The culvert carries water and is at a downward slope $S_0$. Find the depth $y$ that will produce the maximum volumetric flow.

The drainage pipe is made of finished concrete and is sloped downward at $0.002$. Calculate the volumetric flow from the pipe if the center depth is $y=1 \mathrm{~m}$. Take $n=0.012$.

The channel has a triangular cross section and is flowing full. Calculate the volumetric flow of water if the sides are made of wood and the downward slope is $0.002$. Take $n=0.012$.

The drainage pipe is made of unfinished concrete and is sloped downward a t $0.0025$. Find the volumetric flow from the pipe if the center depth is $y=3\ \mathrm{ft}$.

The channel is made of finished concrete and has the cross section shown. If the downward slope is $0.0006$, find the flow of water through the channel when $y=5\ \mathrm{ft}$. Take $n=0.012$

The channel has a triangular cross section and is flowing full of water. Find the volumetric flow if the sides are made of wood and the downward slope is $0.002$.
