Calculating the Reynolds Number 2

Description

Calculating the Reynolds Number 2

Usage

Re2(D, V, nu)

Arguments

D	numeric vector that contains the hydraulic diameters "(four times the area in flow divided by the wetted surface) is a characteristic length" (m or ft) Reference: Lindeburg Manual
V	numeric vector that contains the average fluid velocity (m/s or ft/s) Reference: Lindeburg Manual
nu	numeric vector that contains the kinematic viscosity of the fluid (m^2/s or lbf-sec/ft^2) Reference: Lindeburg Manual

Value

the Reynolds number as a numeric vector for Re2

Examples

# from Lindeburg Reference page 17-8
# where
# D = 0.3355 ft
# V = 7.56 ft/sec
# nu = 1.41 * 10 ^ -5 ft^2 / sec
# and
# Re = 1.8 * 10 ^ 5

library(iemisc)

Re2(D = 0.3355, V = 7.56, nu = 1.41 * 10 ^ -5)

# compare to Re1(D = 0.3355, V = 7.56, rho = 1.937, mu = 2.09 * 10 ^ -5, units = "slug")

Re2(D = 0.3355, V = 7.56, nu = 1.08 * 10 ^ -5)
