Is there an observable trend or difference between all the flowmeters readings (venturi, rotameter, and orifice) and the system flow rate (obtained using magnetic or coriolis flowmeters?

Expert Solution

For orifice meter and venturi it is used generally for constant discharge while rotameter is used to measure variable discharge .

In betweens orfice meter and venturi meter coefficient of discharge in orifice meter is high therefore discharge for the same pressure difference discharge measure by orifice meter is less .Hence it is less accurate compare to venturi meter

Now for magnesti flow meter ,it is also called as electromagnetic flow meter.

Following are the advantages of elctro magnetic flow meter

1) doesn't obstruct the flow

2) give complete linear output in the form of voltage

3) reverse flow can be measured

4)very low flow velocity 10^-6 m/s can be meausrme

If all we can observe are things inside the observable universe, how do we know that anything even exists outside this boundary? I can see four ways of solving this problem. 1) We wait a while, the observable universe should get 'larger', so we should be able to observe more. I don't think this is practical though, since telescopes have only existed for a hundred years or so, whereas the age of the universe is many degrees larger. Also, galaxies...
