Jet Pump (Single Pipe)

Hello all!

I am going through the material and having a tad bit of trouble understanding how the single pipe jet pump is able to generate suction. I understand the double pipe and how it generates suction through the Venturi effect. I just am lost as to how the inner workings of a single pipe works.

In short, can anyone direct me to a diagram / illustration / detailed step process on how the single pipe process works? Thanks in advance!

Actually, the double pipe jet pump system push the water from the well while the single pipe system get the water from the well through suction.

A single pipe jet pump simply sucks the water up.
These are typically shallow well only 25’ and only pump 4 - 5 GPM.
