Hi,

 

You are nearly  there.  You use a solve block.  Solve blocks are available in MathCad 11/14/15 and Prime.

Enclosed is solution in Mathcad and PDF of Mathcad.

Another approach is to use the Swamee-Jain equation.  No iteration required.  It's accurate to around 1% of Colebrook, which is plenty close for most flow work.

Thanks. It seems an easier way to solve the equation.
