An insulated piston-cylinder device contains 4.5 L of saturated liquid water at a constant pressure of 200 kPa. Water is stirred by a paddle wheel while a current of 20 A flows for 42 min through a resistor placed in the water. If 36% of the liquid is evaporated during this constant pressure process and the paddle-wheel work amounts to 280 kJ, determine the voltage of the source. Also, show the process on a P-v diagram with respect to saturation lines.

A 2-m3 rigid vessel contains helium initially at a gage pressure and temperature of 320 kPa and 315 K respectively. Because of the leaks in the fittings of the vessel, the gage pressure dropped to 280 kPa and the temperature decreased to 300 K, determine the mass of the helium that leaked out and also the mass of nitrogen that remained in the vessel.

A throttling steam calorimeter is an instrument used for the determination of the quality of wet steam flowing in a steam main line. It utilizes the fact that when wet steam is throttled sufficiently, superheated steam will form. If wet steam at 200 psia is throttled in a calorimeter to 15 psia and 300 oF, determine the quality of the wet steam.
