Air in a compressor P100 psi atmosphere T298K is discharged

Air in a compressor (P=100 psi atmosphere, T=298K) is discharged through a 3/8” diameter hose. Ignoring friction, estimate the mass flow rate and air density at the 3/8” throat.

Solution

solution

P = R T

= P / ( R T )

   = 689476 / ( 287 X 298 )

= 8.06 kg/m3
