pump water at rate of 10 L/s through diameter 10cm suction pipe.
Calculate the maximum height the pump suction is to be installed if net
suction head is 4.0m and vapor pressure of water is 2.34kPa at 20C, 1atm

My Laars Lite Pool Heater Was Installed With The Flue Resting Directly On The Heat Exchanger. Is This Correct?

Other diagrams I’ve seen either show a ‘flue collector’ that the flue rests on, holding it several inches above teh heat exchanger, of include a tab on the flue that I assume might keep the bottom of the flue opening several inches above the exchanger? This is a laars lite 175 model. I’ve just had to replace the exchanger and wonder if this may be part of the reason that it began leaking after only 6 years.
