Pressure drop in pipes.... PRESSURE DROP CALCULATIONS Pressure drop or head loss, occurs in all piping systems because of elevation changes, turbulence caused by abrupt changes in direction, and friction within the pipe and fittings. The most common methods used to determine the head loss in fiberglass pipe are Hazen-Williams, Manning and Darcy-Weisbach equations. The suitability of each On strainer devices all data published by Hays is for a new, unclogged strainer. The variation in materials that clog a strainer makes it virtually impossible to predict pressure drops for clogged strainers. In system design it is recommended that a reasonable allowance be made for an additional restriction above that of the clean strainer.

On strainer devices all data published by Hays is for a new, unclogged strainer. The variation in materials that clog a strainer makes it virtually impossible to predict pressure drops for clogged strainers. In system design it is recommended that a reasonable allowance be made for an additional restriction above that of the clean strainer.

Pressure drop (P2) = P1 X Sp. Gravity = 1.56 X 0.80 = 1.25 psi Sample calculation Using chart 2 multiply P2 by the appropriate component factor (CF) to get P3. calculation, for example you are missing the pressure drop across the cleaner, the properties of the fluid, etc. Figure 4 The control volume determines where the conditions on the suction side of the pump can be calculated.
