QUESTION:
Air is compressed from 20 psia and 708F to 150 psia in a compressor. The compressor is operated such that the air temperature remains constant. Calculate the change in the specific volume of air as it passes through this compressor.
ANSWER:Step 1 of 3
Air is compressed isothermally in a compressor.
The change in the specific volume of air is to be determined. We assume that under specified conditions, air behaves as an ideal gas.
The gas constant of air is (Table A-1E).
