    5. The Martian atmosphere consists mainly of carbon dioxide with an average surface pressure of 700. Pa and an average temperature of -57 °C. A piston-based compressor is being designed to take ambient Martian gas and increase the pressure to 2.2 bar before it is processed for rocket fuel. CO2 is not CPG at these conditions -- you can assume it to ONLY be a TPG gas. a. Assuming the Mars atmosphere is pure CO2 and the compression process is...
