Unformatted text preview: Neglect changes in kinetic and potential energy. Answer: State the results in terms of the problem parameters and properties obtained from tsc. Make sure all needed quantities are identified and computed. If h 2 – h 1 = 318 kJ/kg and v 1 = 0.83369 m 3 /kg, then = –643 W. c Q ±...
