4-36EA spring-loaded piston-cylinder device is initially filled with 0.13 lbm of an R-134a liquid-vapor mixture whose temperature is -30°F and whose quality is 80 percent.The spring constant in the spring

force relation Fis 37 lbf/in, and the piston diameter is 12 in. The R-134akrt-undergoes a process that increases its volume by 50 percent.of Calculate the final temperature and enthalpy of the r 134 a
