- In this task, you are suggesting a suitable design for a compressor to be used for gas power plant. You client has asked you to suggest a design for a compressor, where air is compressed from 100 kPa and 30℃ to 10 bar. Prepare a technical design report using following criteria in your design To optimise the final temperature of the gas, you are asked to use various polytrophic compression process. Calculate the final temperature when the process is: Isothermal, Polytropically (n=1.2), Adiabatically Polytropically (n=1.6). Comment on your findings and recommend appropriate process for compression by calculating work input.Thermodynamics subject. Pleas show the complete and step by step solution. A vessel of 0.058m3 capacity is well insulated and is divided equally by a rigid conducting diaphragm. Initially both halves contain air pressure of 137.8kPa and 413.4kPa and temperatures of 27C and 177C respectively. What is the increase of entropy of the system in kJ/C?K=519 A 1.5m diameter spherical balloon containing air at (K + 10) kPa is cooled such that the volume is reduced by 25%. For the process, the pressure is proportional to the square of the sphere’s diameter. What is the work done by the surrounding?
