my Lord - this is excellent lecture-- too long for me to under stand -- please make 3 short lectures - thank u my lord - amarjit - india- advocate delhi high court
I try to keep my lessons under 15 minutes, which seems to be a good compromise between too short and too long for a single topic. By the way, I have two-minute videos about several topics including fluid mechanics, math, science, and the Bible. You may enjoy those better if you like short videos. Thank you for your comment.

Yes, we are assuming one-D flow because at such high speeds the boundary layers are tiny compared to duct diameter. In these approximations we also neglect friction. Note that these flows are more like wind tunnels with nearly uniform flow rather than like long fully developed pipe flows which have highly non-uniform velocity profiles.

I put a line through my V (like a strikeout) to indicate volume. I use a normal V to indicate speed (magnitude of velocity). When typed equations and in my book, we use an arial font for volume and Times Roman Italic for speed to distinguish them. Thank you for your comment.

hi professor, i would like you to check for my workings .. i've been trying on doing some past exam papers, but i don't know whether what i do is right or wrong 🥺🥺may I pay you for tutor service :(
Thanks, it was perfect for me. I did return to compressible flows after 3 years and forgot all theese relations. Nice summary
Excellent video!

Are you assuming the flow in the duct is uniform? In a real duct, I would expect a nonuniform flow since the velocity at the duct boundary is zero.
How realistic is this assumption if analyzing flow through a real duct?
Yes, we are assuming one-D flow because at such high speeds the boundary layers are tiny compared to duct diameter. In these approximations we also neglect friction.

@@johncimbalaThank you for replying sir! Good job on your fluids videos!
Is V velocity or volume?
I put a line through my V (like a strikeout) to indicate volume. I use a normal V to indicate speed (magnitude of velocity). When typed equations and in my book, we use an arial font for volume and Times Roman Italic for speed to distinguish them.

I do not have time to do that. You will need to find someone else. sorry.
