10. A spring-loaded piston - cylinder device is initially filled with 0.15 lbm of an R-134a liquid vapor mixture whose temperature is -20°F and whose quality is 75 percent. The spring constant in the spring force relation F = kx° is 40 lbf /in, and the piston diameter is 12 in. The R-134a undergoes a process that increases its volume by 50 percent.Calculate the final temperature and enthalpy of theR-134a. [MO1]
