How to determine the velocity, pressure drop and flow rate of air in Pipe

[ullas2711]

Dear All,
I would like to know if there are any equations using which we can calculate the velocity, pressure drop and flow rate of air in pipe. Whether the same formulas used for water can be applied to air? Also please let me know whether elevation difference makes any difference to the pressure loss in case of air as it does in case of liquids.
Thanks in advance

Yes, there are equations. Most people with a "Mechanical Engineer" designation would have been exposed to them prior to their Junior Year in college. Your question feels like homework to me so I don't think I'll go further.

"Belief" is the acceptance of an hypotheses in the absence of data.
"Prejudice" is having an opinion not supported by the preponderance of the data.
"Knowledge" is only found through the accumulation and analysis of data.

You might invest in a Crane Technical Paper 410 Flow of Fluids Through Valves, Fittings and Pipe. It has said equations for both air and water. They are different.

Ditto to Crane.

One good source is a handbook titled Fan Engineering published by Buffalo Forge Company Buffalo, New York.

I wish I had Crane's TP410 when I was in college!

Good luck,
