Okay, something is terribly amiss here.

Taking BillA's pressure drop data for the White Water alone of ~3.0m of pressure drop at 10lpm.

At 34lpm we're looking at around 35m of pressure drop for the White Water alone at a minimum.

To push 34 lpm against a pressure drop of 35m requires 195W of mechanical power to do so as an absolute physical minimum.

i.e. it's physically impossible for an 80W power-draw pump to be doing 195W of work.

Something wrong with your calculations Ivo.
