Default Connecting 3-4 sprinklers to one faucet

I am planning to connect 3-4 sprinklers to one faucet via a 4-way
adapter and have one technical question/doubt: The hose connecting the
adapter to the faucet would carry 3-4 times more water than individual
hoses connecting it to sprinklers. What capacity should these hoses be?


Naively, I was thinking 3/4" hose to faucet and 5/8" hoses to
sprinklers. Or would another combination make more sense?

Thanks.


The rate of flow, thus the sprinkler coverage depends on the ID of the hose
(carrying capacity), and the pressure "seen" at the sprinkler. In this
case, the limiter is not the hose carrying to the adapter, rather, the
faucet outlet itself. A typical faucet cannot deliver enough water for
appreciable coverage for 4 sprinklers. The reason being is that total water
coverage is limited by the faucet's ability to deliver:
1. Sufficient pressure
2. Sufficient water volume
The amount of water delivered by the faucet also affects pressure. The more
volume, the less pressure, and, vice-versa given the amount of flow alloted
by opening the faucet.

For maximum flow, use the largest available hose. Doesn't matter regarding
feed hose to adapter or the other 4 hoses. Reason being is the faucet
(source of water) can't keep up with sufficient pressure to allow sufficient
sprinkler coverage. At the same time, using 5/8" hose to adapter, and 1/2"
hose to sprinkler may keep some sprinklers alive (moving) providing
sufficient pressure.
