1. Water flows in symmetrical trapezoidal channel lined with asphalt has a base width of 4.8 m and side slope of 3 horizontal to 1 vertical. It has a depth of flow of 1.36 m the channel drops 01 m vertically every 100 m. Using n = 0.015 A) Compute for the velocity of flow B) Compute for the critical velocity C) Compute for the discharge of the most efficient section if 0 = 30°, b=4.8m
