Answer:
The area of heat exchanger

Step-by-step explanation:
Given that
Brine heated from 10°C to 35°C and water cools from 60°C to 45°C.

Lets take these are act as counter flow heat exchanger.
So

As we know that

Here


LMTD=29.7°C.

for water
0.3 x 4.187 x 15 = 950 x A x 29.7

So the area of heat exchanger
