Expert Solution
Solution:- The given process is a constant volume process and it has been assumed that no heat transfer takes place across the walls of the rigid tank. Standard values of CV (Specific heat at constant volume) and R (Universal gas constant) for air have been assumed to solve the problem.

An insulated, rigid tank whose volume is 0.5 m3 is
connected by a valve to a large vessel holding steam at 40 bar,
480°C. The tank is initially evacuated. The valve is opened only as
long as required to fill the tank with steam to a pressure of 20
bar.
Determine:
(a) the final temperature of the steam in the tank, in °C, the
final mass of the steam in the tank, in kg, and
(b) the amount of entropy...

A rigid tank of volume 0.63 m3 initially has some air inside at
0.5 bar and 300 K. A hole develops in the wall, and air from the
surroundings at 1 bar, 300 K flows in until the pressure in the
tank reaches 1 bar. Heat transfer between the contents of the tank
and the surroundings is negligible. Determine the final temperature
in the tank, in K. What is the entropy generation of the process?

A volume of 8.62 m3 of air in a rigid, insulated container
fitted with a paddle wheel is initially at 322 K, 0.4 bar. The air
receives 481 kJ by work from the paddle wheel. Assuming the ideal
gas model with cv = 0.71 kJ/kg • K, determine for the air the
amount of entropy produced, in kJ/K.
