Re: How much pump is enough? How much is too much?
Conservation of energy. You put into a motor a set amount of electrical energy. You get out an amount of physical work. Those two are not equal. The rest of the input energy IS output as heat. The only discussion that can be made is for an inline pump and how much of this heat is transfered to the water.
I'm not even going into the whole moving the water creates heat discussion...just talking about the pump itself.
totally agree the dedate is how much of it is turned into heat ... and i believe this numbers are very wrong
and yeah there is friction and sound created that i agree aren't worth going into
