A piston-cylinder assembly contains 3 kg of water at 120oC and 1.5 bar. The water is compressed to liquid-vapor mixture state where the pressure is 4 bar, quality 80%. During the compression, there is a heat transfer of energy from the water to its surroundings having a magnitude of 350kJ. Neglecting changes in kinetic energy and potential energy. Determine the specific internal energy at state 1 (u1), in kJ/kg Determine the specific internal energy at state 2(u2), in kJ/kg Determine the work for the process, in kJ, and judge the direction of energy flow by the work (into the system or from the system)
