Please help me with this problem using steam tables :,( A cylinder-piston system initially contains water at P= 20 atm and T= 240°C. The piston moves to a final position, where the volume is twice the initial volume. During the movement of the piston there is heat transfer that allows to maintain constant the pressure inside the cylinder.
a) Represent the process in a P-v diagram, indicating the relative position of the saturation curve.
b) Find the work done per kilogram of water during expansion.
c) Find the heat transferred per kilogram of water during expansion.
d) Find the value of the enthalpy of water after expansion.
