Study of the relationship between fluid velocity and time

[derekteo0710]

I need to study the relationship between fluid velocity and time. The fluid is kept in a big open tank before passing through a water tunnel. The velocity is set at 0.07m/s and the fluid is at rest initially.

I would like to see the relationship between the fluid velocity and time during the period when the fluid is accelerated to the desired speed.

So far I had through of using a probe type flow meter to observe the different fluid velocities at different times until it reaches a steady velocity of 0.07.

Does anyone know is there a better or more efficient way of doing this study?

One approach you could take is to use a particle image velocimetry (PIV) system to measure the velocity of the fluid over time. PIV works by taking two images of particles suspended in the fluid at different times and then tracking the particles to calculate the velocity. This method would allow you to measure the velocity of the fluid at various points over time and get an accurate picture of how the velocity changes. You could then plot this data to see the relationship between fluid velocity and time.
