How is a submersible pump and motor typically positioned within a well?

Suspended from a cable above the water
Placed on the surface of the well
Suspended by pipe, placed near the bottom of the well
Installed at the water surface level

The correct answer is: Suspended by pipe, placed near the bottom of the well

A submersible pump and motor is designed to operate underwater and is typically positioned near the bottom of the well for effective water extraction. This placement allows the pump to draw water efficiently from the aquifer, utilizing the natural pressure of the water column above it. By being suspended by pipe, the motor is protected from exposure to the elements, and it avoids cavitation, which can occur if the pump is located above the water level. Installing the pump at this depth also helps prevent issues related to sediment and debris that could clog the intake if the pump were located too close to the surface. Overall, this configuration maximizes the pump's efficiency and longevity.
