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.
