2. (9 pts) A frictionless piston-and-cylinder device (i.e., closed system) initially contains 75kg of water vapor in equilibrium with 5kg of liquid water. The piston and the external surroundings collectively exert a total pressure of 200kPa on the fluid (i.e., steam). Then, 125MJ of heat is supplied to the fluid. What will be the final H and temperature of the fluid? Identify the system in this problem for 1 pt. Provide the appropriate form of the simplified energy balance equation for another 1pt. Hints: - You may use linear interpolation to solve for final T based on final H^ - Use Appendix A.III saturated steam data to find initial H^ - You will need to use the Lever rule to solve the initial H^ - Based on the final H^ that you will calculate, you will realize that system is a superheated vapor in the final state - Calculate the final H^ to determine final T from Appendix A
