A system consisting of air initially at 300 K and 1 bar
Chapter 6, Problem 6.68(choose chapter or problem)
A system consisting of air initially at 300 K and 1 bar experiences the following two different types of interactions. In each case, the system is brought from the initial state to a state where the temperature is 500 K, while volume remains constant.
(a) The temperature rise is brought about adiabatically by stirring the air with a paddle wheel. Determine the amount of entropy produced, in kJ/kg \(\cdot \) K.
(b) The temperature rise is brought about by heat transfer from a reservoir at temperature T. The temperature at the system boundary where heat transfer occurs is also T. Plot the amount of entropy produced, in kJ/kg \(\cdot \) K, versus T for T \(\geq\) 500 K. Compare with the result of (a) and discuss
