Question

Any help would be great!!

A rigid tank with total volume of 0.05 m3 contains a movable piston separating the vessel into two compartments, each containing 25g of water, as shown in Figure 2. Initially, both compartments are at the same temperature, with A at a pressure of 100 kPa and a volume of 0.04375 m3. The weight of the piston applies a pressure of 50 kPa on the water in B. The water in B is then heated until it becomes a saturated vapor at a pressure of 200 kPa, while the water in A is cooled to maintain its initial temperature. Find the change in temperature of the water in B and its final volume.

Explanation / Answer

This question can be done with the help of thermodynamic tables for saturated water which should be supplied with question or its data relevent to this question.

when you know the volume of water and its mass, you can calculate its specific volume. At a given Pressure:

using the 50 kPa pressure in 1st part you can find initial temperature of B and using 200 kPa you can find final temperature in B and its specific volume and then its volume (specific volume*mass).

Also you have to understand that temperature and pressure of A remains the same according this question, it just goes from saturated vapour part to saturated water part.
