Will this water pump work? 2.0 Answered
I have updated my design for a simple water pump with the comments on my last one (https://www.instructables.com/answers/Will-this-water-pump-work/) in mind. It's thought to be hand- or windpowered and lift water 30-50 cm (1-2 feet i suppose). The cylinder will be about 10 cm (4 inch) across and the piston head 2 cm (1 inch) thick. The outlet is far too small in the picture.
