Recently, I wrote a blog about the use (or lack thereof) of algebra. I know you’re curious, so I’ll tell you: we STILL use it every day in the Application Engineering department at EXAIR. One thing we DON’T use every day, but got a chance to use this morning, was trigonometry. See, for our Atomizing Spray Nozzles, we publish the dimensions of the achievable spray patterns at certain distances, while using specific air & liquid pressures. Today, one of us got asked how far a particular nozzle would have to be to attain a smaller pattern than the minimum published. A few of us broke out our calculators, eager to test our math retention skills. I’ll spare you the math lesson, but, we were all able to visualize it as a right-triangle problem, solve for the angle (using the TAN-1 function of trig), apply it to the shorter opposite side, and, using the TAN function, solve for the new adjacent side. Only one of us forgot to check and see if his calculator was in “radians” mode. For all you non-math geeks, all the math geeks are enjoying a good laugh at Ryan’s expense right now.


Speaking of things you don’t use every day, I had the pleasure of discussing a material conveying application with a customer this morning. He needed to move a few hundred pounds of sand, but only once a month or so, and couldn’t justify the price of a standard auger-type mechanical conveyor system, and thought he was stuck with using a shovel and bucket. We discussed the application, and, based on some testing we’d performed in the Efficiency Lab, we figured he should be able to use a 2″ Heavy Duty Line Vac to convey 200-300 lbs in about a half hour, which sounded GREAT…and at a tiny fraction of the cost of the auger conveyor.

Whether it’s something you’ll use all the time, or once in a while…if it concerns compressed air, we’d love the opportunity to help.
