In fluid dynamics, the entrance length is the distance a flow travels after entering a pipe before the flow becomes fully developed. Entrance length refers...

and topical guide to fluid dynamics: In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes...

In fluid dynamics, head is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From...

In non ideal fluid dynamics, the Hagen–Poiseuille equation, also known as the Hagen–Poiseuille law, Poiseuille law or Poiseuille equation, is a physical...

In fluid dynamics, the Graetz number (Gz) is a dimensionless number that characterizes laminar flow in a conduit. The number is defined as: G z = D H L...

In fluid dynamics, the process of a laminar flow becoming turbulent is known as laminar–turbulent transition. The main parameter characterizing transition...

In fluid dynamics, a gravity current or density current is a primarily horizontal flow in a gravitational field that is driven by a density difference...
