Question

A gas, assumed ideal, flows isentropically from point 1,

where the velocity is negligible, the pressure is 200 kPa,

and the temperature is 300°C, to point 2, where the pressure

is 40 kPa. What is the Mach number Ma2 if the gas is

(a) air, (b) argon, or (c) CH_{4}? (d ) Can you tell, without

calculating, which gas will be the coldest at point 2?
