Barney12 Posted April 28, 2017 Share Posted April 28, 2017 I have a question: If you have a 100m loop of water (in a water pipe) in a sealed circulating loop (with no air)....... If said circuit is going uphill (but of course what goes up must go down!) rather than level. Does it require more energy to circulate? In other words does it require a bigger pump?

ProDave Posted April 28, 2017 Share Posted April 28, 2017 No It will syphon over the top bit. Link to comment Share on other sites More sharing options...
PeterW Posted April 28, 2017 Share Posted April 28, 2017 No - the falling water will create pressure that will be equal to the force required to lift the water ... Link to comment Share on other sites More sharing options...
Nickfromwales Posted April 28, 2017 Share Posted April 28, 2017 That's why pumps are actually referred to as 'circulators' . Link to comment Share on other sites More sharing options...
Barney12 Posted April 28, 2017 Author Share Posted April 28, 2017 Thanks guys. I had a minor panic moment after we started to dig the geothermal trench downhill which wasn't the original plan! Link to comment Share on other sites More sharing options...
