PROBLEM SOLVING A weir is a dam that is built
across a river to regulate the flow of water. The flow
rate (in cubic feet per second) can be calculated
using the formula Q = 3.3676h32, where is the
length (in feet) of the bottom of the spillway and hi
is the depth (in feet) of the water on the spillway.
Determine the flow rate of a weir with a spillway that
is 20 feet long and has a water depth of 5 feet.
