For the 50 -ft-wide rectangular open channel section shown below, determine the depth of flow and the velocity at section 2 using (a) the energy equation and (b) the momentum equation. Disregard the energy losses. Bed slope for the channel is $$1:1000(\mathrm{V}:\mathrm{H})$$. Water density is $$1.938$$ slugs $$/{\mathrm{ft}}^3$$.
