6. (11 marks total) A well-insulated cylinder is fitted with a piston which maintains a constant pressure of P=300kPa in the cylinder. The cylinder is initially filled with 0.2kg of steam at a temperature of T1=170C. A mass of 0.5kg of liquid water at Ti=20C is then injected into the cylinder. (a) (3 marks) Write an expression for the work done in the process. (b) (2 marks) Write the first law for this process, stating any assumptions. (c) (6 marks) The final state is a saturated mixture. Determine the final quality x2 and the work done.
