Question 43
Open questionXE-BNAT2 marksNeeds review
The horizontal belt of negligible weight shown in the figure moves with a steady velocity (
) of 2.5 m/s and skims over the top surface of an oil-film of depth
= 3 cm. The length (
) and width (
) of the belt are, respectively, 2 m and 60 cm. Find the viscosity of the oil (in Pa-s), given that the minimum power required to move the belt is 100 W. Neglect the end effects. (Round off to two decimal places)
