Water flows out from a large tank of cross-sectional area 𝑨_𝒕 = 𝟏 m² through a small rounded orifice of cross-sectional area 𝑨_𝒐 = 𝟏 cm² , located at 𝒚 = 𝟎. Initially the water level, measured from 𝒚 = 𝟎, is 𝑯 = 𝟏 m. The acceleration due to gravity is 9.8 m/s² . Neglecting any losses, the time taken by water in the tank to reach a level of 𝒚 = 𝑯/𝟒 is _______________ seconds (round off to one decimal place).
