Water flows through a vertical pipe of diameter 20 cm fitted with a venturi meter having a throat diameter of 10 cm. If the relationship between flow rate Q (in l/s) and manometric deflection y (in mm) of mercury is given such that a 10 mm deflection corresponds to 12.62 l/s, what is the approximate flow rate when the deflection is 10 mm?
