Reynolds Number Calculation The Reynolds number (Re) of a flowing fluid is calculated by multiplying the fluid velocity by the internal pipe diameter (to obtain the inertia force of the fluid) and then dividing the result by the kinematic viscosity (viscous force per unit length). Kinematic visc...
to a publication of the American Petroleum Institute (API 13D), the annularflow Reynolds numbershould be calculated by substituting the difference between the hole diameter and thepipe diameter(i.e., the so-called hydraulic diameter) for the diameter of the pipe in the classic calculation.15 ...
(parabolic). Between 2,000 and 4,000 the flow is in the transition region. At 4,000 and above the flow is in the turbulent flow area and the profiles are fairly flat. Thus, calculation of the Reynolds number will define the flow velocitypattern and approximate limits of the meter’s ...
Since the model assumes an axisymmetric incompressible high Reynolds number flow, it is only applicable to the calculation of aerodynamic characteristics at zero angle of attack. The flow is assumed to separate from the canopy at its surface discontinuity, i.e. the canopy hemline. The vorticity ...
In this paper, several well-known low-Reynolds-number turbulence models, including MK, are critically reviewed against DNS data and RANS calculation results to find the reasons, if any exist, for the superiority of MK model. The most outstanding factor identified may be the fact that MK ...
This paper presents an analytical formula for the calculation of drag on an axially symmetric body moving steadily with a uniform speed in a microstretch fluid. The body is assumed to move axially in such a way that an axisymmetric flow around it is produced. The formula is constructed under...
For the calculation of the equivalent Reynolds number, the required friction factors are obtained as follows: flo=0.079×Relo−0.25=0.079×2271−0.25=0.01144 fvo=0.079×Revo−0.25=0.079×22114−0.25=0.006478 Constants required for the two-phase multiplier evaluation are calculated as follows: A1...
