Insane Hydraulics
Bold and audacious blog about fluid power
Adequate sizing of hydraulic hoses is an essential step of any project. I am old-fashioned - I prefer good old nomograms and a ruler to calculators and specialized software - a harmless tribute to tradition, if you will, like using an analog pressure gauge over a digital one - simple and instantaneous.
In order to give this traditional method of sizing hydraulic hoses and pipes an internet-age twist, I came up with the following interactive page, which, hopefully, will find a place among your "engineering" bookmarks. You will need a JavaScript-enabled browser to view the nomogram correctly. Instructions: grab the circles to move the interactive line, enjoy. (The recommended maximum speed for suction lines is 1.2 m/s, return lines - 3 m/s, and pressure lines - 7.6 m/s).
