Plug flow is obtained when the fluid velocity is constant across a plane normal to the flow direction. Plug flow is an ideal case and could only be exactly obtained in the lab with, e.g., a piston and cylinder. Plug flow can be approached in the following cases: •turbulent flow in a pipe •laminar or turbulent flow in a packed bed of solid .
