Answer:
90ᵒ.
Explanation:
Channel is very important in engineering project for the drainage system. During the designing of the channel, its cross-section, roughness and bottom should be proper for better flow of water.
It is based on channel shape and bends slope to give a proper flow rate. For a uniform flow rate, the cross-section of the channel should be proper.
For the open channel, the angle should be right angle with equal sides for most economical and it should have wetted perimeter.
