percentage of open area in a screen should be the same as, or great than, the average porosity of the aquifer material. Water flows more freely through a screen with a large intake area compare to one with limited open area. The entrance velocity is low, therefore head loss for the screen is at a minimum, thus minimizing drawdown in the well.

Wedge Wire Percent Open Area Chart The percent open area of a Wedge Wire screen can be an important parameter when predicting flow capacity. The following equation can be used to calculate the percent of open area. Percent Open Area = ( Slot Opening / (Wire Width + Slot Opening)) x 100

The screen must be designed to maintain its integrity and provide the greatest amount of open area. Screen openings (holes) that are aligned in a 60-degree staggered pattern optimise open area while maintaining screen strength. This method will result in a 40 percent open area using 3.2 mm (1/8 inch) holes aligned on 4.8 mm (3/16 inch) centres.

screen whenever the wear causes the mill's capacity to drop about 15 to 20 percent or product quality begins to deterio-rate. Use a high-quality replacement screen with the same percentage of open area as the original screen and the same hole-staggering pattern. Some low-cost replacement screens have less open area (that is, more steel ...

The formulae do not indicate whether the suggested perforation is possible, they are to be used solely for calculation of the open area. The pitch dimension must in general be greater than minimum the hole size dimension + thickness of the material.

An open bottom well has only 28 square inches of surface area, while a 6" diameter well with a 10 slot screen, five feet long, will have 151 square inches of surface area, but a 30 slot screen will have over 350 square inches of open area.

"H", the "Half siz e" factor, depends on the percent of material input that is less than half the size of the wirecloth opening. The higher the percentage of small feed material the greater the screen capacity. The faster the material passes through a screen the more open area there is left to screen the remaining material.
