Which of the following is the correct relationship between γ and Cv?(a) Cv=R\(\frac{\gamma}{\gamma-1}\)(b) Cv=\(\frac{R}{\gamma-1}\)(c) Cv=\(\frac{R}{\gamma+1}\)(d) Cv=R\(\frac{\gamma}{\gamma\mp1}\)This question was addressed to me during an interview.Question is from Measurement of Airflow Characteristics in chapter Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

Correct option is (B) CV=\(\frac{R}{\gamma-1}\)

The explanation: Cv=\(\frac{R}{\gamma-1}\) is the correct relationship between γ and Cv where R= characteristic gas constant, γ is the ratio of SPECIFIC HEAT at constant pressure to that of specific heat at constant VOLUME and Cv is the specific heat at constant volume.
