What two components are contained within the water column of a lineshaft turbine?

The correct components contained within the water column of a lineshaft turbine are the drive shaft and radial bearings. In a lineshaft turbine, the drive shaft extends from the motor at the surface down to the pump bowl submerged in the water column. This shaft transfers the rotational energy required to operate the impeller, which is located at the pump bowl.

Radial bearings provide the necessary support for the rotating drive shaft, allowing it to turn smoothly and efficiently while minimizing wear and friction. These bearings are crucial for the stable operation of the turbine, enabling the transfer of energy from the surface to the submerged components effectively.

Understanding this configuration is essential for recognizing how lineshaft turbines function and how forces are managed within the system.
