Q2- One pound-mass of H2O\mathrm{H}_{2} \mathrm{O} fills a 2.29- ft 3 rigid heat exchanger at an initial pressure of 250 psia. The container is then cooled to 100F100^{\circ} \mathrm{F}. Determine the initial temperature and final pressure of the water and show the process on T-v diagram.

Studdy Solution
Illustrate the process on a T-v diagram:
- Plot the initial and final states on the T-v diagram. - Indicate the cooling process at constant volume.
The initial temperature and final pressure can be determined using the steam tables, and the process can be visualized on a T-v diagram.
