A rigid, insulated tank that is initially evacuated is connected through a valve to a supply line that carries steam at 1 MPa and 300°C. Now the valve is opened,and steam is allowed to flow slowly into the tank until the pressure reaches 1 MPa, at which point the valve is closed. Find the rate of entropy production.

A rigid, well-insulated tank contains 100 kg of liquid water at 21°C. The tank is connected through a valve to a steam main where the pressure is 1 MPa. The valve is opened and steam enters the tank until the water temperatuere rises to 65 °C, at which time the valve is closed. It is determined that there are now 107.96 kg of water in the tank. Estimate the quality of steam in the main.

A rigid, insulated vessel is divided into two compartments connected by a valve. Initially, one compartment, occupying 1.0 ft3, contains air at 50 lbf/in2, 500oR, and the other, occupying 2.0 ft3, is evacuated. The valve is opened and the air is allowed to fill both volumes. Assume the air behaves as an ideal gas and that the final state is in equilibrium.   Determine the final temperature of the air, in oR, and the amount of entropy produced, in Btu/oR.

Two insulated containers are connected through an insulated line and a valve that is closed. Both sides contain 1 kg of steam but the left side is at 300 °C while the right side is at 200 °C. The valve is opened, allowing both sides to mix and reach a common temperature and pressure. a) Is this process reversible? b) What is the final pressure and temperature of the steam, if the steam is treated as an ideal gas? c)...

An initially empty, well insulated, rigid tank with a volume of 2 m3 is fitted with a mixing device. The tank has two inlets and zero outlets. One inlet is water at 1 MPa and 600◦C while the other is saturated liquid water. Both enter the tank slowly. If the amount of work done by the mixing device is 300 kJ, what must the temperature of the saturated liquid water be if the same mass is added through both inlets...

A 1.2 m3 rigid tank initially contains steam at 8 MPa and 400 ◦C. The steam slowly comes out through a hole at the bottom until the pressure drops to P0 while keeps the temperature constant. Making the pertinent considerations determines: a) the heat transferred, in kJ when P0 = 2 MPa. b) graph the heat transfer, in kJ, versus P0 from 0.5 to 8.0 MPa

Initially (state 1) a well-insulated rigid tank contains 20 kg of a saturated liquid-vapor mixture of water at 100 kPa and half of the mass is in the liquid phase. An electric resistance heater placed in the tank is now turned on and kept on until all the liquid in the tank is vaporized (state 2). Determine (a) the initial specific volume in m3/kg, (b) the final specific entropy in kJ/kg.K and (c) change of entropy in kJ/K.

A rigid copper tank, initially containing 1 m3 of air at 295 K, 4 bar, is connected by a valve to a large supply line carrying air at 295 K, 15 bar. The valve is opened only as long as required to fill the tank with air to a pressure of 15 bar. Finally, the air in the tank is at 310 K. The copper tank, which has a mass of 20 kg, is at the same temperature as the...
