This question is one of the questions of the Fluid Mechanics I course. Please solve the a), b) and c). I would be very happy if you could solve the a), b) and c) step by step on real paper. Because I really want to understand this question. Thank you.

1. Considering 2-D, plane Navier-Stokes equation form as given (tV+VV)=p+2V a) Obtain non-dimensional form using the following reference variables: ReferencevelocityU,referencelengthL,referencepressure=U/L b) Simplify the equation you obtained in part (a) for creep flow (Creep flow means that viscous forces become extremely dominant when compared to the inertial forces.) c) Using the stream function u=y,v=x, show that 2w=0 is valid for the equation you obtained in part (b)
