My first WEFTEC
This week I had my first WEFTEC experience. I live in LA and WEFTEC was held at the LA Convention Center, so I drove on over to see the exhibits....

Hypermiling
With fuel prices creeping up again I thought it appropriate to share some of my experiences with hypermiling. “Hypermiling” is a method of increasing your car’s gas mileage by making...

Specific Speed – Does it Matter?
To the pump engineer or pump manufacturer specific speed is terrifically important. To the specifying engineer or user – maybe, maybe not. The term specific speed comes up frequently in...

Is there any confusion about NPSH?
Net Positive Suction Head (NPSH) is perhaps the most misunderstood concept in pumping technology. The main source of confusion stems from multiple uses of the term in different but related...
