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.

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.
Why power graph doesnot start from origin???
Is the power input or output power which,was plotted against discharge
Excellent sir
Your teaching is super sir
Dhanyawad Sir
Can anyone explain, how the actual head is developed,Ha ( curve V ) even if discharge is zero ?

Thank you for a good explanation!
thank you sir very well explained
If i keep rpm ,area constant how can i increase discharge
By decreasing net head
wQH=constant
nice ...exp...
thank you so much sir........
Luv u sir
no sound
why sound not comining?
If you use a correct earphone then you will must be listen.
yes sound
no volume
