Problem 7-Analysis of a compressor 0.6 kg/s of CO₂ at 100 kPa and 27°C in an industrial installation is transported using a compressor. The exit conditions from the compressor are 600 kPa and 137°C. a. Starting with the general mass and energy conservation equations compute the power that this compressor will require for continuous steady operation, in kW. You may assume that the compressor is adiabatic and that the changes in kinetic and potential energy are negligible. b. Now, you want to be realistic. This compressor is not adiabatic, and some heat is transferred to the surroundings. Do you expect the power needed for the same input and output condition to be larger or smaller than your answer in part (a)? Justify your answer using thermodynamic principles.

Problem 7- Analysis of a
compressor
0.6 kg/s of CO₂ at 100 kPa and 27°C in an industrial installation is transported using a
compressor. The exit conditions from the compressor are 600 kPa and 137°C.
a. Starting with the general mass and energy conservation equations compute the power
that this compressor will require for continuous steady operation, in kW. You may
assume that the compressor is adiabatic and that the changes in kinetic and potential
energy are negligible.
b. Now, you want to be realistic. This compressor is not adiabatic, and some heat is
transferred to the surroundings. Do you expect the power needed for the same input
and output condition to be larger or smaller than your answer in part (a)? Justify your
answer using thermodynamic principles.

Good morning interns, This is Ms. Gorman from the sales department. We have just secured a new, multi-million-dollar account! We are so good here in the sales department of Heavy-Duty Box Inc. The manufacturing director, Mr. Tsosie, has instructed me to send this problem out to all of you as this will be a deciding factor in which of you get offered the full-time positions available at the end of the internship! Our new client, Beastie Bearings Inc., needs the heaviest duty box we make here at Heavy-Duty Box for their bearings. The following email from Ms. Venegas from Beastie Bearings provides the information you will need. Remember, our mark-up sales price is 150% of what it costs us to manufacture the product. The cheaper it is for us to produce the box, the lower the cost for our client. There is also a grading rubric attached that Mr. Tsosie will be utilizing in evaluating your work. I would advise you to follow it well if you want a position! Good luck interns, Ms. Frances…
