Water pressure, flow, and pipe size - 1

Irrigation demonstration at Miami Dade College Kendall Campus shows that smaller pipe size diameter causes reduced water pressure. This can reduce irrigation sprinkler head coverage, reduce irrigation uniformity, and reduce efficiency.

The problem with this video is it might make people think that bigger pipe = more pressure. That's not really the case, and you do address that a bit. Bigger pipe just results in less loss of pressure. Most sprinklers will operate well on a wide range of pressures you would normally find at a home, from 30-80psi. Many can be adjusted manually. People have the misconception that if you go from a large pipe, say 4", down to a 1/2" sprinkler, you'll blow it up, because the pressure will be too high. That's not the case. As you said, you can only reduce pressure.

Finally a helpful video. I think I will stick with the 1 inch system I bought. Thank you!

Thank you!
This is a good practical demonstration of what we are doing in class.

Did my irrigation system following his advise of pipe size and was able to pull 27 sprinklers with 1.5 horse power shallow well pump. Just need to measure my the preasure at the end of the line to check the PSI. My neighbor has a bigger pump about the same amount of sprinklers and he has to run it in three zone because the person who did his sprinklers used 3/4 all the way.

How much pressure is on the supply line before turning on the sprinklers?

This was actually very good and eye opening. Thanks Doc.

You are Super Cool and loads of help.

I've been scouring UA-cam for helpful videos on how to assess a private well accurately / properly to determine how to design your irrigation system. Does anyone have suggestions or videos that explain the 101 of designing a system off a private well??

[@amish1000]

Wow ...Thank you very much ....was very well explained and helpful as well.

[@riversidedjs]

Great video, informative

[@luissonoma6255]

I have an inquiry, not irrigation related but maybe someone might know. I’m trying to run water to two rooms that will service a washer and two sinks. I’m tapping off a 1/2 pvc that feeds a hose in the backyard. Will connecting from it to a 3/4 pipe make it more pressurized or allow or allow it to have better water flow or is it already restricted since it’s from a 1/2 pipe? It will only run about 25’ to the rooms.

werry helpfull Professor. thanks.

[@feltingme]

So if I want to reduce the waterpik flosser pressure, do I simply need to reduce the opening of the end?

[@OU8Aspark]

What is the book called where we can look up this information?

[@amritpalsidhu6454]

You solved it , and very easy to understand thank you , i was searching some simulation app , if you know any that can be understandable like you explained .

[@arrheniusmagumane9066]

thank you for the explanation sir

[@navinsabban6521]

what is the relation between pressure and flow?

[@dgr5421]

Very helpful 👍

[@stevenreeves4766]

do you have the tables you refer to?

[@4STEVEJOY34]

At 2:21 What table? A link would be nice. I don't have the book.

[@rmoreland3583]

Nice informative video. He looks like Donald trump though

[@saeed6811]

Bhushan Shirwalkar it’s him in trump tower back yard

[@TheNYgolfer]

Really? He isn't fat, has a hell of a lot more hair with no bad die job or comb over and is a hell of a lot smarter.

[@GB-rb1up]

He is making irrigation great again. lol
