PUMP GUY MAILBAG: Liquid Force

The difference between ‘Head’ and ‘Pressure’ in pumping systems
Larry Bachus
One Comment

I have a question after reading your previous article in Flow Control (“Rocket Science,” July 2014, page 40). Can you explain further how the head will not be affected by changing the liquid handled?
