    Does back pressure give incorrect flow reading?

    flow = a2*sqrt(2*ΔP/(density*(1-pow((a2/a1),2)))); where Q is the flowrate, ΔP is the pressure difference between the two nozzles, A1 and A2 the outer and inner diameters respectively, and ρ the density. A higher reading was...

    Does back pressure give incorrect flow reading?

    No, it is attached to nozzles present on each side of the constriction.

    Does back pressure give incorrect flow reading?

    I have to build a digital peak flow meter. I have two models based on calculations ( ideal). I have noticed that the flow rate on the model with a tighter constriction has a greater value than that of a much broader constriction. While testing it out, i noticed air resistance from the first...

    Efficient Venturi Tube Calibration for Digital Peak Flowmeters | Thesis Design

    Forgot to add, that it's used to check asthma parameters

    Efficient Venturi Tube Calibration for Digital Peak Flowmeters | Thesis Design

    But it's airflow, wouldn't the nature of the fluid ( being water or any other liquid) impact calibration?

    Efficient Venturi Tube Calibration for Digital Peak Flowmeters | Thesis Design

    I've designed a venturi tube for my thesis ( Design of a digital peak flowmeter). I was wondering if there was a way to calibrate the flowrate, without using a measured flowrate producing device. The current error is about 12.3%. Theoretical 610L/min vs experimental 535L/min.

    Are these two terms synonymous? or not

    How to measure flowrate using a differential pressure sensor

    I believe flow rate = cross sectional area x fluid velocity Im not sure about the pressure vs velocity pressure = force/area force= mass x acceleration velocity = integral of acceleration so pressure= ( mass x velocity x time) / area

    How to measure flowrate using a differential pressure sensor

    Initially i thought of just measuring the pressure at one of the inlet ( using it as a gauge pressure sensor). Hence, i would get the pressure readings and then just graph them. But it does not tell me the volume metric flow, and that data probably isn't useful. Differential pressure sensor...

    How to measure flowrate using a differential pressure sensor

    I have to build a digital peak flow meter. I ve read that you can measure the volume metric flow rate using a differential pressure sensor. H ow do i go about doing so. The peak flow meter will be used to measure asthma.
