Water is discharged from a tank through a rectangular orifice of width 1.5 m and height 1.2 m. The water level in the tank is 3.5 m above the top edge of the orifice. If the coefficient of discharge of this orifice is 0.62, the discharge through the orifice in m³ s⁻¹ is [round off to 2 decimal places] (Take acceleration due to gravity, g = 9.81 m s⁻²)
