Secant method pipe sizing excel

Please use the colebrook white eqn as the function to perform secant method on.

I’m trying to find the diameter of a pipe using the secant method

Values of x between 0.3 to 0.8

The flow = 0.77 ft^3/s

Kinematic viscosity of air = 1.62*10^-4

k= 0.49*10^-5

Pipe Length = 13 ft

g=32.2 ft/s^2

hf= 199.5

I need you to find the root and show your steps and answer the question of what the
diameter would be.
Please let me know if some required variables are missing because this is a project
and I had to make and calculate my own variables

THE WORK MUST BE DONE IN EXCEL
