By increasing Q, you are increasing the velocity. For real fluid, increasing velocity results in decreasing the head. Because, for greater velocity, head loss by friction is greater as they are proportional.
Sir i think pump develop pressure so increase liquid pressure and reaches to it's temperatures so vapours pressure will increase so available pump suction pressure will be less than vapours pressure of liquid so chances to Cavitation

Good explanation Tnx
God bless your efforts
Great video ❤. Very informative
sir i think power consumption in amps not in kw.
How to read KSB multitec pump curves? I need a guide..
❤
By increasing Q, Why H is reducing? Technical reason...
do practically this in your home by flexible pipe then you'll find the reasons very simple

I think, if Q decreases, npsh will decrease. So possibility of cavitation will increase. am I right sir?
Absolutely right! Could you tell why will it happen?

In our case shut off head is 60m at 0 flowrate .am I right sir?
yes!
@@Coreengineers made video on cause and effect
You are just telling how to read the graph. Please explain how the graph/curve is obtained.
60m
How I will calculate efficiency if Q and H are in this condition that are not intersecting efficiency curve?
mainly it consist the that one as well. the curve which I shared individually was for the reference purpose to elaborate the each curve.
Ohp
Pls sir hindi me bhi ye vido chyae
Pls educate yourself
Shut off head= 60m
