Alright I am planning to join 2 pvc tube that is 1" into a 1" pvc...my question is that will the flowrate be the same or should I join the 2 1" pvc into a 2" pvc instead?
Ether I am very dense at the moment or that is a very confusing way of saying what your saying.. is this for the return or for the drain of the tank? What size is the tank? what size is your pump?
joining a 1" with a 1" into a 1" will, restrict the flow to the equivalent of 1". (like you said)
joining a 1" with a 1" into a 2" will not restrict flow at all.
this is due to the fact that a 2" pipe
has four times the flow capacity of a 1",
or twice the capacity of the pair of 1".
You can safely join the 1" into the 2" with no problems.
oh I thought you said 1" + 1" = 2"
I said 1" + 1" + 1" + 1" = 2" that's why I was trying to correct you.
diameter increases the area of a circle 1:4
thus influencing throughput of the pipe to approx the same ratio.
bottom line is a 1.5" pipe would probably be sufficent
to drain off a pair of 1" but would cut it a little close for my comfort.
the 2" has twice the capacity that is needed.
