Question

A viscous liquid (μ = 0.012 lb·s/ft2, ρ = 1.79 slugs/ft3) flows through the annular space between two horizontal, fixed, concentric cylinders. If the radius of the inner cylinder is 2.5 in. and the radius of the outer cylinder is 3.5 in., what is the pressure drop along the axis of the annulus per foot when the volume flowrate is 0.16 ft3/s? Δp/l = Enter your answer in accordance to the question statement lb/ft2 per ft
