WebbThe method employs the principles of vibration and measures the viscous damping due to the motion of a liquid placed in a cylindrical tube. The apparatus and the test liquid are treated as a dynamic system and the measured mechanical impedances are used to calculate energy dissipation due to the viscous damping.

Webb1 juli 2015 · The disc rotation around its own axis should be such that the torque acting on the disc due to disc/rock interaction is equal to zero (the disc is free to rotate). Although the disc rotation is crucial for the calculation of the disc/rock interaction force (see Section 2.2) , it does not affect the disc/rock contact length as well as the geometry of the rock … WebbFollowing is terminal velocity formula: v = 2 9 r 2 ( ρ − σ) η.
