When the lubrication is arranged so that rubbing surfaces are separated by a fluid film, and the load on the surfaces is carried entirely by the hydrostatic or hydrodynamic pressure in the film, it is known as
In hydrodynamic friction, the friction force does not depends on the lubricant viscosity.
______________ is the friction, experienced between the rubbing surfaces, when the surfaces have a very thin layer of lubricant.
_____________ is the friction, experienced between the rubbing surfaces, when the surfaces have a thick layer of the lubricant.
A multiple disc clutch has five plates having four pairs of active friction surfaces. If the intensity of pressure is not to exceed 0.127 N/mm2, find the power transmitted at 500 r.p.m. The outer and inner radii of friction surfaces are 125 mm and 75 mm respectively. Assume uniform wear and take coefficient of friction = 0.3.

A sliding bearing in which although lubricant is present, the working surfaces __________ contact each other at least part of the time, is called boundary lubricated bearing.
The bearing friction includes the friction due to the main bearing connecting rod bearing and other bearings.
If p = bearing pressure on projected bearing area, Z = absolute viscosity of lubricant and N = speed of journal, then the bearing characteristic number is given by
