Did Dr confuse the values of source to sink? because for a source the stream function is positive. (From the last lecture)

[@riturajanand7133]

please refer s.k som book, you will get the solution of your doubt......

[@jayanthchanagani9530]

@@dddghddghjhnbgn can you explain the convention pls?

[@dxfire7865]

Sir now you completed your degree can I know where are you now ?.Like I am also a mechanical engineering student currently in my second semester and I am little bit confused about my career.

Is it possible for irrotational vortex vorticity is zero but circulation still exist? As sir taken in case of rotating cylinder in uniform flow..

[@monishreddy1797]

circulation is the surface integral of vorticity. So circulation becomes zero if vorticity is zero

[@priyanujsarmah2499]

how can circulation divided by (4*pi*a*u) be greater than one? since it is equal to sine thita which can never be greater than 1?

[@akr2967]

Sir tells dat it is impossible case

[@vivekshanbhag786]

it's impossible case hence stagnation point doesn't occur on surface , rather at some distance from the surface

[@sahilgajbhiye0656]

ty very much sir

[@shawnmcelwain7230]

the resolution is awful for the year this was published but the lecture is awesome.

[@MyThundermuffin]

This lecture was recorded in the year 1997

[@gadhiyajaimin7683]

Streamline never intersect itself then what about 40:30..?

[@vivekshanbhag786]

At stagnation point, velocity being zero, you can't draw tangent to check velocity hence they can intersect

[@riturajanand7133]

sir has said like at stagnation point particle has zero-velocity, that means if the particle flowing from upstream to downstream all comes to rest at the stagnation point, then why it forms a circular streamline..........And there will be no streamline after stagnation point for psi=0...................all particle is coming to rest at stagnation point......

[@riturajanand7133]

in this lecture, sir has done a lot of sign mistakes...............

[@AdityaRaj-bq7dz]

Waste, misleading, too many wrong signs resulting in wrong answers, don't watch

[@yesican--143]

Read between the lines.

[@surajmg777]

Go watch some unqualified bihari teaching fluid mechanics then
