Thanks again for your advice. The purpose of the lower tank is to act as a sump/filter for the higher one, so effectively I really only need to know roughly how well it is doing, and of course there is the academic curiosity (witch I must admit would still like to see the formula even if I never...

Thanks for your advice I will do as you suggest . In my experiment I felt there mite be inaccuracies some that would flatter the LPH and some that would diminish the LPH figures e.g. the Ventura pipe that normally sucks air into the outflow stream was acting as a pressure escape valve so...

Essentially my problem is that I want to know how much water is being delivered from a lower tank to a higher one. I can be confident of the static height (1.1m) but what I’m not able to be sure of is how much water is being delivered at lower elevations probably 0.9m. If I knew the formula to...

Homework Statement 800L/h rated pump 12.6mm outflow pipe. Static head height 1.10m There seem to be no undue turbulence in the flow. Environmental pressure is just atmospheric (1bar) 2. Homework Equations Unknown The Attempt at a Solution I have done the physical experiments which is how...
