Friction in Exhaust Stack
Friction in Exhaust Stack
(OP)
Exhaust stack have friction chart like the one I attached.
How about for higher temperature? If there is not chart available, what equation should be used?

Most of drop is the loss of velocity head at the exit. Calculable from various compressible gas formulas
You can always make your own table for this method and see how it compares against your published table.
Good luck.

Click on the link I posted below.
Scroll all the way down to near the end of the linked article, to "Air Density Correction." There you will see how to CORRECT the friction you calculated at Standard Conditions, to the friction you will have at the higher temperature and altitude.
