A 3 m wide and 2 m deep rectangular channel carries a discharge of 9
/s. If the kinematic viscosity of the water is 1.12 X
 ls, determine whether the flow is laminar or rurbulenr.

A trapezoidal channel with a 6 ft bed width, 3 ft water depth and 1: 1 side slope, carries a discharge of 250
/s. Determine whether the flow is supercritical or subcritical.
