Thx for answering firstly!
That's weird. The reference said:"An expansion of the flow area causes the liquid’s velocity to decrease to more than when it entered the pump" and you said "The velocity leaving the pump is higher than the pump intake because of the smaller discharge on the...
I'm trying to understand this paragraph:
"After the liquid leaves the impeller, but before exiting the pump, the final transformation of energy occurs in a diffusion process. An expansion of the flow area causes the liquid’s velocity to decrease to more than when it entered the pump, but well...
