Question

Significance of alpha and beta in equation of viscosity

Answer 1

Answer:

Viscosity: It is the property of lubricant due to which it offers resistance to its own flow. Viscosity index: It is defined as rate of change of viscosity with respect to temperature. Significance: It is the most important property which determines the performance of lubricating oils under operating conditions.

Answer 2

Answer:

Explanation:

Significant variation of free volume would not be envisioned as there are no added ... To predict the pressure-viscosity coefficient of oil-refrigerant mixtures, the α value ... The equation used is quite insensitive for errors in αrefr at the relevant .... p, and β is the temperature–viscosity coefficient, also in units that match that of ...
