Develop a computer program or use a spreadsheet or equation solver to calculate the Otto ASC thermal efficiency as the compression ratio ranges from 1.00 to 12.0 for the following values of k: 1.40, 1.35, 1.30, 1.25, and 1.20 (note that values of k less than 1.40 give an approximate hot ASC result).
Plot these results (either manually or with a computer) with the thermal efficiency on the vertical axis and the compression ratio on the horizontal axis, using k as a parameter for the family of curves. Utilize at least 25 points per curve.
