How Do You Calculate The Power Of A Centrifugal Pump From Head And Discharge?

Posted by admin on January 29, 2010 under Fluid Mechanics | Read the First Comment

The power is proportional to the cube of the pump speed.

You will need to create the pump curves for your pump, or the vendor may have one you can use, or adapt to your fluid with a density coefficient.
