Given a trapezoidal channel with a bottom width of 5 m, side slopes of 2:1, and a flow depth of 3 m, calculate the hydraulic radius and determine if the flow is uniform.
💡 Hint: Make sure to correctly apply the trapezoidal area formula.
Analyze how changing the channel slope from 1% to 2% affects the velocity distribution at a depth of 2 meters.
💡 Hint: Consider how gravitational forces influence flow characteristics in this scenario.
