A sliding contact bearing is operating under stable condition. The pressure developed in oil film is p when the journal
rotates at N rpm. The dynamic viscosity of lubricant is μ and effective coefficient of friction between bearing and journal
of diameter D is f. Which one of the following statements is correct for the bearing? [IES-2001]
(a) f is directly proportional to μ and p
(b) f is directly proportional to μ and N
(c) f is inversely proportional to p and f)
(d) f is directly proportional to μ and inversely proportional to N
