I know that pressure drop is cumulative. Hence the pressure going into the first component is higher than the next component. Makes sense doesnt it. If this isnt true then please explain because as far as I know that is the way physics operates.

I know that flow rate is constant going in and out of the block, and in the entire loop itself.

The pressure of the water going into the pump is much much less than the water being pushed out of the pump. For this reason the pressure in the loop is "renewed" (spelling) as it exits the pump.

At a certain point of a closed loop there is less backpressure and more negative pressure (vacuum pressure) pushing the water through the loop. At what point that is, is entirely dependent on the lenght of the loop and the pump as well as components in loop.. But still there is this point. For myself I dont reach this point as the head on my pump is 14ft and the water in the loop doesnt travel 14 (atleast i dont think it does) feet till it reaches the intake on the pump. Anyway the point of this is that in a closed loop like our water cooling loops the pressure does drop....
