Air expands isentropically from 2.2 MPa and 95°C to 0.4 MPa. Calculate the ratio of the initial to final speed of sound. The properties of air are R=0.287 kJ/kg-K and k=1.4. The specific heat ratio k varies with temperature, but in our case this change is very small and can be disregarded. The ratio of the initial to final speed of sound is
