In an equilateral triangular conduit, a certain increase in the flow race causes the maximum depth co increase by 1.5 times. Determine the percentage change in area, hydraulic depth, and discharge if the velocity of the flow is increased by 20%.

A trapezoidal channel has a side slope of 20° co the vertical and has a base width of 150 m. If the depth of flow is 6 m, determine the hydraulic radius, hydraulic depth, and section factor.
