how ram pumps work?

Please watch human voice version of this video in here.

freaking awesome you got Stephen Hawking to narrate this video.

[jamesgetman]

Thank you for such a consice and quick explanation. The math breakdown made it make so much sense.

Can you compute the physics of the Giza Pyramid as a Ram pump? You have water going down the descending passage, a valve shoots the water to the ascending passage and gallery. The pressure tank at the relief chambers, the output at queen’s chambers and kings chambers shafts for restarting and stopping actions through those arcs at those two copper electrodes

I have used one of these pumps.  They are amazing.  They pump water 24/7 and use no electrical power.  The flow is not great but over a 24 hour period there is a substantial volume .

I would assert that the primary mechanism of the ram pump is conversion of kinetic energy rather than potential energy. Yes you need your reservoir to be above the pump (potential energy), but the key to the pump's operation is that the intake water must have some velocity so that when the waste valve closes the momentum of that mass of water forces the water along a different path even against some resistance, namely into the accumulator tank and ultimately through the outlet and uphill. If the inlet water flows too slowly it won't force itself into the tank, which means you need to tune the size and tension of the waste valve to allow the water to get up some speed before it forces the waste valve closed.

This is pretty much how boost converters work as well. It is amazing how similar the seemingly different fields of physics are!

How many meters can it pump to in elevation. I have a tribe i need to get water from the lake below to 500 meters straight up a mountain.

Shouldn't the incoming pipe be larger than the outgoing since the output trades pressure for flow?

[jsbaltes]

Between the animation and narration, you've made it crystal clear. Thx a ton. Subscribed.

Is it possible that only the current of a river to make a rampump operate?

[derekspender]

I already knew how. Now I know why. Many thanks.

[baazigaj]

what is the purpose of alteration in inlet pipe diameter to a bigger diameter?

[tomaspartl]

I wonder, would the same shut down valve do anything being installed close to the big chamber on the inlet tube?

[rich]

What makes the waste valve open? Pressure from the inlet tube would seem to keep it closed, unless you temporarily close the inlet?

[chrlschstr]

Is there a formula on how to calculate the size of the ram pump relative to the height and length of where the water is needed?

[TavernierTube]

If you close the one vent, does the other vent flow water then?

По видео очень понятно показали принцип работы, спасибо вам большое.

Best explanation so far.
Need to add sniffer valve before air tank. Because after some times the air in the tank disolves in to water and tank get fill with water. Then hammer banging starts.

[byronmasser]

Can we put spring loaded piston on air compressing unit to have a stronger pump action?

[bradwendica]

Good day, what is the meaning of RAM, is it an abbreviation of what?what mechanism is that the water goes outside the chambers, and lastly, the valves are in alternating sequence, like e.g. when one open, the other close and vice versa but not the same time close or open?thanks for you response.which determine if the accumulator valve to open and close also the diffuser valve to open and clise?
