In boundary lubrication, the coefficient of friction ranges about ______(a) 0.05-0.1(b) 0.5-0.15(c) 0.05-0.15(d) 1-1.5This question was addressed to me by my college director while I was bunking the class.I'm obligated to ask this question of Mechanism of Lubrication topic in section Lubricants of Applied Chemistry

Answer» CORRECT answer is (c) 0.05-0.15

Easy EXPLANATION: In boundary lubrication, the thickness of the FLUID film MUST be 1000^oA. The coefficient of friction is about 0.05 to 0.15. This THIN film contains the one or two layers. Thus it is called as thin lubrication or boundary lubrication.
