10- Át the discharge of an air-conditioning duct, it is desirable to reduce the cross-sectional area of the duct, as shown in (Fig. P10). The cross-sectional area of the smaller duct is 0.02 m². At section 1 of the larger duct, the pressure, stagnation temperature and velocity are 150 kPa, 327 K and 71 m/s, respectively. If the flow throughout the duct is isentropic and discharge to an ambient pressure of 100 kPa, determine the mass flow rate [Answ. 6.66 kg/s]
