Compressible Gas Pressure Drop Reference
Compressible Gas Pressure Drop Reference
(OP)
Hi,
I am looking for a reference for a compressible gas pressure drop method.
The method calculates a critical value based on specific heat ratio and a dimensionless Mach number (using superficial mass flow). This critical value is then compared to an actual value (8f/d).
The relationship between the critical and actual values then determines where a sub, critical or super critical pressure drop equation is performed.
Anyone help?

a) calculate gas speed of sound based on cp/cv
b) calculate actual velocity (based on mass flow and density)
c) compare values and for subcritical flows adopt specific correlations (there are many of these)...
but perhaps I misunderstand the question...
