How High Can a Gravity-Fed Water Fountain Shoot?

[brandy leshee]

My son is wanting to build a gravity fed water fountain that shoots 20 feet up in the air for his science fair project only problem is neither one of us knows where to start or what to use to build this. Was hoping someone would help?




Thank you

Welcome to FP.

Have you had a look at real-life gravity-fed water fountains?

Note: if the only energy source is gravity, then your reservoir will have to be more than 20' above the ground. Though I suppose you could use a stream. Start with a clear description of what you want to achieve and the constraints that must be followed.

Since this is a science fair - you really want to try for an experiment: what are you testing?
