Re: Pressure Correlation!
Dear Rahul,
The correlation between mass flow and pressure is obvious.
A higher mass flow causes a higher Solids to Air ratio (SLR) and a higher SLR causes a higher pressure drop.
Although this correlation is very much depending on the product properties and (less) depending on the ambient temperature and -pressure.
This correlation is what all the pneumatic conveying experts want to calculate.

Solids Pressure Drop Co-Relation
Rahul,
For this co-relation you may refer to my article "Theory and Design of Dilute Phase Pneumatic Conveying Systems". This article describes in detail how to calculate pressure drop due to the flow of solids in a pneumatic conveying line. If you still have questions, feel free to contact me.

Re: Pressure Correlation!
Dear Teus and Amrit,
Thank you for your replies.
Question for Teus:
my aim is to know about the mass flow rate of the solids. I am interested in knowing the consistency of the solids flow rate. So, keeping the gas flow rate constant, can i conclude that if my measured pressure drop is constant, i have a uniform flow?
Is there a formula which can show the relation between the SLR and pressure drop?
Thanks in advance.
With best regards,

Re: Pressure Correlation!
Dear Rahul,
You are correct in your assumption that, if the air mass flow is constant (under constant
conditions) and the pressure drop is constant, then the product mass flow rate should also be constant, as long as the product properties for pneumatic conveying are constant.
In other words: If everything is constant, then the monitored value is also constant.
The relation SLR=function (pressure drop) can be calculated with the method, described in the aforementioned article.
Checking the actual performance against the calculations is advised.

Pressure correlation!
Dear all,
I want to measure solids flow rate in gas suspension (pneumatic conveying). In an article, it was mentioned that there is a correlation between mass flow rate of solids and pressure drop in the system. Does any one know about such correlation? If so, could you enlighten me on that?
Many thanks in advance.
Regards,
Rahul ■
