Air flows adiabatically in a converging duct, which is fed from a large reservoir where the temperature and the pressure are 305 K and 210 kPa, respectively. At the end of the duct,
where the cross-sectional area is 0.0025 the pressure and temperature are 172 kPa and
278 K, respectively, Determine the Mach number at the end of the duct and find the mass
flow rate.​
