Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Question

Please show equations used and calculations to receive final answer. Thank you in advance!

**Example Problem 4-36E**

A piston-cylinder device contains 0.5 lbm of water initially at 120 psia and 2 ft³. Now, 200 Btu of heat is transferred to the water while its pressure is held constant. Determine the final temperature of the water. Also, show the process on a T-V diagram with respect to saturation lines.

**Explanation:**

- The problem describes a thermodynamic process involving a piston-cylinder device.
- The initial conditions are given: pressure (120 psia), volume (2 ft³), and mass of water (0.5 lbm).
- 200 Btu of heat is added to the system while maintaining constant pressure.
- The task is to find the final temperature and illustrate the process on a temperature-volume (T-V) diagram, indicating how it relates to saturation lines.

**T-V Diagram:**

- A T-V diagram plots temperature (T) on the vertical axis against specific volume (v) on the horizontal axis.
- Saturation lines indicate the phase boundaries of the substance.
- The process can be visualized as a horizontal line on the T-V diagram, showing constant pressure.

**Considerations:**

- Use steam tables or thermodynamic equations to determine properties and final temperature.
- Identify initial state and final state on diagram to understand phase change, if any.
