does using smaller pipes for your sprinkler system give you more water pressure.?

Answer 1

Using smaller pipes cause less flow and present some resistance to flow. If anything it will reduce the amount of water flowing in your sprinkler system and thereby will cover less area.

Remember pressure is only resistance to flow. You do not have pressure until you stop the flow.

Answer 2

Smaller piping means for a given flow rate more pressure drop per foot of piping length.

Using smaller piping will result in lower pressure at the point where you usually want the pressure to be higher which is the sprinkler heads.

Now if you have too much supply pressure and are trying to reduce the pressure at the sprinkler heads then the smaller piping will work in your favor.

Answer 3

From an Engineering student's point of view. I would say no. I didn't get much out of my Fluid Dynamics course, but one thing I remember is that water at the surface of a pipe doesn't move. Water near the surface of the pipe travels at a speed less than water at the center of the pipe. With a small pipe, water particles, regardless of where they may be along the cross sectional area of the pipe is close to the tube surface. Therefore water moves slow.
By getting smaller pipes, the only benefit is that you are saving water.
For a 'try this at home' experiment, get 2 straws. A drinking straw, and a bubble tea straw (one with wider diameter). In the bathroom over a bathtube, blow a mouthful of water as far as you can with one straw. Repeat with the second straw. Use your observations to arrive at a solution. Enjoy!

Answer 4

Technically, yes. Pressure = Force/Area.
So, the smaller the area (smaller diameter pipes) the higher the pressure in the pipe.
But, if the small pipes connect to a larger nosel, the increased pressure is lost. So, you probably really need smaller diameter nosels (sprinkler heads), but that will reduce your flow (gallons per minute).

Answer 5

Using smaller orifice on the sprinkler head will increase the water pressure and greater throw.

Answer 6

no...not usable water pressure and in fact, reduces usable water pressure considerably. The larger the pipe (within reason), the more nozzles you can use. ..stick with 3/4" pipe, you cannot go wrong. Good luck

Answer 7

Yes. Always with plumbing, smaller tubes = more pressure.
