MATLAB: Matlab unrecognized function or variable

unrecognized function or variable 'pvd'.

p=1.23;
D=.005;
V=40;
mu=1.7910^-5;
e=.0015;
Re=pVD/mu;%reynolds number equation
f=@(x)(1/sqrt(x)+2log(e/(3.7D)+2.51/(Resqrt(x))));
a=.008;
b=.08;
while abs(b-a)>1e-9
c=(a+b)/2;
if f(a)*f(c)<0
b=c;
else
a=c;
end
end
fprintf('Root found: %.10f\n',c)
fprintf('Function value at root %E\n',f(c))

Best Answer

Correct these two lines
Re=p*V*D/mu;%reynolds number equation
f=@(x)(1/sqrt(x)+2*log(e/(3.7*D)+2.51/(Re*sqrt(x))));
