    Can anyone direct me to a table or calculation regarding flow of water, impelled only by gravity, through a pipe or channel? I would like to determine the nominal flow rate of water flowing through a 1" (I.D.) pipe, with no other pressure than just gravity. The vertical drop from the tank is...
