PROGRAM TO SOLVE
(OP)
Dear all,
I am having difficulty in solving this problem in c++.
1/sqrt(f)=2*log10(Re*sqrt(f))/2.51
It is required to calculate f. Re is given as 128592.72.
Thanks.

RE: PROGRAM TO SOLVE
0= 2*log10(Re*sqr(F))-2.51/sqr(F) ; Replace 0 with Y.
Select an arbitrary value for F and calculate Y
Change it with dF and recalculate. Put a straight line
across these two points - solve its zero xing.
Replace this into F and repeat until Y=0
