Weight-Balanced Automatic Splash Pool

Im enjoying imagining how this will look,all these people getting wet in the veld?

Sounds like fun to me,all that splashing about oh ffs.........."gross mass of the splasher"

"if a person of 80 kg gets on top of the piston" Ive witnessed such exhuberence....

better still if one person gets on another.........whilst wet of course,then onto the piston thingy,well its bound to work.......sorry bitch of a day

This sounds interesting. A,"cool-down splash in semi heated water".

Is the water that cold? I'm not exactly sure how this all would work, exactly, but, I do think it WILL work.

Can you post a sketch? Give more details?

It would be worthwhile making sure that this contraption isn't an unworkable device of the first kind. Please post a sketch for the forum to comment on.

Thanks for the replies!

The idea is still just a picture in the mind. I do think that I've got it worked out in some ways.

The freshwater inlet should be directely under the silinder so that the heated water would stay "on top" and be let into the chamber first.

What I would do is build a small model and get some pictures. I really cannot do the calculations (maybe I can but I'd rather go on trail/error basis and see what comes out.

If I use standard 35mm pvc piping as resevoir, what does the lenght have to be to hold 200 liters of water?

Leon, hope yer weekend is great!

Your description is pretty fuzzy, and the logic of the weight/bouyancy actuated valves is unnecessarily convoluted. Better to use a tank with conventional valves to fill and empty it thereby minimizing the chance of malfunctions spilling precious water into the soil.

Black pvc pipe laid out on the ground will indeed function as a solar water heater. Insulate under it and put a transparent cover over it to increase efficiency. Just over a meter of 35mm (id) pipe will contain a liter of water, so you'd need .6 km to hold your target amount. Under direct sunlight you could get too hot a product for your purpose - perhaps steam, so be careful and start experimenting with less length and/or bigger diameter pipe.
