ANSWER:
Solution 100 HP
Step 1 of 4
We have to find the final temperature and the amount of heat transfer in the process.
The specific volume of 1 kg water at 20°C with volume 0.1 m3 is given by
Since, the piston is locked there is no volume change.
Hence, the specific volume of water after heating it to saturated vapor is same as .
