Problem 3 A rigid, insulated tank filled with 0.6 kg of air is initially at 2 bar, 20°C. The air is stirred by a paddle wheel until its pressure is 2.5 bar. The volume specific heat (Cv) is constant with 0.72 kJ/KgK. Let To = 20°C, po = 1 bar ATTENTION: You are NOT allowed to use Table A-22 to find properties in this problem. Use the volume specific heat to find properties as needed. (a) Determine the final temperature in K (b) Determine, the work done on the air by the paddle wheel, in kJ. (c) Determine the change in exergy of the air, in kJ. bar 20023
