How to find proper screen dimensions and correct slot sizes of the well screen

Diameter
Specific capacity and available drawdown indicate the productivity of a well to be expected.
If the pump is installed above the screen the rising velocity at the screen head should not exceed v = 1.75 meter/sec.
If the pump is installed below the screen in a pump sump then the screen diameter depends mainly on the pump size and the remaining annulus space between the screen and the riser pipe.
Screen length
once decided on the screen diameter the laminar flow conditions at the entrance of the screen determine the requested length. Screen length in the total height of a water bearing formation is - especially when using the con-slot screen - not necessary. The Kozeny concept of investigation for partial penetrated formation is an excellent practice to determine max. Necessary screen length.
