Current Attempt in Progress
Air contained in a rigid, insulated tank fitted with a paddle wheel, initially at 300 K, 2 bar, and a volume of 2 m³, is stirred until its temperature is 500 K.
Assuming the ideal gas model for the air, and ignoring kinetic and potential energy, determine:
(a) the final pressure, in bar.
(b) the work, in kJ.
(c) the amount of entropy produced, in kJ/K.
Solve using:
(1) data from Table A-22.
(2) constant $c_v$, read from Table A-20 at 400 K.
