How well does centrifugal force project liquid?

Physics Asked by fodder feline on May 16, 2021

Apparently, high-pressure impact sprinklers, used to water fields, have pumps that work at between 25 and 60 psi. This lead me to wonder: If I swing a stick with a hose attached to the end of it, and generate that much force, would it project the water with the same force?

Example: I calculated a 10 foot radius with a tangential velocity of 100mph. I calculated the mass as 1 point, for the end of the stick and the head of the hose. The result came out as 111 lbf, which (correct me if I’m mistaken) can directly be converted to 111 psi.

At that rate, isn’t the implication that you could technically generate the same effect as the sprinkler with centrifugal force (or centripetal force, but I used a centrifugal formula)? I ask, as I was considering it as an element for a story.

Thank you.
