This is the only explanation I have seen which does not skip over details of the way the resultant velocities arise. Bravo! Usually, it is impossible to tell if it is the inlet tip angle that is being talked about!
I have been searching video on velocity diagram from 5 years that could explained very easy. Now I finally find that one today. Make more such type of video. Sir Jey
Dear mandal dada, I am extremely impressed with your simple explanations of a 'big bang' looking theories. Late to notice your videos. Please continue posting. I am not only simply a subscriber of you, but a fan too!! Because I am a technical mentor, and i found a new way to teach the the novices in technical field.. kudos.. keep it up..
Understood sir..... The example of cart really made it easy & your video a class apart from others... Hope in other videos u will add such secondary items (like cart ) & would be glad if you can make videos in Bengali..
Exceptionally outstanding explanation. But still I have a doubt, sir, cart example.. you took is similar to buses which have exhaust pipe on left of the side of the bus. But when bus move forward or away from you(assuming you are on the back side of the bus, back side of bus facing you) the gases come towards you, and not away 10:08 , you have shown otherwise, where am I wrong, please explain.
sir plz clear the angle notation , as per axial compressor alpha is the angle b/w axial and absolute and bita is the angle b/w relative and axial but in case of centrifugal will it be same as axial or different?
Sir, i couldnot understand always about velocity triangle.please explain in detail.Firstly blade moves in ccw direction, we draw the blade velocity in the direction from right to left. Secondly air moves from me to towards front. We have to draw air velocity head to towards tail of blade velocity. And then we haveto draw relative velocity from tail velocity of air to blade velocity head. Kindly explain sir.
Respectably, I want to know that "Is velocity triangles and their equations are same for Pumps, Turbines & Compressors or they will be different in each case." Waiting for your reply. Thank You!
+Shah Rukh Jamil cant say same, but centrifugal pumps , compressors and axial pumps compressors have almost 'same look' velocity triangles. While for axial, centrifugal turbines have different..
It's explained well but only 1 error, V12= V1 - V2 where V12 is Velocity of 1 wrt 2... You are saying Cv+ U1 it should be Cv-U1=C... Other than this, it's excellent...
I have checked , and it seems all slides are correct in regards of the sign convention of vector and the concept of vector addition. however could you please tell me in which image you found difficult to understand with the same symbols as mentioned in it?
I was struggling with the velocity triangles, but now it's a piece of cake. Thanks a lot from Egypt ❤️❤️👌

Thank you! Now I understand velocity triangles at last! :D
i just went all the source to understand this.., NPTEL and all, You made my lif easier.

Best vedio I have ever seen for velocity triangle
Amazingly explained.....
Especially moving cart analogy...
Best video ever seen on velocity diagram...keep it up
Please make video on velocity diagram of axial compressor
Such a good and clear explanation in simple language, liked it ..Thanks :)
You clear my doubts on velocity triangle,thank you so much sir
Perfect way of explaining brother. Gr8 work.
Nice explanation sir, Thank you

really this is superb way to explain
thank you sir one of the best explanation i got
Jhakash jabardast jindabad....
Understood sir..... The example of cart really made it easy & your video a class apart from others...
Hope in other videos u will add such secondary items (like cart ) & would be glad if you can make videos in Bengali..
thanks a lot dear sir it solved a big head ache to me thanks from afg
Very well presented..
nice explanation sir, thank you.......very much
Thank you so much sir
Perfect explanation!
Thank u
.best explanation

+Nikhil the analogy is applicable when simobody is coming out of bus perpendicular to the direction of motion...could be stepping out of door.
Nice Explanation, if you could relate the angles at inlet and outlet (flow and blade), that would be cherry topping on cake.
Please make Vedios on remaining topics of compressors
Best explainatiin...!!!
Ca - U = Cr
Sir, I am sorry for pointing out that, but rest everything is nicely explained.
Good explanation sir
sir plz clear the angle notation ,
as per axial compressor alpha is the angle b/w axial and absolute and bita is the angle b/w relative and axial but in case of centrifugal will it be same as axial or different?
There is no as such standard notation. Follow the theory...
excellently exlpained !
Thanks a lot Sir.

Secondly air moves from me to towards front. We have to draw air velocity head to towards tail of blade velocity.

Precisely tell about your problem...
bro can u please do a lecture on centrifugal split casing pump working principle and parts and maintanance
Wah guru ji
Thank you sir❤
thanks sir
Very good explain
crisply explained!!!

Sir please make video on centrifugal compressor Numerical.
Thanks sir
Thank you sir
It's explained well but only 1 error, V12= V1 - V2 where V12 is Velocity of 1 wrt 2... You are saying Cv+ U1 it should be Cv-U1=C... Other than this, it's excellent...

thank you very much i wish allah like and help you
Hindi me bole
