[@im_anand]

you are so good teacher , ever in my life sir.... I m so glad....

[@pratikv8222]

We must preserve this treasure !!!

[@nikhilshukla8828]

awesome lecture professor thanks a lot ...........may god bless you

[@ShubhamKumar-ly8zv]

Just watch the full video. Worth the time😃

[@shubhamsrivastava2832]

One of the best proffesor

[@AmanKumar-eb6fv]

best of all nptel lectures

[@danialone9756]

I can not understand that, velocity of impeller tip (V2) is supersonics, than,How vaneless diffuser decrease velocity?

[@shazirahmani]

@2641, the recirculatoryflow should be opposite as fluid flows to negative pressure

[@shubhamdasmana218]

thank u sir good work

[@pradhumansinghcharan]

professor suddenly became old ?????

[@himanshusharma3160]

awesome explaination

[@IES_Munish]

Bernoulli equation require modification when applied to compressible flow.

[@issamn.e9032]

Playlist name please

[@jebaangelin2930]

Doesn't continuity eqn and bernoulli's principle apllies only for incompressible fluids

[@jasper78138]

Sahi kaha

[@pasupathynathan.b9356]

if there is no energy gain in diffuser then how there would be the rise in pressure? pressure is also one form of energy which rises temperature of fluid can you explain me sir?

[@alfredogarcia5529]

Pasu pathynathan.B despite the loss of total pressure in the diffuser due to viscosity, the increase in area in the diffuser reduces the air velocity, therefore the dynamic pressure is also reduced but the static pressure is increased. The goal of any kind of compressor is to increase the static pressure .

[@pavanrongala9517]

nice need more

[@anupkumar8220]

Thank you sir.....

[@tejasdesai9687]

why is the pressure called static pressure if the fluid is moving?

[@urmilasharma3983]

Tejas Desai here dynamic word come from static head and dynamic head, static head provided by pressure while dynamic head by velocity

[@alpaciandecatre4385]

The pressure measuring instrument is static relative to the fluid flow ie. the fluid and the pressure measuring instrument are assumed to move together.

[@manav24jan]

static pressure is the pressure experienced when air molecules interact and collide with each other

[@dasambaburao9396]

As per boundary layer theory velocity of the fluid becomes zero at the wall, where pressure measuring instruments are installed, because of zero velocity pressure will be max as per bernouli theory. That's why the name

[@mayur0160]

Can you learn about centrifugal blower

[@pasupathynathan.b9356]

as the area increases pressure reduces (P=force/area) i cant get the correct working of diffuser how the pressure is gained CAN YOU PLEASE EXPLAIN ME SIR?

[@NeerajKumar-jc3by]

Your logic is true in case of solid not in fluids

[@NKASIMKOTANAGARJUNA]

Gud lecture with reasonable justifications

[@NKASIMKOTANAGARJUNA]

Gud lecture with reasonable justifications

[@dasambaburao9396]

Yes u r correct. If area increases pressure decreases. Where as in this case, there is conversion of kinetic energy into pressure energy because of decrease in velocity.

[@1986rkumar]

thank you sir

[@vinayrawat2871]

The stagnation temperature explaination isn't correct.

nice

[@agustin4764]

the tutorial is fine but needed the translation in Spanish, because the market many Latinos (imprtantisimos)

[@GeorgeRon]

Did you try KZbin subtitles , you might get one in Spanish.

[@kishanchauhan6883]

pressure is inversely proportional to area not directly

[@harshkhandelwal5971]

kishan chauhan As area increase, velocity decrease according to continuity equation and pressure is inversely proportional to velocity hence pressure is directly proportional to area

[@excitedinspired9939]

+harsh khandelwal i second on that
