What is the resistance to flow in the range of bar offered by a new filter element?(a) 0-0.1(b) 0.1-0.3(c) 0.3-0.5(d) 0.5-0.7The question was posed to me by my college director while I was bunking the class.Asked question is from Lubrication and Lubricants topic in section Lubrication and Lubricants of Automotive Engine Design

Answer» RIGHT choice is (C) 0.3-0.5

The best I can explain: The RESISTANCE to flow offered by a new filter element is about 0.3-0.5 BAR. However, with the use, the resistance increases due to clogging of the filter element as the time passes by due to ACCUMULATION of dirt and other impurities.
