main flow has mass flow rate of 1.1 kg/s and temperature of 600 is solved as a compressible flow.operating pressure is 101325.gauge pressure in pressure outlet boundary conditions is set as 0.nafter flow is solved,ndensity is about 0.57,ninlet velocity is about 60 m/s,nin the elbow velocity is about 110 m/s,nbig part of domain has velocity of about 50 m/s,nmach number is between 0.004 to 0.25.nare they correct and logical?.n
