Temperature Drop across pipe
Temperature Drop across pipe
(OP)
All,
We have a gas at 280F. This gas is sent to Amine unit for further polishing.If the amine unit is approx 2 miles downstream would there be any temperature drop
Any help will be appreciated

RE: Temperature Drop across pipe
My hot water heater is only 40 ft from my shower and there's a temperature drop.

Insulation.
Velocity
Gas Properties
Ambient conditions
To name a few.

By the way, older homes are built with copper water piping, which is a pretty good conductor, so don't expect as dramatic a drop as from your hot water tank to your shower.

Thanks for your assistance,
Is there a theorotical method by which I could be able to calculate the temperature drop across the length of the pipe.
Any suggestions welcome

That said, your piping insulation, fluid flow rate, solar load and ambient air also need to be factored in. Overall, there's no simple closed-form solution, but there are thermal analysis programs that could probably do the numerical analysis.
You can potentially set up a lumped parameter model of the pipe and at least get a reasonable swag.

Take a look at

There's a link to a spreadsheet at the bottom that will help with your question.

If the pipe is relatively well insulated, then the process follows that of a Fanno line.

You might wanna look on www.tycothermal.com (a.o. supplier of Raychem heat tracing) as well.

Your questions are very "basic". How will you document and QA any calculation based on what you can read here?
Best regards
