Acknowledgements. Introduction. Most mechanical devices such as fans, pumps, etc. produce vibration.. Vibration is easily transmitted through solid materials and may ‘appear’ elsewhere producing troublesome vibration and/or noise.. Viscosity is how engineers measure the resistance of fluids when being . deformed:. τ. = . μ. (du/dy. ). The less viscous the fluid, the greater its ease of . movement.. Viscosity is useful for calculating the force needed to move a fluid. For example, in these industries: . (Supplemental to . LHO aLOG 6392. ). J. Kissel. G1300561-v1. 1.
