(Answered) High-velocity air at 20-c and 100 kpa absolute flows in a

Academics

High-velocity air at 20-C and 100 kPa absolute flows in a conduit at 600 m=s. It undergoes a sudden change (a shock wave) to 263 m=s and 438-C with no change in conduit dimensions. Determine the mass flux and the downstream pressure if the conduit cross-sectional area is 500 cm2.
