air compressor Q=2,6m^3/min D(diameter)=50mm P(pressure)=7,5Bar V=Q/A ---> V=4*(2,6/60)/(3,14*0,05^2) V=22,08m/s MACH=22,08/340=0,064 Can i use incompressible flow equations(DARCY-WEİSBACH)?

I found a formula from atlas copco manual p1-p2=(450*(q^1,85)*L)/((d^5)*p) q=air flow (l/s) d=internal pipe diameter(mm) l=length of the pipe bar(a) p=absolute initial pressure atlas copco products air compressor.Can i use this formula to calculate pressure drop in pipeline?

hi friends, I am confused with incompressible and compressible flow.Can i use moody diagram for air compressor.How can i calculate pressure drop in pipe.
