Air contained in a rigid, insulated cubic tank of edge 1 m, fitted with a paddle wheel, undergoes a stirring process between state 1: t1 = 40 °c, p1 = 400 kpa; and state 2: p2 = 800 kpa.(a). determine the temperature change in this process.
(b). determine the work done by the paddle wheel in this stirring process.
(c). determine the entropy generation in this process.
