A rigid tank of volume 6 m³contains Argon at 500 kPa, 30oC. It is connected to a piston cylinder (initially at the bottom) with a line and a closed valve. The pressure in the cylinder should be 300 kPa to float the piston. Now the valve is slowly opened and heat is transferred so the argon reaches a final uniform state at 30oC with the valve open. The heat transfer takes place from a 60oC space through a conduction layer 4 cm thick with conductivity k = 0.8 W/mK and a surface area of 1.5 m². Find the final volume of the argon, the total work for the process and the total heat transfer needed. How long will the process take?
