1.A 17ft long kayak moves with a speed of 5 ft/s. Would a boundary layer type flow be developed along the sides of the boat? Explain. The water temperature can be assumed to be 60 degrees F.

2.The Einsten's equation is dimensionally homogeneous. determine the dimensions of E if V is velocity and m mass.

3.A rectangular channel (n=0.015) is 6.0 m wide with a discharge rate of 60 cms and a longitudinal slope of 0.01. What is the expected depth of flow in the channel?

4.A gunite concrete trapezoidal channel with 1:2 side slopes, as ilustrated below, conveys 60 m3/s on a slope of 0.0005. Compute the depth of flow.
