a piston/cylinder contains liquid water at 2 degrees Celcius, with a freely moving piston maintains a pressure of 200 kPa on the water. Heat transfers to the liquid water until the piston/cylinder contains only saturated vapor.
a.) Find the final temperature, specific work, and specific heat transfer for the process, assuming that the change in potential energy is negligible.
b.) Use the algebraic scaling technique taught in class to estimate the values of the delta Zcg and the piston's rise, delta Zpiston, that would result in a 1% error in the problem solution. Where delta Zcg is the change in the elevation of the water's center of gravity and delta Zpiston is the change in elevation of the piston.
