Both the Characteristic Curve and Efficiency Curve is available with the Equipment Manufacturer and it is unique for each pump, the operating curve is graphically established by studying the operational parameters and hence drawing out the Engineering Bernoulli Equation.
If the actual head is extremely less at high flowrate as compared to Rated Head, either the Pump is malfunctioning or there is a leakage for easy passage of the liquid right after the flowmeter which never really lets the head or pressure build up in the Pipeline whereas the Flowrate increases due to extra allowance of liquid passage through leakage.
@@LifeBeyondBusiness No sir pump is fine, but what if we want much lesser head and higher flow. I know efficiency will decrease. But i want to know upto what extent we can increase the rate by decreasing required head.
That's the whole point, as you correctly said, head loss occurs with increases in velocity, doesn't it imply that head loss is a function of v which reflects itself in Head. Let Head Loss = dH infinitesimal, dH = function of v (as you have said), so it clearly implies that H = function of v as well, and the integration ends of in a quadratic equation h vs q. If on the other hand, h would have been a liner function of q, dH/dq would have been a constant and the graph of h vs q would be linear which is not the case!

খুব ভালো লাগলো। বিশেষ করে শেখানোর পদ্ধতিটা। সুন্দর। চালিয়ে যাও মিস্টার চেল।
Thank you ♥️
nice one! i invite u makan prata bawang.. thumbs up!
Nice video..incorparating videos can make it better
Hi,
Which submersible pump should be installed for 400ft borewell with 1inch yield.
Borewell size is 7 inch
This is very purpose specific, you should refer to similar industrial practices to figure out the type of pump used in those
Where to find the pump curves
Both the Characteristic Curve and Efficiency Curve is available with the Equipment Manufacturer and it is unique for each pump, the operating curve is graphically established by studying the operational parameters and hence drawing out the Engineering Bernoulli Equation.
What will happen when pump is run outside performance curve. Like what will happen when head tends towrds zero or very less than rated head
If the actual head is extremely less at high flowrate as compared to Rated Head, either the Pump is malfunctioning or there is a leakage for easy passage of the liquid right after the flowmeter which never really lets the head or pressure build up in the Pipeline whereas the Flowrate increases due to extra allowance of liquid passage through leakage.

Under Normal Operating Conditions, if everything is fine Head of the Pump is directly proportional to (Sqare of Flowrate)
So as you increase Operating Flowrate, Head will automatically increase

audio not clear
This is very large to understand it is not in simple form it could be little bit simple means we can understand
Feedback Noted! Thanks
I'm even more confused now
Head is linearly proportional to q( h=c1-c2*q) and the shape is bending due head loss with increase in velocity. Your explanation is wrong
That's the whole point, as you correctly said, head loss occurs with increases in velocity, doesn't it imply that head loss is a function of v which reflects itself in Head. Let Head Loss = dH infinitesimal, dH = function of v (as you have said), so it clearly implies that H = function of v as well, and the integration ends of in a quadratic equation h vs q.

Are u copying style of anyone stopshitt
No!
