Webdynamic viscosity. In engines, the density of the lubricant continu-ously changes due to changes in particle content and temperature. Hence, dynamic viscosity is the true indicator of oil quality. There are very few systems such as the rotating cylinder viscometer that can measure dynamic viscosity [2]. These instruments are large WebA box with the weight of 15 N is sliding over an inclined surface. There is a layer of engine oil (dynamic viscosity 0.012 kg/m.s) between the block and the surface. The width of the block normal to the page is 20 cm. Determine the thickness of the oil so that the box slides down with a constant velocity of 5 m/s. [4 marks] 50 cm 30 cm V = 5.0 ...
