okay this is what I'm asking. Can wire cutters cut through a safety pin?If not. Can I heat said safety pin to cut it?
I prefer polycarbonate myself. I think the mesh visors are used by professional tree surgeons / loggers as they are more durable, they will not get scratched like polycarbonate. Edit. I asked a forestry contract cutter and he said: As a professional there is only the one choice and that’s the mesh visor. Tree sap and saw dust would soon render the polycarbonate one useless. The work was very physical and any restriction to the air flow around the face would be very unwelcome, even in the winter keeping cool was a major consideration.
You can raise it a bit. You are converting the speed of the incoming water to pressure which pushes the water up. But 15'? I doubt it. A foot or two would be my guess. That's with a fast incoming flow rate, which you don't mention. math is too complicated for me. You need an expert on fluid dynamics. If I get time, I'll look it up. But you will need the flow rate of the incoming water. If you already have the pipe, try it and see what happens.
