well done

[@lachellecarrozza5066]

Very cool!

@lachellecarrozza5066 I'm glad you liked it. It's simple, effective and cool!

Any ideas on what sort of natural materials could be used to make a model sized prototype, e.g. bamboo instead of pvc, but what instead of the tube?

[@STEMwithMrN]

@ElenaRast-g1m the honest answer is I don't know what natural material could be used in place of the plastic tubing. I've had a look for ideas online but nothing was really coming up for it. There was one suggestion to use clay, but that may be tricky to mould into the wrapping shape around the bamboo. That's a great question, though, and one I'll need to look further into as I look to improve sustainability.

جيد،،من فضلك ما المعادله الحسابيه لصنع ارخميدس توربين حقيقي للري الزراعي،،،وشكراً

[@STEMwithMrN]

The volume of flow that passes through Archimedes screws is a function of inlet depth, diameter and rotation speed of the screw. Simplified it is: Do ≈ nQ^3/7 حجم التدفق الذي يمر عبر مسامير أرخميدس هو وظيفة عمق المدخل والقطر وسرعة دوران المسمار. مبسطة هو: Do ≈ nQ^3/7

There are gaps between the clear tubing coils on your PVC pipe. If you filled these with additional coils of clear tubing, you could make your screw more efficient, but transferring roughly 3 times as much water for each turn of the plastic pipe. However, the device was not very efficient because the greater potential energy imbued to the water was wasted when it was allowed to fall to the bottom of the second container at a lower level than the surface of the water in the first container. If the second container had been at a greater height off the bench, this greater potential energy coud have been conserved - at least until Mum came home and made you pour it all down the kitchen sink, anyway!

Would love an Achedemice Screw, To fit my Highbanker Sluice for gold prospecting where can i get one? Just seams so Eco Neutral,Carbon Neutral, and its great to keep a 2000yr old system going into Domestic and commercial home for all uses,,would be better than unecologicaly unfriendly water pumps running on fossil fuels with a carbon footprint you could even make this unit solar as well as motorized battery operated.

This is a coil pump it is not a archimedes screw
