It’s all about the curve

Do you know the curve?

One of the toughest things for most major league hitters is to identify a curve.  More hitters are able to hit a fastball with regularity than they are a curve ball.  Curves can be an item of mystery.

In the irrigation industry we too are faced with curves.  All irrigation systems have an operational curve that to a great extent determines the operational efficiency of the system.  In recent years, relative to the age of our industry, manufactures have made many improvements in products that help us smooth out the operational curve of the systems we install.

The following are a few examples:

  • Pressure Regulating Valves
  • Pressure Regulating Sprays
  • Pressure Regulating Rotors
  • Pressure Regulating Bubbles & Emitters

See a trend here?   Yes, pressure regulation is the key to getting your installed system to operate within the manufacture’s product design curve.  All water emission devices have an optimum operating point for maximum efficiency. (The sweet spot of their design curve.)

How to design for the curve

If we are installing a system that has a water source that delivers water within a predetermine range of pressures such as city water, we can design our system based upon known factors.  If the water supply has a high static pressure probability then pressure regulation equipment will be necessary for maximum system efficiency.

If we are designing a system the will be using a water source from a lake, pond or stream we will need to be considering another type of curve, the pump curve.   All pumps have a curve that predicts the number of gallons of water per minute that can be delivered at a given pressure.  This information along with the information of your system curve will help you determine the correct pump to pair with the system you have designed.

Hitting a Home Run …

If you have an understanding of these basic principles prior to installing that first piece of pipe or prior to digging that first hole, you will be well on your way to hitting your “curves” with the sweet spot of your performance bat.  A great season is built around understanding and applying your knowledge.  If you have any concerns or questions, your distributor team is here to support you.
