An inward radial reaction turbine has an overall efficiency of 80 % and shaft er of 150 kW. The turbine is working under a head of 10 m and has peripheral

Problem 2: A turbine accepts steam at 3000kPa and 800 °C and leaves at 100 kPa with a quality of 30%. If the Criss flow rate is 5 he's determine the power puput. (Neelect kinetic & potential energy changes. Neglect heat kg/s

Answer and choose from choices

1. A rigid tank whose volume is 10 liters is initially evacuated. A pinhole develops in the wall, and air from the surroundings at 1 bar, 25C enters the pressure in the tank becomes 1 bar. No significant heat transfer beween the contents of the tank and the surroundings occur. Assuming the ideal gas model with y 1.4 for the air, determine: (a) final temperature in the tank (b) amount of air that leaks into the tank
