Question:

Flow from a tank 11' above ground, 8' diam x 13' long, 6& discharge pipe, gravity fed?

A firefighter friend of mine has this question. If they had a tank 8'diam x 13' long with a 6 diam line from it down to the ground, what would the flow be when they open the valve? The bottom of the tank would be 11' off the ground, it is a gravity fed system. Assume two 90s for fittings, standard cs pipe (if required), I don't need it to the thousandth of a gpm :)a) What is the flow (gpm) from the tank when full?b) What is the flow (gpm) from the tank with 1 of level?c) What is the time to empty the tank completely (starting from full)?Thanks all.

Answer:

sounds like you might be wondering if the friend you were texting is real or not.
because we are INSIDE the space time universe . we can only do mathematical Imagination of what it might really be Einstein develops concepts that are based on very advanced mathematics and imagination dimensions are not just what we see but mathematical varialbes like ( x,y, z, t, p, q, r ) math equations can have as many dimensions as the mathemetician needs for the problem there are some people who have theories that require 11 dimesnions to describe the universe. that does NOT mean the theory is correct only that IF it is a good description of what Really is, then it takes 11 variables to describe it it is almost impossible for most people to understand ( including me) they would be no more than Harry Potter magic EXCEPT he makes very specific predictions about the orbit of Mercury, the light from distant stars that pass close to the sun ( we can only see them during and eclipse when the bright sun is blocked) and an explanation of energy and mass that does predict Atomic bombs there is a saying: Mass tells space how to bend and bent space tells Mass how to move sounds cute but what does it mean?
use compression or push fit fittings with stainless steel braided flexible connectorsmuch easier and way less work
