and D are the unknowns
c3
c3 is known
where
c4 is known
Solution Procedure:
(i) Assume a value for f
(ii) Calculate D from
(iii) Calculate
(iv) Calculate Re from
(v) Using and Re, determine f
(vi) Compare f obtained in (v) with f assumed in (i). If the two values are approximately the same, STOP. If not, repeat steps (ii) through (v) until convergence is attained
