I'm assuming that you're not trying to imply that the pump's behavior does not correspond to it's curve.
I simply used a bucket of water at the inlet. Granted that there was a 1 foot rise, but I honestly expected the water to shoot up 15 feet, not 10. I have to revisit that test sometime, and see how I can get it right
. I know that my previous calculations were wrong.
