Kinematic viscosity ( ) is an important physical property of fatty acid methyl esters ( FAME ) and biodiesel. In this work, the Martin's rule of free energy additivity is extended to cover the kinematic viscosity of saturated and unsaturated FAME commonly found in nature. The proposed model ...
Kinematic Viscosity = v = u/p = (kg/(m x s) x 10-3) / (kg/m3) = m2/s x 10-6 The cgs physical unit for kinematic viscosity is thestokes(St), named after George Gabriel Stokes. It is sometimes expressed in terms ofcentistokes(cSt). In U.S. usage,stokeis sometimes used as...
The default values used are for turbulent air flow in a 315 mm duct with 6 m/s (0.47 m3/s). The kinematic viscosity used to calculate the Reynolds Number is 15×10-6m2/s . hydraulic diameter - dh - (m, ft) roughness of surface - k - (m, ft) Reynolds Number - Re Load ...
Property data for potassium hydroxide (KOH) and sodium hydroxide (NaOH) - water solutions have been added to theBrines property group. The properties include density, specific heat, viscosity, thermal conductivity, enthalpy, normal boiling point, saturation%, freezing point, and vapor pressure as fu...
The ZeroEquation turbulence model provides the effective viscosity (ν+νt) to the Navier-Stokes equations. The kinematic viscosity of the fluid calculated based on the Reynolds number is given as an input to the ZeroEquation class. The Zero Equation turbulence model is defined in the equation...

Thekinematic viscosityof the water at 290°C is equal to0.12 x 10-6m2/s. The primary piping flow velocity may be about17 m/s. The primary piping of one loop is about20m long. TheReynolds numberinside the primary piping is equal to: ReD= 17 [m/s] x 0.7 [m] / 0.12×10-6[m2/...
Re is the Reynolds number, Re=Ul/v where U is the reference velocity, l is the characteristic length and v is the kinematic viscosity of the fluid. Velocity vector, pressure and time are denoted with u, p and t, respectively. The proper boundary and initial conditions are imposed on ...
The Reynolds number for a pipe or duct can also be expressed in Imperial units Re = (7745.8) u d / ν where Re = Reynolds Number (non dimensional) u = Velocity (ft/s) d = Pipe diameter (in) ν =Kinematic Viscosity(cSt) (1 cSt = 10-6m2/s )...
