Question: 4 an aircompressor steadily draws air from the atmosphere at...

Question details

4.) An air-compressor steadily draws air from the atmosphere at 300 K and 100 kPa, and discharges at 600 K and 800 kPa. The exit pipe diameter is 0.10 m and the exit flow velocity is 20 m/s. Assume the compressor is insulated. Neglect changes in kinetic and potential energy. Find the compressor mass flow, power & efficiency: m- Given for air: k- 1.4, R-0.287 kJ/kg-K, c 0.718 kJ/kg-K, cp 1.005 kJ/kg-K HINT for SSSF per unit mass use ideal gas properties (h2-h) Winput Extra: Notice Q ~ 0 (adiabatic) and 100% efficiency (reversible) are different concepts! Are the changes in kinetic and potential energy really negligible? (not-0 but almost) How do the compressor and pump analyses differ?
