Question

Air Under standard conditions flows through a 4.0.mm diameter down tubing with an average velocity of V=50 m/s. For such conditions the flow would normally be turbulent. However, if precautions are taken to eliminate disturbance to the flow (the entrance to the tube is very smooth, the air is dust free, the tube does not vibrate, etc) it may be possible to maintain laminar flow.

Find

(a). Determine the pressure drop in 0.1.m section of the tube if the flow is laminar.

(b). Repeat the calculations if the flow is turbulent.

(c) Use MATLAB or other tools to solve the Colebrook Equation, compare result with the Haaland equation and Moody Chart, which should be same (or a close) number.

(d) Copy your program (for solving Colebrook Equation) from MATLAB (or iteration data from Excel).

I just need Part (c) and (d)
