Due: Friday, April 15, 2022 Problem 1: two long concentric Consider and R, (see figure cylinder of radius rotating The inner cylinders of radii 1 R and R and cylinder of radius 1 R is rotating below). R is rotating at For this problem, can be neglected 27 water. Since L>> R and R, end effects axial directions). 1 (a) What is the velocity (b) What is the pressure the fluid bet (i.e., you between the rotating cylinders variation variation between the rotating cylinders is the torque exerted on (c) If co=0 and (RR/R, < < < 1, what 1 2 1 Problem 2: W R Rz r?
