A viscous liquid (u= 0.017 lbs/ft², p = 1.81 slugs/ft') flows through the annular space between two horizontal, fixed, concentric cylinders. (a) If the radius of the inner cylinder is ri =1.6 in. and the radius of the outer cylinder is ro = 2.8 in., what is average velocity when the pressure drop along the axis of annulus is 80 lb/ft² per ft? (b) If the inner cylinder does not exist, what is the average velocity given the same pressure drop.
