Express the critical depth and critical velocity in terms of the specific energy for a triangular channel which has equal side slopes of n horizontal to 1 vertical.

A very wide section has a flow per unit width of 32
. Calculate the critical depth and the corresponding specific energy. If chis specific energy is the minimum energy for another channel with a 90° triangular section, calculate the critical depth and the critical discharge for the triangular section.
