Another "myth to kill"??.....what makes it go???

Area is implicit of course.

I will say yes. Of course pressure is needed to overcome the load. If I remember right, a pumps job is to produce flow primarily, and pressure is secondary.
Pressure that has no flow= no work, but potential work.

If the river is flowing the Ram pump may be pumping as well as waterwheels turning various equipment.

But mainly it seems to be the state of the energy and it's application.:thumbsup:

How can objects (a load) move where there is no "flow" available???

They can't.

edit- Back to the original question. Flow alone can make it go as long as as there is no resistance or load.

Parasitic, weight, and leakage.(or a damned good magician!)

yes objects can move with out flow.....it happens all the time...my wheel barrel moves without hydraulic flow....and so do everything else that moves from just a force....
read Newtons first law again.....only force is required to move an object....

If no flow, then no go. You could have pressure, you could have volume, but if the fluid is not moving, you have a static situation, such as an accumulator. The potential for work is there. A weighted load is another way to push fluid, and could exceed the pressure of a pump. When you ram that bucket into a dirt pile or a stump, the back pressure could exceed the pressure rating of any component in the hyd system.

I thought we were talking hydraulics here.

{ Wheel barrel } ?

Depends on how "Slippery the Slope" is!:thumbsup:
