An isolated piston-cylinder device contains 5 L of saturated liquid water at a constant pressure of 175 kPa. The water is stirred with a paddle wheel while a current of 8 A flows for 45 minutes through a resistor placed in the water. If the Half of the liquid evaporates during this process at constant pressure and the work done by the paddlewheel is equal to 400 kJ, determine the voltage of the source. Also, show the process on a P-v diagram with respect to the saturation lines.
