Consider a converging duct flow. Conditions are given as below: (Station 1) - Air velocity (magnitude) = 175 m/s - Cross-sectional area = 1.8 m P, TP, and V are all constant in this plane PTP and V are all constant in this plane - Air pressure 1 atm (standard sea-level value) - Air density = 1.1 kg/m (Station 2) - Air temperature = 290 K Assuming "isentropic flow" and "calorically perfect ideal gas of air," calculate the followings: (a) Air flow Mach number at inlet (station 1) (b) Mass flow rate of air, in kg/s, through this duct (c) Air velocity, in m/s, and Mach number at outlet (station 2) (d) Air pressure (absolute), in Pa, at outlet (station 2) (e) Air density, in kg/m, at outlet (station 2) Station 2 Station 1
