Subject: Help with while loop
Please help with trying to make the while loop work

e =0.0015;

D =50;

V =2;

Dm =0.05;

v =1.01*10^-6;

Re = V*Dm/v;

N =1000;

f = linspace(0.008,0.1,N);

i = 0;

f_abs = 1;

FF = 0.008;

while FF(end) < f_abs;

i = i + 1;

FF = log(e/D/3.7 + 2.51*Re*sqrt (f(i)))*sqrt(f(i))*-2;

end

My aim is to iterate through f until the equation or FF is equal to 1 or less than .001 away from 1.

Please note i am a beginner user and have no prior programming knowledge

Thanks Jimmy
