Water vapor enters a diffuser at a pressure of 0.7 bar, a temperature of 160°C, and a velocity of 180 m/s. The inlet to the diffuser is 100 cm The exit conditions from the diffuser are: velocity of 60 m/s and pressure of 1.0 bar. During the passage of the water vapor through the diffuser, there is heat transfer to the surroundings of 0.6 kJ/kg. Determine (a) the final temperature. (b) the mass flow rate in kg/s, and (c) the...

5. A steam turbine operates with an inlet condition of 30 bar, 400 °C, 160 m/s and an outlet state of a saturated vapour at 0.7 bar with a velocity of 100 m/s. The mass flow rate is 1200 kg/min and the power output is 10800 kW. Present the process on the T-v diagram. Determine the magnitude and direction of the heat-transfer rate in kJ/min if the potential energy change in negligible.
In a cogeneration plant, 10% kg/h of steam at 80 bar, 480 °C expands in the h.p. turbine to 10 bar. From the exhaust 4 x 10 kgh of steam is extracted for process heating. The remaining steam expands in the l.p. turbine to 0.08 bar. Saturated liquid at 0.0
