    I love the juggalo comparison. Fantastic.

    I respect you, sir. I appreciate these videos immensely. As a hard working and inventive entrepreneur, I must say, you have created the path of least resistance to an extremely practical education, on this, and apparently other subjects for so many, and invariably many more to come. I am grateful to you, and regard you as a champion in mind, spirit and action. With that said, I'm sorry someone has apparently given you the absolute worst impression of Juggalos. Hell, maybe even several someones. However, the acts (there are many beyond ICP) associated with this fan-base are the sole guides responsible for countless people having survived extreme emotional stress and murderous or suicidal thoughts. These artists are heroic and brave in ways only ignorance can dismiss, and that is basically the whole point. I have nothing but love for you, and shall continue to subscribe and cherish these lectures. Thank you for all you do

    I saw almost all hydraulic videos in this channel , they are good and useful. Also make a video on hydraulic fittings.

    Is the flowrate (Q) across a flow control valve proportional to the pressure difference (ΔP) across the valve or is the flowrate (Q) proportional to the square root of the pressure difference (√ΔP)? If instead it is a linear relationship, how do achieve this if in general, flowrate (Q) is proportional to square root of pressure difference (√ΔP).

  • @y.s8916

    Suppose I have a control valve whose upstream pressure is fixed. Now if I open the valve, flow increases, you restriction will decrease so pressure downstream will increase. Overall pressure drop will decrease. But how is the flow increasing despite of pressure drop decreasing.

    • @bigbadtech
      @bigbadtech  Před 3 lety

      Downstream pressure is a load induced phenomenon.

  • @y.s8916
    @y.s8916 Před 3 lety

    How are you controlling the output pressure? By varying the valve opening?

  • @John-dp3ln

    Shouldn't the flow control be on the discharge side of the cylinder? Is either way acceptable? What are the advantages of each configuration?

    • @bigbadtech
      @bigbadtech  Před 8 lety

      +John Griffin Check out this lecture: czcams.com/video/VFtRNAu3_wg/video.html
      it explains several common flow control methods

  • @Mech.Masters
    @Mech.Masters Před 6 lety

    Normally flow control is achieved by reducing the cross section through which the oil is flowing. But continuity equation states that product of Area x velocity is constant through out the tube. So when area is reduced, velocity increases and flow should remain the same. Then how does reducing the cross section helps us in flow control?

    • @bigbadtech
      @bigbadtech  Před 6 lety +1

      There is not continuity. A relief path exists. Any flow not traveling through the flow control valve is bypassed to tank. That's really the fundamental takeaway about restriction style flow control valves. Also understand continuity assumes laminar flow. In reality you cannot expect to force 500gpm through a 1/4" diameter tube without it getting a little turbulent.

  • @mannyfernandez7028

    very informative . Reducing flow by a valve is cheap and efficient , what if i reduce the speed of a motor by a vfd will i get the same resulting pressure ? thanks in advance.

    • @bigbadtech
      @bigbadtech  Před 5 lety +1

      Remember that pressure is a load induced phenomenon. As long as the load induced pressure is inside the range of the pump at the reduced rotational speed it should work.

    Sooner or later thoes juggalos are going to see your video of you down talking them, and they will throw you in hell's pit!

  • @ahmeddahab8907
    @ahmeddahab8907 Před 5 lety

    Hi Sir
    I want to ask a question, How the flow rate across the flow control valve increases by increasing the pressure difference across the valve, however when the pressure increases upstream the relief valve opens more and more fluid goes through ?
    the logic say when the pressure difference increase , less flow across the valve.
    Am i right or there is a false understanding in any part ?

  • @shamimahmed9028
    @shamimahmed9028 Před 7 lety

    Sir,It would have been much better if you mention the key characteristics or important informations in written form in the videos,its tough to catch all the informations you says....Btw the video is very helpful,thanks.

    • @bigbadtech
      @bigbadtech  Před 7 lety +1

      Agreed. This is one of my earlier videos and I've learned to include a better objectives summary. Additionally I've started producing free study guides. Check out some of the new ones for examples. Glad you're making use of this material!

  • @fahdhatem7535
    @fahdhatem7535 Před 7 lety

    I don`t understand , the positive displacement pump delivers a constant discharge say 2 gpm ,and after the flow control valve it becomes say 1 gpm ,where does the other gallon go ?? and many thanks for the video

    • @bigbadtech
      @bigbadtech  Před 7 lety +2

      The excess is diverted to tank through the pressure relief valve.

    How does pressure drop reduces flow rate ?

  • @Naveenkumar-og7bw
    @Naveenkumar-og7bw Před 6 lety

    I have one question how you decided for 500psi input output will be 300psi

    • @bigbadtech
      @bigbadtech  Před 6 lety

      In this application we're just assuming the load induced pressure will be 300psi.

    • @Naveenkumar-og7bw
      @Naveenkumar-og7bw Před 6 lety

      Thanks for quick reply.please can you tell how to design output pressure.this will help me a lot

    • @bigbadtech
      @bigbadtech  Před 6 lety

      Output pressure is dependent upon:
      1) applied load
      2) actuator dimensions
