Any Fluidics Engineers?

[micstrachan]

Hello,
Are there any fluidics engineers in the group? I’m thinking ahead to summer, and I have a feeling it’s going to be a hot one here in California. I have an idea I’d like to run by you.
For a little history, I have these great Arctic brand bucket top misters I use for the flock in the summer. However, the battery only lasts a couple hours. Plus, if they ran a lot longer, the bucket would run dry and eventually fry the pump.
I thought it might be nice to have a passive/gravity fed “drip” system, where I could fill a 5-gallon bucket (and cover it so nobody falls/jumps in and drowns) and have it slowly drip all day long. I could position it slightly higher than a little ditch they could dig in to keep cool. Could I just drill a couple tiny holes right in the bucket? If so, what size would be small enough to break the stream into drops? I’m thinking anything bigger (like a soaker hose?) might just run out of water super quickly. Thoughts?

Would one of these work for you??? I purchased this one, but use it for the children when they want to play outside in the backyard during HOT SUMMER. It does cool the immediate air as stated. Just attach to hose and mount overhead. I would stretch a rope between trees and attach this Misting hose to it. It has 6 nozzles, and according to their stated specifications, each nozzle sprays out as little as 1/2 GPH. that translates to 6 nozzles using up about 3 gallons per hour. That equals to an older toilet being flushed each hour. I know that the newer toilets flush with 1.5 gal of water. There are often times that they need to be flushed TWICE,,,, to send the goods down.
If water consumption is of HIGH CONCERN,,,,,, then it can be operated with less nozzles spraying. Just clamp off the hose so only 2 or 3 spray at a time..
WISHING YOU A cooool summer...................

The pressure of water in a gravity fed system is determined by the head of water (the height of the water above the end point of delivery) and the diameter of the pipe. Obviously as the head of water changes, so does the pressure. You may find a nipple that will work when your tank is full, but not say when it is a the halfway mark so the pressure you need to determine is the minimum, i,e, when the water in the tank is at it's lowest level. This will tell you what nipple bore will work when the tank is full, or at minimum.
The usual way to ensure that there is always sufficient pressure at the delivery nipple is to use a pump. Garden centers etc, sell such system for watering.
My house works on a gravity fed water system. I have 11 metres maximum which allows me to run an instant hot water heater in the winter, most of the time. If, however, the tank gets very low on water the pressure sensor that fires the pilot light won't work. So, for reliable performance I would suggest you fit a system with a low power pump. You're not after a power shower after all.

Just wanted to clarify one point. The system I posted is intended for hose pressure common to city water delivery, or other common sources found in the home. If you have a well pump, and are able to take showers, this will most likely work fine.
