Write VBA programs to solve problem 7.18 using the Newton- Raphson method and the secant rule. Use five different initial values for solving the problems and report your results. 7.18. The Colebrook formula (Colebrook, 1939) can be used to determine the friction factor f, for turbulent flow through a rough pipe as a function of the Reynolds number, Re, and the relative roughness, ?/D, where ? is the equivalent roughness and D is the pipe diameter. lD 2.5 20log 37 Rev If Re = 500,000 and ?/D = 0.004, determine . Assume fo = 0 020 as a starting value. Write VBA programs to solve problem 7.18 using the Newton- Raphson method and the secant rule.
