Colebrook-White Equation软件

Computes the friction factor in pipes for given values of the Reynolds number (Re) and the relative roughness coefficient (epsilon).

软件应用简介

Syntax: 

f = colebrook(Re,epsilon)

Example 1: Single Re, single epsilon 

Re = 1e5; 

epsilon = 1e-4; 

f = colebrook(Re,epsilon)

Example 2: Multiple Re, single epsilon 

Re = 5000:1000:100000; 

epsilon = 1e-4; 

f = colebrook(Re,epsilon); 

plot(Re,f)

Example 3: Single Re, multiple epsilon 

Re = 1e5; 

epsilon = linspace(1e-4,1e-1,100); 

f = colebrook(Re,epsilon); 

plot(epsilon,f)

Example 4: Multiple Re, multiple epsilon 

Re = logspace(4,8,100); 

epsilon = linspace(1e-4,1e-1,100); 

[RE,EPSILON] = meshgrid(Re,epsilon); 

F = colebrook(RE,EPSILON); 

surf(RE,EPSILON,F)
