WOW Can a Siphon Increase Head Pressure for a Ram Pump?

Will the ram pump have more pressure if you introduce more head pressure by siphon? In this video I test a normal 5 foot drop of head pressure and then increase the head pressure by siphoning water up another 3 feet. The results are interesting for sure. I am going to run this test again to see if the water lift is higher or if this test only works for pressure. (It would be amazing if this simple trick can increase the height of the water lift.

I asked this exact question on practical engineerings channel, so glad to see someone tested it. Thanks!

[hangomamusic]

Wow.. Fresh content... Can't believe this was posted an hour ago.. Thanks

I built a similar system using siphon suck water out of pond then connect to ram pump. what I found there are air accumulation in high-lift siphon caused ram pump to stop working after few hours. but siphon still running with bubble inside, I am thinking to add a stand pipe between siphon and drive pipe and make siphon input slightly higher than drive pipe, so to create the air free for drive pipe, hope this will solve my problem.

You need to replicate the first test, because th 45psi was with the cracked fitting.

I do like Ur pump design. Simple and effective.

Very interesting...sounds like a job for the "world's smallest ram pump"!

[reyandrade]

Sir of all your ram pumps assembled which one deliver the most outflow? May i know the specs so that i can replicate it here in the Philippines. Thanks and more great videos from you not just on ram pumps.

[jpowe]

Very interesting results. Have you ever considered writing an ebook about everything to know about ram pumps? You seem to be the leading expert when it comes to ram pumps and it seems like another way that you could monetize this channel.

I've used bridge siphons in aquaponics system to maintain water levels in two tanks. I had to add a separate water tank because my fish tank water level would drop too low when four media beds filled at the same time prior to bell siphons returning the water to the fish tank. One thing that helped was to make certain all air is removed from the siphon. Over time, it would stop working because air got trapped in the siphon. I never could figure out where the air came from. Perhaps DO (dissolved oxygen) separated from the water. IMHO A working siphon lifts the water and with more head height, a RAM Pump will develop more pressure. If this theory is true, a ram pump could be setup on flat land! Are you thinking what I'm thinking? Free Energy!

nice can't wait for the results. thank you for sharing.

[edsautter]

Testing results will be greater as you have a higher head at the top of the apex of the syphon. Good test to show this. Seems you did a similar process at the neighbors pond some years ago. That was when you pulled water over the dam if memory serves me. Thanks again for another ram pump video. I'm going to get mine running again this year and this is spurring me on.

Love your ram pump experiments. Keep them coming!

According to fluid dynamics, you cannot raise pressure though siphon. Water pressure at the raised section will be lower than source pressure. Pressure at the ram pump will be the same whether the pipe is raised or not.

[KillaHawg]

I’m not sure why that experiment worked. The increase in pressure on the back end of the “siphon lift” should be offset by the decrease in pressure on the front end. I love your practical and informative videos.

[lukeyetsterjones]

rather than a straight siphon have you considered a higher output system such as those in the "learn for life" free energy water pump videos?

[daveparker]

The resulting pressures should be the same once you retest without the cracked fitting on both tests. The net gain is zero because the height of the bucket is the same. Whatever you “gain” by putting the hose over the stairs is lost because the water has to first travel up the hose to the new height. Not sure if I’m making sense or not. Looking forward to the retest as the proof is in the pudding.

[bobmulder]

Why not use a series of pumps each one would deliver to a small tank at its delivery hight then the next pump would feed off it and lift it a multiple of that one So fist one lifts 10 feet above the source on a stand then the next feeds off the 10 foot drop to lift it much higher

[patrickhoffmann]

Nice test! And I have seen you pulley system which you mentioned in the email. I suppose that can be used for a lot more fun testing! ;-)
I also have two commends on that test:
1. You have measured the maximum pressure after 1 Min. of operation but not the flow rate. There could be indeed a change in the maximum pressure if you add this extra height with the siphoning. To my opinion, the maximum reachable pressure depends (among others) on the speed to which the water is accelerated in the Drive Pipe before the Waste Valve closes. That top speed depends also on the path and not only on the hight (see Brachistochrone curve). But that should not affect the flow rate, because that is governed by the laws of Energy Conservation. And you do not add additional energy to the system when you siphon the Drive Pipe water over some additional height.
2. You should also avoid siphoning when measuring the Delivery Height. If you just lift the middle of the hose to a certain height and leave the open end on the ground, then a siphoning effect may start when the water has reached the highest point in the hose and flows down to the open end on the ground. That will not necessarily be the case (e.g. if the flow rate is low and the diameter of the hose is large enough so that the water just flows down in a small stream without filling the hose), but might be an issue. Hence it would be better to either lift the measuring cup together with the hose (e.g. put the open end of the hose into a bucket, then lift the bucket to a certain height, then let it run for a certain time, then lower it and measure the pumped amount of water) or have the water trickle into a second hose/funnel at the highest point. I must admit that this sounds a little complicated.
Greetings (and also apologies for the large length of this commend / math/physics is complicated ...)

I have a high head pressure issue I'm trying to design around. What needs to be changed to make it work? Im going lift water to 250ft into the elevated holding tank.

[larryreaves]

What about a siphon on the waste valve that runs further down the hill? Wouldn't that create more velocity to add pressure to the output?
