    What is the General Frequency of Unsteady Pressure in a 2.2 mm Pipe?

    They all are assumptions, maybe not realistic. Is it a must to have turbulent flow when pressure is unsteady? I mean in transmission lines.

    What is the General Frequency of Unsteady Pressure in a 2.2 mm Pipe?

    It's fluid mechanic labarotary pipes. I just did assume. I want to see what would be pressure loses under the worst condition so on. Please I need some help about it also

    What is the General Frequency of Unsteady Pressure in a 2.2 mm Pipe?

    During measurement of pressure differences by the using orifice and an electronic transducer, we can have some oscillation on diaphragm, I try to define this effect by the calculating pressure drop from vena contracta to transducer. I say that oscillation is 30 percent (maybe its too much, if...

    What is the General Frequency of Unsteady Pressure in a 2.2 mm Pipe?

    Hello everyone; What is the general frequency of unsteady pressure when we measure by the using transducer and diameter of pipe inside can be 2.2 mm? Can someone provide a proff also ? I mean scientific paper. Thank you

    Accuracy of Transducer: Measurement in Pascal?

    Hello everyone; My transducer manufacturer says that the accuracy of the pressure measurement device is 0.5% in full scale of PSI. However, I don't use Psi but Pascal. Is it the same value for pascal as well? When I make measurement I will get 0.5% error in pascal too? Thank you.

    Venturi, Orifice and Nozzle

    Hello everyone. When I try to do mass flow systematic uncertainty estimation for venturi nozzle and orifice, I am getting the biggest error from venturi nozzle. What is the reason for it? ( Why coefficient of velocity of venturi nozzle is too big compared to orifice and nozzle.)
