Comments on Mr. Agarwal's Theory and design of Dilute Phase Pneumatic Conveying...

Dear all,

After kindly receiving a copy of Mr. Argawal's article, I am trying to build up the model in Excel.

Comments so far:

In spreadsheet nº1 'Imput data' I find useful to have a set of cells with inlet air viscosity, Reynolds number and inlet pressure.

Above all and so far, I find trouble with W, which is referred to as 'Solids mass velocity (lbs/sec·ft2) in page 18, solids line loading (lbs/sec·ft2) in page 19, and solids conveying rate (lbs/hr) in page 22 (input spreadsheet).

Is there a possible inconsistency in the latter? I can not manage to achieve the correct number for solids acceleration (W·Vp/4640) in the spreadsheet using the given formulae.

Also, In page 21, in order to calculate solids acceleration, it is said to enter #C3 for W (I assume from the Input data spreadsheet) but this seems incorrect. Same thing happens with Vp and #B10, it should be #B11.

I am very interested in making thes excel work.

Regards,
