I have a practical question about a garden irrigation system I'm thinking about creating. Instead of connecting this "drip system" to my faucet which only has expensive water from the government, I'd like to connect it to a water barrel that collects rain water.
I have the current setup in mind (apologies for my programmer art):
A hose is running through my 4 garden beds (only two drawn). I figure the total hose length would be about 15 meters, with a diameter of I guess 1 cm (typical garden hose). I would then make holes in the hose, and connect smaller tubes. I got this idea from http://www.prettyprudent.com/2011/03/prudent-home/irrigation-system-for-raised-bed-garden-2/
The question I have would be: is the system of "communicating barrels" enough to ensure the water from the barrel reaches all the way to the end of the hose? Or would I need a pump to ensure pressure? Is there a way to calculate these things?
Thanks in advance (I haven't bought anything yet)!
