Question: A 1 ft high rectangular weir (weir 1) is installed in a 2 ft wide rectangular channel, and the head on the weir is observed

A 1 ft high rectangular weir (weir 1) is installed in a 2 ft wide rectangular channel, and the head on the weir is observed for a discharge of 10 cfs. Then the 1 ft weir is replaced by a 2 ft high rectangular weir (weir 2), and the head on the weir is observed for a discharge of 10 cfs. The ratio H₁/H₂ should be

(a) Equal to 1.00,

(b) Less than 1.00, or
