Dear Mr Agarwal:

Many thanks for the article. It is very very useful to me.

Where do you get the Equivalent Length for component such as bends or elbows??

Is it good to use the "CRANE, Through Valve, Fittings and Pipes" reference??

Thank you so much.

Article: Theory and Design of Dilute Phase Pneumatic Conveying Systems

Dear Amrit,

The paper is a straight forward approach to the subject and is easy to follow, however,

- are there inconsistencies in the attached worksheet?

-- the roughness factor used seems to be 0.00015 instead of 0.0005

-- the pipe section in worksheet 2 section 9 was moved to section 10 in worksheet 3

- I do not feel comfortable when a pressure is given as mass/area rather than force/area, but this is just my problem with Newtons/sqm.

- Is it possible that the calculation method

-- does not represent the pressure drop minimum at the point of saltation velocity properly?

-- is wrong in regard to assuming a constant product friction multiplier over the whole velocity range?

- I miss some limits within which the formulae are applicable, like

-- maximum solid/gas ratio

-- minimum velocity depending on different products and particle sizes

- The Zenz equation also considers acceleration of the carrier gas, however, though the dp is small, it is not listed in the calculation table.

- What are common criterion for stepping up a pipe? Shall this be based on dynamic gas pressure, same pressure ratio for same diameter sections, Reynold number minimum, Froude number minimum?

- The gas pressure drop for bends can be calculated fairly accurately with a factor of 0.12. Is there a different way to calculate the pressure drop due to the product rather than using an equivalent length? Solids deceleration to xx% gas speed and re-acceleration as per W*Vp/4640 might be an option.

I have concerns whether the approach is as "easy" to apply to reality as it looks. I appreciate your comments ;-)

Best regards,

Dear Amrit,

Sven has seriously studied your article and spreadsheet calculation, resulting in a series of valuable remarks.

It would be a pity, if these remarks stay open.

Exchanging and sharing knowledge and experience as well as improving the common understanding of the technology of pneumatic conveying is one of the main goals of this forum

Therefore, it would be very interesting to the forum (and to Sven) to know the answers to his questions, which you undoubtedly have available.

Best regards
