This lecture series was recorded live at Cal Poly Pomona during Fall 2014. The textbook is Munson et al., "Fundamentals of Fluid Mechanics (7th edition)."

Man, imagine having a professor that could actually teach. Unfortunately, I don't.

This man is a Godsend.

[samslater]

If only I had a John Biddle... In short, friend ahead. Actually explaining how to approach a problem? This man is a blessing upon my grade and

[mehmetcanucar]

This helped me a lot on my midterm exam. Thanks!

I do not remember the equations used to solve problems 3.6 and 3.12. Which lecture were those derived in?

[SeekTheTruthAndTruth]

Sir, have you taught the equations that are required to solve first two examples in this video.i couldn't find them in lectures.

[edwintan]

@42:40, when you use the second bernoulli's equation to solve for P3 (Pstag), would the left hand side be equal to 0(because you corrected the P1 and v1 to equaling zero by placing point 1 outside of the vent). Would there then be two answers for P3?

[A.Hisham]

Well, z1 can be found using the manometer equation. 48:34

1hr 7mins into this video(the bathtub example) sums up this video beautifully lol

[justaman]

also why is this a non steady flow? is that because of the number of outlets? or is it just stated in the problem?

[eduardoduran]

58:10 why is the dB/dt = 0? isnt it unsteady flow?

[lecturesfromleeds]

Do mini windtunnels for classrooms exist? 🤔 If not I bet they would be pretty easy to build, using clear, see through plastic

[TheMetallicbrains]

i guess it's problem 3.46 (not 3.48) in textbook (p.145), that prof. Biddle solves at 25:15.. am i wrong ?

[kingdemon]

Did sir cover chap 6 differential analysis of fluid flow?

[hothanhdanh]

41:51 still don't get it why the P3 is zero if we calculate from equation point 1 to point 3. Seems like Prf. Biddle had a problem at that then he moved to the equation from point 2 to point 3. Can someone explain to me please ?

[mrzombiesbo]

For problem 3.36 in this video, is point 2 considered to be at atmospheric pressure?

[yogeshcgowda]

@1:01:15, even though its not steady state why do we take LHS = 0, even in main continuity equation @51.15 why is LHS (time.rate change of B(mass) of sys ) = 0 even before assuming its a steady state . PLEASE, IF ANY KNOWS ANSWER IT.

[syakirazmi]

At 48:43 . If I use bernoulli's point 1(water surface) to point 3 (Top of fountain) . The γ for the Pa pressure is γ of AIR, right?

[SsSs-tobb]

Sir, what if the area at point 2 from the last question is not triangle, but let say, its a parabola, shall we approach it in the same way as triangle?

[chrisfranklin]

Im confused as to why he sets R=6-n for the force in the n direction Euler equation. Surely from the diagram we can see R is 5?

[fakhreali]

in the wind tunnel problem. what is the value of gamma oil ? also, the answer h?
