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.

650 kg/min of superheated steam at 13 Mpa, 582 deg. C enters the turbine and initially expands isentropically to the pressure of 9.2 Mpa. After partial expansion, the steam was reheated with the same pressure at 9.2 Mpa and leaves the first reheater at 520 deg. C. It is once again expanded for the second partial expansion to a pressure of 5.4 Mpa where extraction of steam occurs. The remaining steam was reheated to a pressure of 4.9 Mpa and regained a temperature of 470 deg. C after the addition of heat in the second reheater.
