ME 3322 — Thermodynamics Name: Unit: 2 Level: 2 ID: 0027.1 Date: The piston-cylinder assembly shown in the figure is fitted with a linear spring. The spring constant is k = 15 kN/m and the neutral position of the spring is when the piston is all the way to the left end of the cylinder, i.e., y = 0. The piston face area is 150 cm 2 and it is initially 30 cm from the left end of the cylinder. Superheated water vapor initially at 400 °C is contained in the left side of the assembly and the right side is evacuated. The water is heated until the piston moves 20 cm to the right.

Unformatted text preview: Determine the mass of the water and the magnitude and direction of the work and heat transfer for this process. Sketch the process on a p-v diagram. Neglect any changes in kinetic and potential energy. Answer: State your results in terms of properties obtained from tsc. Make sure all needed quantities are identified and computed. Check your answers using v 1 = 1.0315 m 3 /kg, u 1 = 2966.0 kJ/kg, and u 2 = 5340.6 kJ/kg. You will find m = 0.00436 kg, W 12 = –1.2 kJ (out), and Q 12 = 11.56 kJ (in)....

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
