Homework 2 Problem 1: A piston-cylinder device initially contains 0.35-kg steam at 3.5 MPa, superheated by 7.4 C. Now the stream loses heat to the surroundings and the piston moves down, hitting a set of stops at which point the cylinder contains saturated liquid water. The cooling continues until the cylinder contains water at 200C. Determine (a) the final pressure and the quality (if mixture), (b) the boundary work, (c) the amount of heat transfer when the piston first hits...

A piston–cylinder device initially contains 0.6 m3 of saturated water vapor at 250 kPa. At this state, the piston is resting on a set of stops, and the mass of the piston is such that a pressure of 300 kPa is required to move it. Heat is now slowly transferred to the steam until the volume becomes 1.5 m3. Use the data from the steam tables. a) Determine the final temperature. b) Determine the work done during this process. c)...

Round your final answers to the nearest integer. A piston-cylinder device contains 4.37 kg of steam at 100°C with a quality of 60 percent. This steam undergoes two processes as follows: 1-2 Heat is transferred to the steam in a reversible manner while the temperature is held constant until the steam exists as a saturated vapor. 2-3 The steam expands in an adiabatic, reversible process until the pressure is 15 kPa. (a) Determine the heat added to the steam in...
