    Can we shift efficiency to x - Axis and Q to y-axis the graph will be still same right ?

    Great video, but isn't it important to note that the pump will operate at the point where the pump curve intersects the system curve? Your video implies the pump will operate at the most efficient point. You really need to determine the discharge head your pump is operating against, and find the most efficient pump impeller to use. Again, great video!

      please can some one can guide me i want to do research of already installed pumps and want to take these curves what test we have to perform what are the procedure for that testing ... and want to find extra energy which i am wasting.. my supervisor give me the topic i have no idea for testing procedure if you know please guide me .. shoaibahmeduet@gmail.com just send me the procedure in pdf or any source thanks

    Are those above given curves valid only for particular diameter of impellar only?

      yes, a different diameter of impellar will change pressure to flow ratio

  • @sayalaperbandel
    @sayalaperbandel 4 ปีที่แล้ว

    You mean if i have pump and want to move water
    Its not good to have zero pressure
    Give it valve and make back pressure a little bit until peak efficiency point
    Back pressure is good at some point
    Zero pressure is not efficient

    Why head max at zero discharge

    • @AmericanWaterCollege
      @AmericanWaterCollege  6 ปีที่แล้ว +6

      A centrifugal pump is only capable of producing a certain amount of discharge pressure (Head) based on its design. If the pressure (head) the pump is pumping against is equal to its maximum discharge head, there will be no flow. As the head the pump is pumping against lowers, flow will increase as shown on the Head (green) curve in this example. Thanks for the question. Hope this helps.

    • @abdullahasiri1908
      @abdullahasiri1908 5 ปีที่แล้ว +2

      Increasing the flow means increasing the kinetic head.Kinetic head increment causes the discharge head to decrease because pressure energy is converted to kinetic energy and vise versa. I believe these curves are plotted for constant speed pumps with flow adjustment using a control valve. We may need to look at variable speed pumps which are, from my perspective, more efficient and have different pumping characteristics.

      Well, I got it. Arranging dissimilar pump in series/parallel may lead problems (especially when the other pump are larger). Risky

      @govindrajput3814 5 ปีที่แล้ว +1

      due to insufficient volume of water feeding into other pumps it will lead to cavitation
