A channel of width 450 mm branches into sub-channels having width 300 mm and 200 mm as shown in figure. if the volumetric flow rate (taking unit depth) of an incompressible flow through the main channel is 0.9 m3/s and the velocity in the sub-channel of width 200 mm is 3 m/s, the velocity in the sub-channel of width 300 mm is _________
Assume both inlet and outlet to be at the same elevation
