1. A channel conveys a discharge of 210 cfs at a velocity of 5.45 ft/s. Find the cross-sectional area of the channel.

2. A trapezoidal channel with bottom width of 4.00 feet and side slopes of 2 horizontal to 1 vertical carries a flow depth of 2.25 feet at an average velocity of 7.32 ft/s. What is the flow, Q, in the channel?
