Tim Schultz  asked the Naked Scientists:
   
Chris: I am trying to heat our pool using the the existing circulation system.
 
I have attached a 1" hose from one of the outlets in our swimming pool circulation system. I ran about 100' of 1" pipe along side the pool and the temperature rose about 3degrees f. the water is coming out at the top of the water level at 8 l per minute. I want to add 200' more to the system but am afraid the back pressure will reduce the flow rate. Will lowering the pipe 4 feet to the bottom of the pool create more flow and vacuum pressure even though it is being submerged in the 4 feet of water?
 
Tim

What do you think?

I'd agree with Steve. The reason it won't make any difference is because the effect of the downhill flow will be cancelled out by the effect of the uphill flow.
