When designing a fluid power system, it is important to separate the concepts of flow and pressure. The pressure determines the force available, and the speed of the actuator determines flow. There is no argument there. But we need to understand that we cannot completely separate flow and pressure. Let me explain: What causes flow […]
I have a collection of equations floating around in my head for use when trying to come up with a fluid power solution. The problem is, many times what I am trying to find is embedded in the equation. For example, I can rattle off the power equation using torque and rpm: P = T […]
By Dan Helgerson, Fluid Power Journal Technical Editor I have an opinion about using bar vs MPa. I have had the privilege of working on the equations for the International Fluid Power Society certification study guides. I was directed to do so using ISO standards where they applied. As a result, I had to learn […]
By Dan Helgerson, Fluid Power Journal Technical Editor Merriam-Webster defines meme as a noun meaning “an idea, behavior, style, or usage that spreads from person to person within a culture.” It was originally coined by Richard Dawkins in 1976 in his errant attempt to explain everything within a framework of evolutionary processes, including changes in […]
