Explanation:
Equation for energy balance will be as follows.
Hence,
Therefore, we will calculate the final temperature as follows.
= 868.03 R
Now, we will calculate the mass as follows.
m =
=
= 1.031 lbm
Hence,
Putting the values into the above equation as follows.
= 655.2 Btu
Thus, we can conclude that work done by paddle wheel is 655.2 Btu.
