91Nominal Pipe Size — (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures.[1] Pipe size is specified with two non dimensional numbers: a nominal pipe size (NPS) for diameter based on inches, and a schedule (Sched.… …
92Kármán-Howarth equation — In isotropic turbulence the Kármán Howarth equation, which is derived from the Navier Stokes equations, is used to describe the evolution of non dimensional longitudinal autocorrelation …
93Specific Speed — The net suction specific speed is a dimensionless number defined by centrifugal and axial pumps inherent physical characteristics and operating pointcite web| url = http://www.gouldspumps.com/cpf 0008.html| title = NPSH and Suction Specific Speed …
94Dean number — The Dean number is a dimensionless group in fluid mechanics, which occurs in the study of flow in curved pipes and channels. It is named after the British scientist W. R. Dean, who studied such flows in the 1920s (Dean, 1927, 1928). Definition… …
95Moody chart — The Moody chart or Moody diagram is a graph in non dimensional form that relates the Darcy friction factor, Reynolds number and relative roughness for fully developed flow in a circular pipe. It can be used for working out pressure drop or flow… …
96Rouse number — The Rouse number is a non dimensional number in fluid dynamics which determines how sediment will be transported in a flowing fluid. It is a ratio between the sediment fall velocity w s and the upwards velocity on the grain as a product of the… …
97Advance ratio — Diameter of the propeller. In aeronautics and marine hydrodynamics, the advance ratio at which a propeller is operating is the ratio between the distance the propeller moves forward through the fluid during one revolution, and the diameter of the …
