Answer #1

Answer: 5

b) There is heat loss from the pump to the surrounding.

Because the entropy generation cannot be negative and hence the entropy change has negative value due to heat loss because as per sign convention the heat loss from the system is negative.

thankyou.....please upvote it ...
