helpdevelop a python programming for pressure drop calculations using reynolds number, flow rate and

roughness of pipe. The coding must include the following elements: A complete design in the form

of a flowchart. $1$ multi selection structure. $1$ nested repetition structure. $3$ user defined functions

with $1$ of it includes array manipulation for numerical calculations. All user defined functions must

be in individual files. $1$ built in function from library for numerical calculation.

$2$ array implementation with $1$ array manipulation. $2$ file operations$($ input and output$),1$ data

visualization graph.

Assume the values and use proper formula equations.
