A rigid tank contains a saturated liquid-vapour mixture of water in an equilibrium state. The volume of the tank is 110 m3 and the temperature of the water in the tank is 115°C. In the tank, 70% of the mass is liquid and 30% of the mass is vapour. Please calculate the total mass of water in the tank.

Expert Solution

Steps:

i. Find the dryness fraction of the mixture.

A well-insulated rigid tank contains 3kg of saturated liquid vapour-mixture of water at 250kpa. Initially, three quarters of the mass is in the liquid phase. An electric resistance heater placed in the tank is turned on and kept on until all the liquid in the tank is vaporizer. Assuming the surroundings to be 25 degrees Celsius and 100kpa Determine: a) The exergy destruction and b) The second law efficiency for the process.

A 500 L rigid tank contains a saturated water mixture at 200 C as shown: the mixture is 40% liquid and 60% vapour by volume (State 1). A valve on top of the tank is opened, and saturated vapor is slowly withdrawn from the tank. Heat transfer occurs during this process such that the temperature in the tank remains constant. The valve is closed when 50 % of the initial mass is withdrawn from the tank (State 2) (a) Determine...
