The velocity profile equation in Section 1 in a branched pipe stream is defined as follows: = , ( - 2 / ), = . Pipe diameters are displayed as D1 = 20 cm, D2 = 8cm and D3 = 4 cm, respectively. If the uniform velocity in Section 2 is u2 = 1 m / s, find the average velocity and direction of the current in Section 3.
