Urgent! Expert in fluid mechanics needed.
A journal bearing consists of a shaft whose diameter is 0.08 m in a sleeve with a diameter of 0.0803 m. The sleeve is 0.1 m long. The clearance space, which is assumed to be uniform, is filled with SAE 30 Western lubricating oil with a viscosity of 0.11 Pa.s. If the shaft is rotating at a rate of 120 rpm (revolutions per minute), then determine:
a) The velocity profile (15 Points)
b) The shear stress distribution (10 Points)
= 120 rpm
L = 0.1 m
D = 0.08 m
