A steel cylinder falls through a vertical pipe due to the influence of gravity. The inside surface of the pipe is coated with an oil film. The pipe inner diameter (D) is 100.5 mm. D- Pipe The cylinder has a diameter (d) of 100 mm, a length (L) of 200mm, and a mass of 12.6 kg. Oil film The lubricant is SAE 20W oil at 10°C, which L has a viscosity of 0.3 N-s/m2. Cylinder Determine the velocity of descent of the cylinder through the pipe. A steel cylinder falls through a vertical pipe due to the influence of gravity.
