An earth canal containing weeds and grass has a bottom width of 15 ft. and side slopes of 2 horizontal to l vertical. The depth of water is 4 ft. and the slope is 2.75 ft. per mile. It is desired to change the section to a semi-circular concrete-lined channel having a slope of 1.5 ft. in 1,000 ft. Determine the radius of the semi-circular channel in ft if it flows full. Use n = 0.035 for t

Question
An earth canal containing weeds and grass has a bottom width of 15 ft. and side slopes of 2 horizontal to l vertical. The depth of water is 4 ft. and the slope is 2.75 ft. per mile. It is desired to change the section to a semi-circular concrete-lined channel having a slope of 1.5 ft. in 1,000 ft. Determine the radius of the semi-circular channel in ft if it flows full. Use n = 0.035 for the earth canal and 0.012 for the concrete-lined channel.
