Question: If the approach velocity is not too high, a hump in the bottom of a water channel causes a dip Δh in the water level,

If the approach velocity is not too high, a hump in the bottom of a water channel causes a dip Δh in the water level, which can serve as a flow measurement. If, as shown in Fig P3.175, Δh = 10 cm when the bump is 30 cm high, what is the volume flow Q1 per unit width, assuming no losses? In general, is Δh proportional to Q1? Fig P3.175
