1. The Darcy friction factor is used to calculate flow loss through pipes. The Reynolds number is
also a unitless quantity used in fluid flow computations. Write a MATLAB function M-file
named DarcyFricFact to compute the Darcy friction factor using the formula shown below. The
input arguements are pipe roughness, pipe diameter, and Reynolds number. The output argument
is the friction factor. It is not possible to determine the friction factor explicitly—there are many
approximations. You must use the Goudar equation to compute the friction factor, f.

. The function should halt and return a red error message if the following conditions are not met:
• Scalar input for pipe roughness and pipe diameter • Pipe roughness and pipe diameter
must be positive numbers. • (optional) Reynolds number must be greater than 4000. The
function must be vectorized to allow array input for Reynolds number & corresponding array
output for the friction factor
