Water at 300 F, quality 50% is contained in a cylinder/piston arrangement with initial volume 2 ft3.

Question:

Water at 300 F, quality 50% is contained in a cylinder/piston arrangement with initial volume 2 ft3. The loading of the piston is such that the inside pressure is linear with the square root of volume as P 14.7 CV0.5 lbf/in 2. Now heat is transferred to the cylinder to a final pressure of 90 lbf/in 2. Find the heat transfer in the process.
