just to get things clear for me.
we are talking about a closed water loop. my sciense teacher used to tell me that pressure is the same in all directions, that's why a boat can float. Right?
every pump has a maximum pressure it can produce. the 1250 a bit more then a L20 (head for the 1250 2.5 meters, for the L20 2 meters)
If you would restrict (or under presure) the water inlet of the pump, the pressure would drop. If you would place pressure on the water inlet, the pressure build up would increase. That's why the pumps in serial should perform better.
Would there be any diference in pressure if you would squeeze the water through a 8 mm hole or trought a 20 mm hole?
In an open system, sure. In a closed loop I'm not sure.
Sinse there goes less water through the 8 mm hole, the pump also gets less water, and therefore should perform less. The pressure biuldup will be faster, that's for sure.
With a 20 mm hole, it can move almost all of it's pressure. A cosequesnse will be that the water in a closed loop, entering the inlet of the pump would also be in a pressure state, or at least less restrictend. so, the pump would be able to give more pressure.
The presure build up would take a bit longer, but should end up equal or more to the pump who squeezes the water through the 8 mm hole.
This is only about the pressure build.
Next part is that we will be losing pressure(?) since we are using hoses, radiators and water blocks. The friction will course a pressure drop.
This will be more if we would place all blocks in a serial loop. (according to some posts, you will lose 85% flow, compared to the pumps specifications. a 1200L pump will give only 150L of flow in a water cooling setup)
If we would make a paralel loop, the friction will be less.
So the question here is:
Where is the break point?
The White Water has one inlet, and 2 outlets, giving less pressure in the waterblock, but a better flow.
If only pressure would be the key, I should turn my setup arround, make the outlets an inlet, and place my two pumps there.
pump-pump-split-2 inlets-1 outlet.
This would give the most pressure on the inner side of the WW.
Please help me out here!
