Difference Between a water wheel and a water turbine?

Click For Summary
SUMMARY

The primary distinction between a water wheel and a water turbine lies in their applications; a water wheel typically powers mechanical systems, while a water turbine is designed to generate electricity. Water wheels can be classified into undershot and overshot types, whereas turbines, although fundamentally different in design, can also be utilized for similar functions. Turbines are generally submerged but can operate with water flowing over or under their hub. Both devices can be employed to generate electricity or drive mechanical systems such as pumps or boats.

Is the difference between a water wheel and a water turbine the fact that a water wheel is used to power a mechanical system where as a water turbine is connected to a generator to produce electricity? I understand that you can get undershot and overshot water wheels but do these also apply to water turbines?

A turbine is physically a different beastie to a wheel.
Google for the images and look.

Turbines are usually immersed - but don't have to be. If they are not immersed, then you can have the water pass over or under the hub.

Either can be used to make electricity or drive some other mechanical contrivance.
Either can be driven to push water as in a pump or a boat.
