Plug flow reactor model — The plug flow reactor (PFR) model is used to describe chemical reactions in continuous, flowing systems. The PFR model is used to predict the behaviour of chemical reactors, so that key reactor variables, such as the dimensions of the reactor,… … Wikipedia
Plug valve — Plug valves [American Petroleum Institute Standards: API 6D Pipeline Valves ; API STD 599 Metal Plug Valves ] are valves with cylindrical or conically tapered plugs which can be rotated inside the valve body to control flow through the valve. The … Wikipedia
Plug flow — In fluid mechanics, Plug Flow is a simple model of the velocity profile of a fluid flowing in a pipe. In plug flow, the velocity of the fluid is assumed to be constant across any cross section of the pipe perpendicular to the axis of the pipe.… … Wikipedia
