At steady state, air at 200 kPa, 325 K, and mass flow rate of 1.0 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. The inlet cross-sectional area is 6 cm2. At the duct exit, the pressure of the air is 100 kPa and the velocity is 300 m/s. Neglecting potential energy effects and modeling air as an ideal gas, determine a. the velocity of the air at the inlet, in m/s. b. the temperature of the...
