Which of the following is the correct relationship between R and Cp?(a) R=Cp\(\frac{\gamma-1}{\gamma}\)(b) Cp=R\(\frac{\gamma-1}{\gamma}\)(c) R=Cp\(\frac{\gamma+1}{\gamma}\)(d) Cp=R\(\frac{\gamma}{\gamma-1}\)I got this question in class test.Query is from Measurement of Airflow Characteristics in division Atmosphere and Air Data Measurement of Aircraft Performance

Answer»

Correct OPTION is (a) R=CP\(\frac{\gamma-1}{\gamma}\)

For explanation I would say: R=Cp\(\frac{\gamma-1}{\gamma}\) is the correct relationship between R and Cp where R= characteristic GAS constant, γ is the ratio of specific heat at constant pressure to that of specific heat at constant volume and Cp is the specific heat at constant pressure.
