Problem 2 (50 points) A closed rigid tank contains of a two-phase liquid-vapor mixture of water, with a mass of 1 kg quality of x,-0.75, and a pressure of pi = 40 kPa (State 1 ). The system is heated in a constant- volume process till the pressure reaches p2-100 kPa (State 2) Sa) Determine the temperature, T, in "C, specific volume, Pi in m'/kg, and specific internal energy, ul, in kJ/kg at state 1; (12.5 points) b) Determine the phase, the temperature, T:, in "C, and specific internal energy uz, in kJ/kg at state 2; (do not interpolate, use the closest data available in table) (12.5 points) Sketch the process on a p-v diagram and label the properties (p and v) using input data and parts a and b (5 points) 5c) d Determine the work done by the system in this process, in kJ; (5 points) oe Calculate the heat transfer to the system in this process, in kJ; (10 points) Write the assumptions and model used in this problem. (5 points) In parts a, and b: indicate the properties, phase and table number used to find the properties requested. 1Mpa 1000 kPa
