Pressure through pipe orifice
Pressure through pipe orifice
(OP)
Hello,
I am looked for resistance coef (k) values for calculating pressure of a hole in the wall of a pipe. Is this the same as k values for an orifice in a pipe? This is for a design of cooling spray around a shaft. The cooling water will be directed through a circular pipe around the shaft with orifice holes in the pipe spraying the water into the shaft bearing. I need to calculate the pressure through the orifice. Any help is appretiated.
Thanks
Travis

RE: Pressure through pipe orifice
If the total flow thru the holes gives significant pressure drop along the distributor pipe, you'll have to iterate to get a good supply pressure for the orifices.
Good luck,
