A 1.8-m 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 77°C. The gas constant of air is 0.287 kPa.m³/kg.K. The properties of air are h;= 295.17 kJ/kg, u₁= 210.49 kJ/kg, and u2 = 250.02 kJ/kg. P=600 kPa T₁= 22°C V m³ P₁ = 100 kPa T₁ = 22°C lout etermine the amount of heat transfer. The amount of heat transfer Qout is -305.934 kJ.

A 1.8-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 77°C. The gas constant of air is 0.287 kPa.m³/kg-K. The properties of air are h;=
295.17 kJ/kg, ₁ = 210.49 kJ/kg, and u2 = 250.02 kJ/kg.
