Afluid flows upward through a vertical cylindrical of length (l) and radius (r). assume that the flow is laminar and fully developed. (a) list and describe the boundary conditions. (b) apply the continuity equation to fully developed laminar flow of an incompressible liquid in a cylinder. explain each simplification. (c) apply the continuity equation to flow of an incompressible liquid at the entrance to the cylinder- before the flow becomes fully developed. explain. (d) given the volume flow rate desired in the annulus (q), describe in detail how you would determine the required pressure difference from the entrance to exit of a straight vertical cylonder of a height (l) and radius (r). define any symbols you use not already defined.
