DOUBT Related to calculation

Hi everyone,
I'm working on a problem statement as mentioned in the attachment. The Re=200 for the inlet.
I have kinematic viscosity but didn't got any x(length)
Should I assume x=1 and calculate inlet velocity.
And should I use bulk velocity (i.e. 2/3 of v_max) to calculate Re at upstream an step

The Re number is defined using the step height S. Thus, you have all needed. The velocity is uniform at the inlet.
