OP warned about not using the template
water moves over a stationary horizontal flat plate of one-meter length. if velocity of water is 1 m/s, draw boundary layer and friction coefficient versus x for this plate.

hint: start your curves from x=1cm.


Professor asked us to do it in Matlab or Excel and I'm not sure I understand how to do it.

Hi, Sam!

There are expressions for boundary layer thickness and friction factor as functions of x (the friction factor is a function of Re, which in turn is a function of x) for flow over flat plates. Are you aware of them?

If I understood correctly, your professor is asking you to graph the boundary layer thickness and friction factor from x = 0.01 m to x = 1 m using said expressions. IMO, it's just easier to do this in Excel.
