2. At one section in an air distribution system, air at 101.3 MPa and 40 degrees F has an average velocity of 5 m/s and the duct is 300 mm x 300 mm square. At another section, the duct is round with a diameter of 450 mm, and the velocity is measured to be 4.6 m/s. Calculate the density of the air in the round section and the weight flow rate of air in N per hour. At 101.3 MPA and 40 degrees F, the density of air is 1.127 kg/m3 and the specific weight is 11.05 N/m3. 2.
