image of a PC Model T-s diagram Ex 2 The following information are known about an iron projectile of mass 50 kg at two different states. State-1: T= 30oC, Vel=0 m/s, Elevation (z) = 0 m; State-2: T= 300oC, Vel=50 m/s, Elevation (z) = 50 m. Determine (a) the change in stored energy, and the contribution to the change due to: (b) change in velocity and (c) change in PE. (d) What-if scenario: What would be the change in stored energy if the final temperature were 500 deg-C?

The solution illustrates use of the I/O panel to set independent parameters of a problem. (Ans: 6162 kJ, 62.5 kJ, 24.5 kJ; 10662 kJ)

Ex 1 Determine the change in (a) stored energy, (b) internal energy, (c) entropy, and (d) stored exergy of a 1000 kg block of granite as it is heated from atmospheric temperature to a temperature of 1000 deg-C. Assume the atmospheric conditions to be 100 kPa and 25 deg-C. Use the SL model. (Ans: 770 MJ, 770 MJ, 1.146 MJ/K, 428.3 MJ) (Contributed by : A. FERRELL)
