Hi all,

I am designing a heat exchanger for my final year design project. The coolant i am using is liquid brine, how am i to calculate the outlet temperature if i assume the inlet temperature to be ambient?


Thanks

First what is the brine solution?
What is the brine percentage?

Seach thermal properties of the brine solution.

Also, ask yourself what properties are critical for a heat exchanger calculations. 

Where is the brine solution coming from?
Why did you choose a brines solution?
Is the concentration consistent?
Is it a closed system?
What is the temperature of the stream you are heating or cooling?
Many of these answers will also help choose material of construction.

Thank you for your reply. Firstly I will research on the thermal properties and see from there.

Thanks again

Perry's Chemical Engineers Handbook has a good reference source for the physical properties of brine solution.

Depending on the result of the previous replies...
the type of model u want to use will also determine
how your calculation will occur. i.e is it going to be tubular,
concentric, or shell and tube... cross or counter flow.. of which there
are some formulas for...

You can also find a clue from the process heat transfer by DQ kern, I have taken help from this book, while designing a reboiler.
