Steam enters a diffuser steadily at 300 kPa and 300 °C having a velocity of 80 m/s. The inlet diameter of the diffuser is 0.1 m and the velocity at the diffuser exit is very small compared with the inlet velocity. The heat loss from the diffuser to the surroundings is at a rate of 88 kW. If the exit pressure is 800 kPa, determine the phase description and temperature at the diffuser exit. Neglect the potential energy change throughout the diffuser. O a. Superheated vapor / 300 °C O b. Saturated vapor / 250 °C O c. Saturated vapor / 170.41 °C d. Superheated vapor / 250 °C O e. Mixture / 170.41 °C

* Your answer is incorrect. A gas undergoes a process in a piston-cylinder assembly during which the pressure-specific volume relation is pv¹.2 = constant. The mass of the gas is 0.4 lb and the following data are known: p₁ = 160 lbf/in.², V₁ = 1 ft³, and p2 = 300 lbf/in.² During the process, heat transfer from the gas is 2.1 Btu. Kinetic and potential energy effects are negligible. Determine the change in specific internal energy of the gas, in Btu/lb. Δu = i | 76.53 Btu/lb
