Problem 03.063 - Spring loaded piston-cylinder device The spring-loaded piston-cylinder device shown in the figure is filled with 0.45 kg of water vapor that is initially at 4 MPa and 400C. Initially, the spring exerts no force against the piston. The spring constant in the spring force relation F= kx is K = 0.9 kN/cm and the piston diameter is D = 20 cm. The water now undergoes a process until its volume is one-half of the original volume. Calculate the final temperature and the specific enthalpy of the water. Use data from the steam tables. - Spring Steam The final temperature is The specific enthalpy is kJ/kg
