Consider filling compressed argon from a high pressure supply line as shown below. Before filling, the cylinder is empty. The valve is then opened, exposing the tank 50 bar line at room temperature until the pressure of the cylinder reaches 50 bar. The valve is then closed. For argon take cp=(5/2)R and the molecular weight to be 40 kg/kmole. You may use the ideal gas model.
A. What is the temperature right after the valve is closed?
B. If the cylinder sits in storage for a long time, how much heat is transferred (in kJ/kg)?
C. What is the pressure of the cylinder when it is shipped (after it was stored for a long time)?
