Water flows over a broad-crested weir that has a width of $4 \mathrm{~m}$ and a height of $P_{w}=1.5 \mathrm{~m}$. The free-surface well upstream of the weir is at a height of $0.5 \mathrm{~m}$ above the surface of the weir. Determine the flowrate in the channel and the minimum depth of the water above the weir block.
