The following figure shows the P-V diagram of the diesel cycle. V1, V2, V3, V4 are the volumes at the state point 1, 2, 3, 4, respectively. Which of the following is true for this cycle? [r = Compression ratio, q = Cut-off ratio.]
1
\(r={\frac{V_{1}}{V_{3}}}\ ;\,q={\frac{V_{3}}{V_{2}}}\)
2
\(r={\frac{V_{1}}{V_{2}}}\ ;\,q={\frac{V_{3}}{V_{1}}}\)
3
\(r={\frac{V_{1}}{V_{2}}}\ ;\,q={\frac{V_{3}}{V_{2}}}\)
4
\(r={\frac{V_{1}}{V_{3}}}\ ;\,q={\frac{V_{4}}{V_{3}}}\)
