equivalent hydraulic diameter.

n: the flow pattern is classified three kinds：laminar flow，turbulent flow and excessive flow according to hydraulics principle

n: that branch of engineering which treats of liquids in motion, or its action. It is the know-how about the effects of fluid velocities and pressures and the power involved. The pressure of either a standing or amoving column of fluid is directly related to

a general term referring to how fluids move and unloads cuttings, etc. in a well. Most common in drilling to insure claring and effective pressure control.
