Problem
A rigid steel bottle, V = 0.25 m3, contains air at 100 kPa, 300 K. The bottle is now charged with air from a line at 260 K, 6 MPa to a bottle pressure of 5 MPa, state 2, and the valve is closed. Assume that the process is adiabatic and the charge is always uniform. In storage, the bottle slowly returns to room temperature at 300 K, state 3. Find the final mass, the temperature T2, the final pressure P3, the heat transfer 1Q3, and the total entropy generation.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
