    Hi, Nick, I think you should plus(+) the friction loss on the discharge side rather than minus(-). :)

    I am recently working under training in Gas Processing Project for SRU and TGTU. We have a lot of pumps and material transfer work to do. And I found this course is very simple and informative that will helps a lot in Hydraulic calculation.
    Hope you can also instructor about vessel sizing, pipe sizing, valve hydraulic calculation too.
    A lot of love and respect to you Mr. Nick.

    Hi. If we have pressure gauges on an existing system on the discharge and the suction, we can just look at them right? We don't need to calculate, am I understanding it correctly?

    Hi Nick. Thank you very much for your video.
    I have a question, if i put a pressure gauge at a suction side of the pump. If I substract the vapor pressure of the liquid from the reading of pressure gauge will I get NPSHA?
    Thank you again.

    Hi, Mr.Nick How to know if the pump requires minimum recirculation line? I don't understand clearly. I have this idea that this minimum recirculation line is related to turndown ratio advised by vendor. Could you explain clearly?

    The water can deliver at 50m Head from a pump, if we can use glycol instead of water in the same pump. Is any variation in head

    • @nicksengineering987
      @nicksengineering987  Рік тому

      The Head is the same assumed that the viscosity and pump speed are the same. of course, the denser fluid will affect pump efficiency due to hydraulic friction loss, motor power efficiency, etc.

    I have been provided with 3 bar water from the main city distribution , and I need to deliver water for 7 floor (40m approximately) , I will use manifolds in each floor for construction.. what should be pipe dia? Pressure on manifold? Pump capacity? Everyone is showing a water tank from low level to another water tank at high level , this is easy .. what about horizontal pipe on remote line?
