How to calculate the pressure drop across air filters like HEPA and Activated Charcoal filter sheets?

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...

Hello Rajdeep,

Looking at Ergun's equation, it seems appropriate. However, this applies for packed beds. So I suggest that you first calculate values using Ergun's equation (provided that all parameters are given). Then try to create a simple experimental set-up for the HEPA filter and AC filter using fans (to simulate the air stream), and pressure gauges. This way you could compare the values.

btw, for what application are you intending it would be used?

For reference
