The vapor exits at p2 = = 360° C enters a turbine operating at steady state with a volumetric flow rate 1.5 bar, T₂ = 230° C with no stray heat transfer to the surroundings. Determine the power produced by the turbine Wcy in kW. Assume kinetic and potential energy effects are negligible. CV W cv = CV = Ex: 111.0 kW Water vapor P1, T₁ 1|(AV)1 Turbine 0 2 V P2, T2

3. Steam enters a diffuser operating at steady state with a pressure of 3 bar, a temperature of 200 °C, and a velocity of 100 m/s. Steam exits the diffuser as a saturated vapor, with a velocity of 10 m/s. Heat transfer occurs from the steam to its surroundings at a rate of 200 kJ/kg of steam flowing. Neglecting potential energy effects, determine the exit pressure, in bar. (Note: 1 kJ/kg-1000 m²/s²) (1) (2) Quick handwritten,no gpt.

Steam enters a turbine operating at steady state at 750°F and 450 lbf/in² and leaves as a saturated vapor at 0.8 lbf/in². The turbine develops 12,000 hp, and heat transfer from the turbine to the surroundings occurs at a rate of 2 x 106 Btu/h. Neglect kinetic and potential energy changes from inlet to exit. Determine the exit temperature, in °F, and the volumetric flow rate of the steam at the inlet, in ft³/s. Step 1 Determine the exit temperature, in °F. T₂ = i °F.

Argon gas flows through a well-insulated nozzle at steady state. The temperature and velocity at the inlet are 550°R and 150 ft/s, respectively. At the exit, the temperature is 480°R and the pressure is 40 lbf/in². The area of the exit is 0.0085 ft². Use the ideal gas model with k = 1.67, and neglect potential energy effects. Determine the velocity at the exit, in ft/s, and the mass flow rate, in lb/s. Step 1 Determine the velocity at the exit, in ft/s. V₂ = i ft/s
