It is very helpful to think in terms of power associated with the movement of a fluid.

You can use this relationship to quickly estimate how much power should be needed in a system, how much power is being lost due to friction, etc. 

But it is also a simple principle that should be ingrained into anyone who wants to reduce energy consumption in fluid systems. 

 

It is very important to not just understand, but keep these relationships in the forefront when considering the effective use of energy in pumping systems. They are simple but powerful.

 

Everything else just details.
