A 2.2-m3 rigid tank initially contains air at 100 kPa and 22°C. The tank is connected to a supply line through a valve. Air is flowing in the supply line at 600 kPa and 22°C. The valve is opened, and air is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. A thermometer placed in the tank indicates that the air temperature at the final state is...

SP04 A rigid, poorly insulated tank with a volume of V1.0 m3 initially contains a saturated water vapor (quality of 1.0) at a pressure of 3 bars (300 kPa). The tank is connected to a supply line containing steam at a pressure of pL- 10 bars (1000 kPa) and a temperature of TL 500°C. The valve is opened and 2.0 kg of steam enters the rigid tank, after which the valve is closed. The pressure is measured after the valve...

1. A rigid (constant volume) tank sealed by a valve initially contains 100 kg of air at a pressure of 100 kPa and 300 K. At time t = 0, the valve for the air tank is opened in a controlled manner and air leaks out isothermally (constant temperature) of the tank at a constant mass flow rate of 1 kg/s. The valve is closed after 75 seconds. Answer the following questions: Assuming air is an ideal gas, what is...

A rigid tank whose volume is 3 m3, initially containing air at 1 bar, 295 K, is connected by a valve to a large vessel holding air at 6 bar, 295 K. The valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 320 K. Assuming the ideal gas model for the air determine the heat transfer between the tank contents and the surroundings, in kl....

A rigid copper tank, initially containing 1 m^3 of air at 295K, 5 bar, is connected by a valve to a large supply line carrying air at 295K, 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 air in...

Air is contained in a 100 liter rigid tank and is initially at 40 oC and 900 kPa. The air is cooled until the pressure drops to 400 kPa. Find the final temperature and the amount of heat transfer during the process. Consider air as ideal gas with constant specific heat.

A 1-mº rigid tank contains 100 kg R-134a at a temperature of 16 °C. A valve on top of the tank is opened, and saturated vapor is allowed to escape through a throttle to a collector system at 100 kPa. During the process the temperature inside the tank remains at 16 °C by heat transfer from the 20 °C surroundings. The valve is closed when no more liquid remains inside the tank. Calculate the heat transfer to the tank and...
