I know it's out there but I'm pressed for time and too lazy to go looking for it. :)
Here's what I need.
I'm running a drip system from the faucet in my garage to a second story balcony. My genius builder didn't think to install a faucet out there. Anyway, what I have is some 1/4" tubing that goes directly from the faucet (on a timer) up the length of the garage door, across the length of the garage door, down the length of the garage door (two car garage), out the garage to a patch of dirt, up a tree that brushes against my condo, exteneded along a branch, finally entering my balcony, up two a flower bed - whew......okay...Now, I have enough pressure to water two flowerbeds - 4 drip sprinklers. I want to add three more pots and know that i won't have the water pressure to do so.
The total distance that the tubing covers is around 50'-60'.
I have issues here with the homeowners association so I have to keep things as stealth as possible - that's why I chose to use the 1/4" instead of 1/2".
Soooooo...now I was thinking of re-tubing the lengths on the inside of the garage - up, across, and down with the 1/2" tubing. Is this going to give me more pressure?
I guess what I'm looking for here is someone kind enough to help me with some calculations.
Something like:
"water pressure" is directly proportional to "x length of tubing" having an "inside diameter of x"
I'd like to know if I gain anything by "cutting down" the distance that I'm using the 1/4" tubing and instead replacing it with the 1/2" tubing. The total length of all tubing with still be the same - still
50'-60'.
Say for example I now have:
A. 50 feet of 1/4" tubing from water source to flower bed and that I get a water presure reading of X.
B. If I use 20' feet of 1/2" and 30' of 1/4" should my water pressure increase? If so, by how much?
One more question:
C. If I use 20' feet of 1/2" then go to a 1' section of 1/4" then back to 29' feet of 1/2" would I have the same pressure as above in "B"?
Thanks... :)
