Fluid In Motion
Studying hydraulics for proper pool operation

By Connie Sue Centrella

The importance of hydraulics in swimming pool/spa design and application has been misunderstood by some aquatic professionals who believe that understanding hydraulics is only necessary when first designing an aquatics facility. Hydraulics plays an important role in the everyday operation of aquatic facilities. Knowing how the pool circulation system operates on a daily basis can curb excessive and sometimes unnecessary repair costs. The aquatic manager should have the ability to recognize changes in flow rate, analyze fluctuations in pressure and vacuum gauge readings, and be capable of making minor adjustments to the system to enhance the circulation and filtration process.

Early Pioneers Of Hydraulics
Hydraulics was first studied by Archimedes (287-212 B.C.).  The Greek mathematician, physicist and engineer invented the first pump, called a screw pump.  The Archimedes screw was operated by hand and raised water efficiently.
