Unformatted text preview: its work in (kW) and its efficiency. (10 pts) Given: P C (ideal gas) = 32 K kmol kJ * 3. A ferrier makes a steel horseshoe by heating it to close to the melting temperature so that it can be shaped. Once the horseshoe is shaped, the ferrier hardens and sets the horseshoe by dropping it into a container of water to cool. A 1.13 kg horseshoe at 1420C is dropped into 25 kg of water in a well-insulated container. The water is initially at 5C. Given: C P (steel) = 0.49 K kg kJ * ; C P (water) = 4.2 K kg kJ * a) Determine final temperature of the water and the horseshoe. (4 pts) b) Determine the entropy change of the water and the horseshoe in going from their initial states to their final states. (4 pts)...
