Heat Generated in circular tube?

Heat Generated in circular tube?

(OP)
Hi,

I am loooking to calculate the heat generated in a circular tube due to friction.

I have an equation here but can't find a reference for it:

Btu/Hr = PSI X GPM X Diameter

Does anyone know where I could find this equation?

Thanks

Hi,

I found it in the fluid power data book in the fluid power formulas.

It is the heat equivalent of fluid power equation.

Thanks!

RE: Heat Generated in circular tube?

Hi,

The heat generated by friction in a liquid would be that of the pressure drop as following:

P = Vs * dp

P = Generated heat [kW]
Vs = Volume flow [m3/s]
dp = Pressure drop [kPa]



To calculate pressure drop, search the forum or read http://4wings.com/lib/files/velocity_and_pressure_drop_in_pipes.pdf

That makes a lot of sense and that's what I thought initially!

Thanks Drexl!!
