A spring-loaded piston-cylinder device is initially filled with 0.11 kg of an R-134a liquid-vapor mixture whose temperature is -340C and whose quality is 10.76 percent. The spring constant in the spring force relation F = kx is 7.49 kN/m, and the piston diameter is 29.2 cm. The R-134a undergoes a process that increases its volume by 39.34 percent. Calculate the final enthalpy of the R-134a.

Question
A spring-loaded piston-cylinder device is initially filled with 0.11 kg of an R-134a liquid-vapor mixture whose temperature is -340C and whose quality is 10.76
percent. The spring constant in the spring force relation F = kx is 7.49 kN/m, and the piston diameter is 29.2 cm. The R-134a undergoes a process that increases its
volume by 39.34 percent. Calculate the final enthalpy of the R-134a.
