Headloss through filter pack
Headloss through filter pack
(OP)
Need help figuring headloss through a groundwater well filter pack. I'm thinking it would be something like headloss through a sand filter but I can't find a formula that quite fits.

Your question made me remember I had the same question several years ago. I had a bright engineer working with me and we decided to build a model of the filter pack/well in the office and measure the headloss as a function of pumping rate. It worked great and accurately predicted the response of the actual well in the field.

It was a long time ago and I don't remember the details. We built an exact replica of the well on a barrel added a pump and measured the headloss. Pretty basic but instructive.
