Flow and Pressure Loss in an Annulus
Flow and Pressure Loss in an Annulus
(OP)
Hello,
I was looking for an equation to calculate flow and pressure loss in an annulus. This would be similar to a shaft running in a bushing with fluid as a bearing. Typical fluid is water at 68 deg F with a bearing ID of 2.50 inches and a clearance of .020 diametrically and the length of the bearing 17.00 inches. Any equations for this would be greatly appreciated but please include referenced material.
