SNORGY...wait...now I am a little confused, after reading your last post.
We agreed earlier that throttling a pump, and a restriction orifice both achieve the same thing...reducing flow on the downstream side. This is evidenced by moving left along the x-axis on a pump performance curve...
I'm having a hard time understanding the comparison between pump throttling and orifice restrictions. What I mean by this is:
1.) When throttling the discharge of a pump, you are restricting flow. As you restrict this flow, you are INCREASING the pressure head. This is evidenced by moving...
