The air-standard efficiency of an Otto cycle is given by which one of the following equations? Where rc is the compression ratio, γ = adiabatic index.
1
\(1 - \frac{1}{{r_c^{\gamma - 1}}}\)
2
\(1 - \frac{1}{{r_c^{\gamma + 1}}}\)
3
\(2 - \frac{1}{{r_c^{\gamma - 1}}}\)
4
\(1 + \frac{1}{{r_c^{\gamma - 1}}}\)
