Figure Q6 shows a piston-cylinder device initially containing 0.03 kg of wet steam with a dryness fraction of 0.6 at 1 bar enclosed below the piston. The area of the piston is 0.08 m². At this state, the piston is resting on a stopper. A second weight is also resting on a stopper on top of the cylinder. A linear spring is attached to the bottom of the weight and the bottom end of the spring is just touching the top of the piston but exerts no force on it. Heat is now slowly transferred to the steam, causing the piston and the weight to rise so that the volume below the piston increases to double its initial volume. The mass of the piston is 4.8 kg and the mass of the weight is 6 kg. The spring constant is 0.5 kN/m. Determine: (а) The final temperature. (b) The work done by the steam enclosed in the cylinder.

Weight Piston Initial State Final State Figure Q6
Transcribed Image Text:Weight Piston Initial State Final State Figure Q6
Figure Q6 shows a piston-cylinder device initially containing 0.03 kg of wet steam with a dryness fraction of 0.6 at 1 bar enclosed below the piston. The area of the piston is 0.08 m?. At this state, the piston is resting on a stopper. A second weight is also resting on a stopper on top of the cylinder. A linear spring is attached to the bottom of the weight and the bottom end of the spring is just touching the top of the piston but exerts no force on it. Heat is now slowly transferred to the steam, causing the piston and the weight to rise so that the volume below the piston increases to double its initial volume. The mass of the piston is 4.8 kg and the mass of the weight is 6 kg. The spring constant is 0.5 kN/m. Determine: (a) The final temperature. (b) The work done by the steam enclosed in the cylinder.
