively. Part (a) Calculate the number of moles times the gas constant, nR, in joules per kelvin, to three significant figures, using the ideal-gas law and the initial values of pressure, volume, and temperature. This quantity will be useful for later calculations. nR = 7.7 Part (b) The first step in the Otto cycle is adiabatic compression. Enter an expression for the work performed on the gas during the first step, in terms of V1, V2, and p1. W1→2 = p1 V1 ( ( V1/V2 )( 2/3 ) - 1 )/( 2/3 ) Part (c) Calculate the work performed on the gas during the first step, in joules, for V2 = V1/6.2.

Consider a variation of the Carnot cycle in a closed system with 10 kg of pure water operating. ranging between temperatures of 130 C and 350 ◦C. State 1 is a saturated liquid. Process 1-2 is a isothermal expansion with a supply of QH = 10 MJ. Process 2-3 is an adiabatic expansion with isentropic efficiency from 0.75 to minimum temperature. Process 3-4 is a compression isothermal, and the 4-1 process is a reversible adiabatic compression. Calculate: a. The pressure p2, the bonds x4 and x3, and the specific entropies s1 and s3; b. The work in each expansion and compression process; c. The heat rejected QL, the net work produced Wl i q and the yield η of the cycle; d. The entropy generated Sg in the cycle
In a steady-state operating power plant, saturated liquid H2O at 122 deg C is fed to a boiler at 3.756 m/s through a pipe (0.03 m diameter). It leaves the boiler at 9 bar and 88.7 m/s. Then, it enters the turbine through a constant 0.13 m diameter pipe. The exit pipe of the turbine is 0.3 m in diameter and T = 310ºC while P = 1.37 bar. If 2.5 kg/s water is fed and there is change in KE, prove that the fluid enters the turbine at 637.06 deg C.
C. In an ideal gas turbine power device, the pressure ratio is 6, the temperature entering the compressor is 27°C, and the maximum allowable temperature of the turbine is 816°C. What is the efficiency of this power device when it is carried out in reversible operation? However, the specific ratio is 1.4. (a)20% (b)30% (c)40% (d)50%
A Carnot Power Cycle Operates on 2 lb of air between the limits of 70°F and 500°F . The pressure at the beginning of the isothermal expansion is 400 psia and at the end of isothermal expansion is 185 psig. Determine a.the volume at the end of the isothermal compression b.Change in entropy during the isothermal process c.heat added
2. Water enters the boiler of a steady-flow Carnot engine as a saturated liquid at 300 psia and leaves with a quality of 0.96. Steam leaves the turbine at a pressure of 20 psia. Show the cycle on a T-s diagram relative to the saturation lines, and determine (a) the thermal efficiency, (b) the quality at the end of the isothermal heat-rejection process, and (c) the net work output.
If one measurement is conducted in the four processes and shows that the pressure ratio (P3/P2)in the adiabatic expansion is 1.2 times the pressure ratio (P4/P1) in the adiabatic compression, can you justify if it is a Carnot engine? Please give your reason
