Compressor efficiency

1.Create a compressor performance chart with delivery pressure on the ‘ ’ axis,
shaft power as the left-hand ‘ ’ axis and mass flow rate on the right-hand ‘ ’ axis.

2. Create a compressor efficiency chart with delivery pressure on the ‘ ’ axis, and
   with both the mechanical efficiency and the isothermal efficiency (as percentages)
   on the ‘ ’ axis.
3. Explain how the system divides the electrical input power into other types of
   energy.
4. Comment on how and why the values of the two efficiencies vary with delivery
   pressure.
