A rigid tank contains air at 500 kPa and 190 °C. As a result of heat transfer to the surroundings, the temperature and pressure inside the tank drop to 64 °C and 400 kPa respectively. One kilogram of water fills a container whose volume is 0.13 m cube. The pressure in the container is 750 kPa. Calculate the total internal energy and enthalphy in the container.

Expert Solution

Answer- total internal energy= 1648.31Kj

Total enthalpy in container= 1749.8Kj

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 A valve on top of the tank is opened, and saturated vapor is slowly withdrawn from the tank.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 The valve is closed when 50 % of the initial mass is withdrawn from the tank (State 2) (a) Determine...

A 200 litre tank initially contains water at 100 kPa and a quality of 1%. Heat is transferred to the water, thereby raising its pressure and temperature. At a pressure of 2 MPa, a safety valve opens, and saturated vapour at 2 MPa flows out. The process continues, maintaining 2 MPa inside until the quality in the tank is 90%, then stops. Determine the total mass if water that flowed out and the total heat transfer. *I’ve seen others have...

A closed, rigid tank fitted with a paddle wheel contains 2.2 kg of air, initially at 200oC, 1 bar. During an interval of 20 minutes, the paddle wheel transfers energy to the air at a rate of 1 kW. During this time interval, the air also receives energy by heat transfer at a rate of 0.5 kW. These are the only energy transfers. Assume the ideal gas model for the air, and no overall changes in kinetic or potential energy....
