A rigid tank with a volume of 4 m^3 contains argon at 500 kPa and 30 deg C. It is connected to a piston cylinder (initially empt
y) with a line and a closed valve. The pressure in the cylinder should be 300 kPa to float the piston. Now the valvle is slowly opened and heat is transferred so the argon reaches a final state of 30 deg C with the valve open. The heat transfer takes place from a 60 deg C space through a conduction layer 1 cm thick with a conductivity k = 0.1 W/mK and a surface area of 1.5 m^2.
a. Find the final volume of the argon and the total work for the process.
b. Find the total heat transfer needed.
c. How long will the process take?
