🎯 Key Takeaways for quick navigation: 00:00 Water *moves by gravity without electricity, governed by physics.* 00:39 Water *pressure is 1 psi for every 2.5 ft of head. In metric, 1 meter equals 1/10th of one bar.* 01:06 In *flat landscapes, flood or furrow irrigation can use low-pressure gravity.* 01:35 For *pipes and irrigation systems, height above the point of use determines pressure.* 02:02 Drip *irrigation needs a minimum of 10 psi, requiring water storage at least 25 ft above.* 02:55 Sprinkler *systems require at least 30 psi, needing water storage 75 ft above the outlets.* 03:36 Check *product specs for minimum and maximum pressures; consider elevation and friction loss.* 04:04 Friction *loss in pipes affects pressure at the outlet; use charts to determine friction loss.* 04:59 Float *valves maintain a steady water level in troughs or tanks, ensuring a constant water supply.* 06:07 Siphons *use gravity to move water over obstacles without the need for fuel or electricity.* 07:04 In *rainwater harvesting, a "wet system" allows water to flow down, up, and into a tank.* 07:31 Gravity *irrigation principles can transform landscapes sustainably without the need for external power.* Made with HARPA AI

@SimonHaestoe 6 ай бұрын

Dude, you have no idea how lucky we are to get this for free. Sure, not everything that can be said on the subject will be said in 8 min but sometimes constraints are exactly what we need. And that's permaculture - we observe and interact with what we have. Just imagine what this level of education would have cost 30 years ago. There were books around, yes, but WHO teaches as clearly as Andrew does? There are other awesome permaculture ppl, and growers, but it gets fluffy or they are insecure and have to be witty or use music and just distracts from teaching. Feels awesome that a UNIVERSITY (OSU) can be what a university should be - education, not just politics 👏⚡

This is where trying to directly communicate with the creators of these channels is important. Another good rainwater harvesting resource is Brad Lancaster's Rainwater Harvesting in Drylands and Beyond. Haven't seen his newest edition, so it may be worthwhile to check out Mark Shepard's book on harvesting rainwater for larger scale farming. (Sorry, forget the name). Mark also wrote on restoration ag, another good read for upscaling /upsizing permaculture ag practices while simplifying them as well.

It would do well for parks and forest services as well as farmers, ranchers, and townies to adopt rainwater harvesting methods using (primarily) onsite materials. The West and Midwest, as well as internationally critical areas need these methods. This is important to build resiliency for now and in the future.

Wow these videos never disappoint! Amazing work once again: not only are they so informational and well made but they also put me in such a good mood because they give concrete ways to take action in the face of climate change and subsequent newly arising hardships: I really believe that if we want to get some change going we have to feel empowered and the rhetoric surrounding climate change cannot just be "do less of something" because as humans we are not very good at that; but in your videos the rhetoric becomes more of a "there are these following things we can do better than in the past: let's construct in this more efficient way, let's do that in this better way" which is a type of message that is very motivating and positive and that as humans we respond very well to :) Also this video is very empowering because it gives people the ability to do some back-of-the-envelope calculations even if they are not engineers or have some similar degree: quantifying something really helps in not building things that won't work anyway and this way it becomes easier for someone to quantify even a small diy project.

You don't need 10 PSI for drip irrigation. Flag emitters can work even with less than 1 psi. I know, I have been using flag drip emitters with an IBC rain tank raised up on cinder blocks through 3/4 inch hose and 1/2 inch drip lines 50 to 100 feet long. Depending on the water level in the tank and ignoring friction my pressure would be roughly between .7 and 2.3 psi, averaging around 1.5 psi. You have to let the drip run longer than if it were at 10 psi, but that's not really a problem.

Wells are obviously a luxury, but the easiest way to bring water to the individual is through rainwater harvesting. When my family goes camping we use a julka ran in solar and batteries for our pressure. I run stream and pond water through a Sawyer water filter for drinking water. It's cheap and simple. Wells are expensive and deplete the ground water if water storing techniques are not being used.

@@vivalaleta In a cold climate the water will need to be drained. But the water in the 'wet' part of the system will be displaced with each new rainfall. So in a climate with long dry spells, then I could see the water becoming stagnant. Although a proper system will have screens to keep out any insects and rodents.
