A steady-flow compressor is used to compress helium from 15 psia and 70°F at the inlet to 200 psia and 600°F at the outlet. The outlet area and velocity are 0.01 ft2 and 100 ft/s, respectively, and the inlet velocity is 54 ft/s. Determine the mass flow rate and the inlet area. The gas constant of helium is R = 2.6809 psia·ft3/lbm·R.

Respuesta :

Answer:

mass flow rate = 7,04*10^-2 Lbm/s

Inlet area= 0,123 ft^2

Explanation:

The explanation can be found in the attached picture

The mass flow rate and the inlet area were calculated under the assumption that the Helium gas behaves as an ideal gas.
