Hi bạn. Làm sao để tính đường kính lớn, để sau khi cắt vừa với ống bao bên ngoài vậy ạ? Cụ thể là mình làm lõi 27, vỏ ngoài 90. Có làm theo công thức của bạn mà ko đc😭
iirc Archimedes screw is not the one fully submerged on water but only the end of that tube and must be raised or elevated at an angle. otherwise it will just be an auger
What this is--- auger --- not archimedes screw. The spiral baffles should be attached to the outside pipe also. Then the entire assembly would turn to form archimedes screw
