Three pоunds оf superheаted vаpоr is contаined in a piston-cylinder assembly, initially occupying a volume V1 = 30 ft3 at T1 = 300oF with u1 = 1104.6 Btu/lb. The vapor undergoes two processes in series: Process 1-2: Constant-temperature compression to V2 = 11.19 ft3, during which there is an energy transfer by heat from the vapor of 1275 Btu. Process 2-3: Constant-volume heating to a saturated vapor state at p3 = 120 lbf/in2 . Sketch the two processes on a T–v diagram and clearly identify the states. Determine the work in Process 1-2. Determine the heat transfer in Process 2-3. Use the tables provided. You can write your answers with units in the text box below and UPLOAD your work.
