Question #109154

air enters a compressor with a density of 1.2 kg/m3 at mean velocity of 4 m/s in the 6 cm x 6 cm square inlet duct. air is discharged from the compressor with a mean velocity of 3 m/s in a 5 cm diameter circular pipe. determine the mass flow rate and the density at outlet?

Expert's answer

Given:-

Find the mass flow rate and the density at outlet.

Now,

Therefore,

Conservation of mass between section (1) and (2).

so,

Hence, the density at section (2) .

Answer:-

The mass flow rate and the density at outlet.
