Water is chilled by brine in a counter-current heat exchanger. If the flow rate of the brine is 2 kg/s and that of the water is 1 kg/s, estimate the temperature to which the water is cooled if the brine enters at -4°C and leaves at 12°C. The water enters the heat exchanger at 28°C. If the heat transfer surface area of the heat exchanger is 5.50m^2, determine the overall heat transfer coefficient. Take the mean heat capacity of brine and water to be 3.4 kJ kg^-1 K^-1, and 4.2 kJ kg^-1 K^-1 respectively.

I need help with this asap please. Thank you very much. I will tag anyone who answers as brainliest.​

Answer:The area of heat exchanger

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
