Colebrook-White Equation
MATLAB code to compute the friction factor in pipes for given values of the Reynolds number (Re) and the relative roughness coefficient (epsilon).
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)
