1. A width contraction in a horizontal channel is called a venturi flume. If the upstream channel width and depth are 0.6 and 0.3 m, respectively, and the flow rate is 0.1 m³/s, find the downstream critical depth, velocity, and width.

2. The width of a horizontal, rectangular channel expands smoothly from 6 ft to 7 ft. The upstream depth is 3 ft and the velocity is 5 ft/s. What is the downstream depth?
