Hello, i have a question about the design of fountain pump. Here's the problem: By estimating the height of the fountain's central (the highest one) and other quantities, determine weather it would be better to have a pump just below the water's surface or at the bottom of the lake. What kind of pump do you recommend?

Note: It can be considered as a big fountain with highest water jet of about 10 meters.

Based on the information on this site: http://www.pumpfundamentals.com/tut...tm#ener...

I think the pump should be placed just below the surface of the water, so there is a big depth of water underneath to provide enough elevation energy. Haven't done the calculation yet, so it's just my assumption.

Thank you very much in advance.
