The frictionless piston shown in the Figure below has a mass of 16 kg. Heat is added until the temperature reaches 400°C. If the initial quality is 20 percent, find (a) the initial pressure, b) the mass of water, (c) the quality when the piston hits the stops, (d) the final pressure, and (e) the work done on the piston. Liquid Piston 30 mm 50 mm Water vapor 100 mm
