Do you know an industrial sensor or method to measure air bubbles (sizes and rate) in pressurized pipes?

Does the pressure(-600 mmHg) affects pH?

When I conducted the degassing experiment using decompression under anaerobic condition(and I used ferrous based chelating agent), the oxidized ferric were observerd. So, could you tell me the...

Is there any test to determine the cardiovascular risk of patients with obesity? from the perspective of obesity?

We found tests to determine cardiovascular risk taking into account lipid profile, blood pressure, age, history of diabetes, other laboratories. But when weight is involved, there is a paradox. I...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...

Why almost every element would be metallized in sufficiently high pressure and low temperature?

(This statement is from wikipedia, BTW). What is so special about metallic bond that is limiting high-P low-T state of a matter (as long as individual atoms exist, not white dwarf of neutron star...

Gennadi Lukyanov

I have questions to clarify: 1. Is the pipe metal or plastic? 2. The internal diameter of the pipe and the estimated size of the bubble. 3. Pressure and flow rate in the pipe (or Re)

Mohammad Bijankhan

Dear Gennadi,

Thank you for your reply.

The pipe is metal with the internal diameter of 200 mm. Flow rate of 10 to 20 l/s with a maximum pressure of between 0.2 to 0.5 bar is anticipated.

No idea for the bubble sizes. They are produced due to votices formed at the pump inlet.
