Extracted text: 1) A cylindrical capsule filled by liquid with SG = 1.5 is falling inside a pipe, as depicted in the figure. The small space between the capsule and the pipe is lubricated with an oil film that has viscosity (u =0.1 x 10-3Pa.s).. Find the steady Pipe Oil film rate of descent of a capsule with diameter d = 50 mm, and length I = 100 mm sliding inside a vertical smooth pipe that has inside diameter D = 52 mm. Assume that the capsule is concentric with the pipe as it falls. Capsule
