The flow rate can be calculated using the formula for flow over a weir: Q = (2/3) * b * sqrt(2g) * (h1^(3/2) - h2^(3/2)), where b is the width (1 m), g is the acceleration due to gravity (9.81 m/s²), h1 is the upstream depth (2.00 m), and h2 is the downstream depth (0.50 m). Plugging in these values gives approximately 2.80 m³/s/m.
