Drilling a DIY Well Using Air
This is a demonstration of airlift well drilling, a DIY method to create your own borehole. Airlift drilling is special compared to other methods because it uses an air pump (in this case a pump from an old air conditioner) to move dirt from the bottom of the well to the surface.

    Explanation of Operation of a Pump-less Suction System Operation: In this system, water suction is achieved solely by the hydrostatic pressure exerted by the weight of the water in the container. The pressure at the bottom of the container (P_tank) is greater than the pressure in the tube (P_tube) due to the elevation difference. The pressure difference (ΔP = P_tank - P_tube) pushes the water up the tube, creating flow. Compared to a system with a pump: - Advantages: - Simplicity: No pump is required, reducing cost and complexity. - Reliability: Fewer moving parts, reducing the risk of failure. - Low operating cost: No energy is required for operation. - Disadvantages: - Lower flow rate: The flow rate is limited by hydrostatic pressure, so it may be slow. - Limited lifting height: The maximum elevation difference that can be pumped is limited by hydrostatic pressure. - Dependence on slope: Operation relies on the slope of the terrain, making it unsuitable for horizontal installations. Applications: This system can be useful in situations where simplicity, reliability, and low operating cost are more important than flow rate. - Agriculture: For irrigating fields on slopes with low water demand. - Hydraulic works: For supplying small tanks or reservoirs at low elevations. - Education: For demonstrating principles of hydrostatics and fluid flow. In summary: Implementing a pump-less water suction system is feasible, but requires careful design, considering limitations in flow rate, lifting height, and dependence on slope.

    Calculation of Water Suction in a Closed Container - The container is closed: Atmospheric pressure no longer affects the interior of the container. Calculation of pressure inside the container: - The pressure (P_tank) inside the container is determined by the hydrostatic pressure of the water in the container. - P_tank = ρgh, where: - ρ = 1000 kg/m³ - g = 9.81 m/s² - h = 0.8 meters (height of water in the container) - P_tank = 1000 kg/m³ * 9.81 m/s² * 0.8 m = 7848 Pa Calculation of pressure in the tube: - The pressure (P_tube) in the tube must be less than P_tank to create suction. - For simplicity, we assume that friction losses are negligible and the velocity of the flowing water is constant. - P_tube = P_tank - ρgh, where h = 1.5 meters (length of the tube) - P_tube = 7848 Pa - 1000 kg/m³ * 9.81 m/s² * 1.5 m = -5984 Pa Conclusion: - The P_tube (-5984 Pa) is negative, which means there is a vacuum in the tube. - Therefore, water suction from the system is feasible. Notes: - In this case, suction is solely due to the hydrostatic pressure of the water in the container. - The absence of atmospheric pressure in the container allows for the creation of a vacuum in the tube, reducing the internal pressure and enabling the flow of water. - The velocity of the flowing water and the volume of water suctioned per second can be calculated using the same formulas used previously, replacing Patm with P_tank. Additional observations: - The presence of friction losses in the tube will reduce P_tube and therefore the velocity of the flowing water. - Changing the height of the water in the container will affect P_tank and consequently P_tube. - The temperature of the water can also affect its density and thus the hydrostatic pressure. Overall, water suction in a closed container is feasible, but the velocity of the flowing water and the volume suctioned depend on various factors

My issue that I'm having is that instead of the air pumping out it seems to be venting from below and having the water bubble around my drill but. I'm using a shop compressor and inputting the air with a airblow gun attachment. My drilling fluid is using bentonite. Any advice would be appreciated

    I would call this kind of pump a syphon with vacuum assist. with a larger tank it will indeed suck additional water into the tank but the tank will eventually empty to a point where the vacuum is not strong enough to raise the water needed to keep the tank full. Its a flow extender rather than a free water pump. but never the less a good idea as raising water in buckets is hard work.

The video shows that not a single drop of water are sucked from the source. The only water that comes out of this system is what you yourself manually liftet up into the bucket, nothing more. This is a siphon, not a pump. As a siphon, it can lift nothing. If you dip the output tube into a cup of water, nothing will come out of the system. You can also use a U-bend at the output. In either case, aire is prevented from entering the system from the output side and it all stops.

      @@davebloggs Siphon can not lift any water to a higher level. For a siphon to work, the water level of the source must be elevated higher than the output. To lift a body of water to a higher level you add energy to it. You can use energy from petrol, steam engin, electric motor manual work or the power in flowing water in a river. A siphon has no energy input and can not lift any water. Adding a barrel does not make the system work, it only helps a siphon to start, it is a priming device, not a continues source of lifting energy. This video shows that a siphon can not lift anything.

    While watching your demonstration is a leak pressure I hope no vacum is created, I have not tested yet but I have watch a lot of free energy I understand the mechanism how it work, the suction inlet pipe need to retain water hence no air remained inside the pipe before the outlet knob is open, When filling the drum full of water and afterward when outlet pipe knob is open the filled water flow out hence creating strong vacum pressure, hence suck water from the inlet suction pipe. # nteresting point when suction pipe retain no water the mechanism fail badly.
