Are you one of the authors of Fluid Mechanics textbook by Cengel and Cimbala, Edition 4 ?
Yes, indeed.
at around minute 10:35 you verify that the Laplacian of the potential function is zero, but incompressibility was already given in the question...So I assume this check is simply to identify calculations errors?
Yes, just to verify that we did not make any algebra mistakes. It is always wise to double-check your results.
By the way, I would appreciate if you would tell your friends about the free resources on my TH-cam channel.
Thanks for the reply!@@johncimbala
