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.

Pressure drop curves are based on water flow with standard screens. See page 16 for correction factors to be used with other fluids and/or screen openings. 2.

Pressure drop due to straight pipe is calculated using equation (1). TABLE V

Select a strainer of the same nominal size as that of the piping to which it will be connected (nominal size of piping = nominal size of strainer). Please remember that using a strainer of a smaller nominal size increases the pressure loss of the strainer and may disable it from keeping specified pressure at вЂ¦ a clean basket from curve on appropriate Pressure Drop Chart in the Technical Data Section (flanged end). At 1000 GPM of water the pressure drop is .4psi. As described above the multiplying factor for a 50% clogged basket is 2. The pressure drop is then .4psi x 2 = .8psi.
