He is the best teacher undoubtedly. I have gone through the lectures of fluid mechanics by SOM sir too. He is truly a gem for us.

Dhanyawad Sir

[@surendrababu1939]

Excellent sir
Your teaching is super sir

[@itzmeurfrnd3902]

Is the power input or output power which,was plotted against discharge

[@user-kq2wp9zn4m]

Thank you for a good explanation!

[@jasper78138]

Why power graph doesnot start from origin???

[@pradeepkumar-ob9rr]

thank you sir very well explained

[@Vickysahu0092]

Can anyone explain, how the actual head is developed,Ha ( curve V ) even if discharge is zero ?

[@banglarahasyagolpo8783]

Apply eular equation to calculate head developed by the pump considering blade geometry,It is He=A-bQ where Q is flowrate.at Q =0 at the starting pump has some head.that ia called shut off head.actual curve is parabolic.basically at the starting of pump, centrifugal head must be given to the impeller to suck the liquid and start the flow.

nice ...exp...

[@raushankrishanan4589]

Luv u sir

[@amitupadhyay5603]

thank you so much sir........

[@bashamsk1288]

If i keep rpm ,area constant how can i increase discharge

[@maheshwarisrivastava5157]

By decreasing net head
wQH=constant

[@rahuljha141]

no volume

[@MrJoymalakar]

no sound

[@parimalshah6758]

why sound not comining?

[@ravikantkumar9054]

If you use a correct earphone then you will must be listen.

[@samitavaroy6813]

yes sound
