Extracted text: 1.39. Air flowing in a 4m x 6m rectangular duct has the following idealized velocity distribution: 1/5 V&,y) = 35 (1 – )* (1 - })"s, x\1/4 V (x,y) = 35 (1 - where x and y are distances in meters measured from the center of the duct and V is in m/s. Calculate the average velocity, the volume flow rate, and the kinetic energy correction factor. You may use either numerical calculation or analytic calculation. If you use numerical, the discretization error should be <>
