I have a pipe that carries a fluid. The pipe is drawing heat from a source and is transferring to the fluid which is being circulated. I need to know the exit temperature of the fluid.
Known variables are:
1. Inlet temperature of the fluid
2. Inlet pressure of the fluid
3. Outlet pressure of the fluid
4. Constant mass flow rate
5. Thermal properties of the pipe
6. Temperature of the pipe
Goal:
Exit temperature of the fluid
How to proceed with this question?
Length of the pipe and heat capacity of the liquid are necessary -as minimum.
Hi,
Indeed you can solve the problem under investigation by performing CFD simulation as suggested by Dr. Rani. This approach which requires ressources and skills is usually used when a detailed and finest solution is desired.
Now if, the objective consists in predicting the fluid's temperature at the outlet of a pipe, analytical solutions have been already developped for specific cases that you may find in any heat transfer texbook such as Incropera and Dewitt. However, you have to make assumptions to simplify the problem and be able to use the existing solutions. Good luck!
Hope this paper helps you
