Q1: The value of y = cp/cv. at < 500°C for air & most common gases can be safely assumed to beA 0.8
B 1
C 1.4
D 1.8
ANS:C - 1.4 The value of cv/cp, also known as the specific heat ratio or adiabatic index, at temperatures below 500°C for air and most common gases can be safely assumed to be approximately 1.4. The specific heat ratio (cv/cp) is the ratio of the specific heat at constant pressure (cp) to the specific heat at constant volume (cv). For ideal diatomic gases like oxygen (O2) and nitrogen (N2), as well as for air (which is a mixture of oxygen and nitrogen), the specific heat ratio is approximately 1.4 over a wide range of temperatures and pressures. This value of 1.4 is a commonly accepted approximation for many engineering calculations involving gases, especially at temperatures and pressures within the range encountered in typical engineering applications. |
