Question: air with constant density of 12 kgm3 flows steadily past...

Question details

Qui24 3.30.2017 ME3022 Air with constant density of 1.2 kg/m3 flows, steadily, past an object in a pipe of 2-m diameter and exits as a free jet as shown in the following figure. The velocity upstream is uniform at 10 m/s. At the pipe exit the velocity is non-uniform as indicated. The shear stress along the pipe wall is negligible and pressure is uniform along the pipe. (a) Determine U2 (b)Determine the force that the air exerts on the subject. Air Wake 1-m dia 2-m-dia 4 02 12 m/s Exit 10 m/s
