Water flows out from a large tank of cross-sectional area $A_{t}=1 \text{ m}^{2}$ through a small rounded orifice of cross-sectional area $A_{o} = 1 \text{ cm}^2$, located at $y= 0$. Initially the water level, measured from $y = 0$, is $\text{H = 1 m}$. The acceleration due to gravity is $9.8 \text{ m/s}^{2}$.
Neglecting any losses, the time taken by water in the tank to reach a level of $\text{y = H/4}$ is __________________ seconds ($\textit{round off to one decimal places}$).
