ABSTRACT
EXAMPLE: LIQUID INERTANCE For a typical hydraulic oil (/l = 2 x 10-6 lbrsecjin2, p = 0.8 x 10-4 lbrsec2 lin4) flowing in a tube of radius R = 0.05 inch, the frequency w is about 500 radjsec, for example. Thus, well below 80Hz we use~ the physical mass, near 80Hz we use~, and well above 80Hz we use the physical mass itself.
