PLEASE SOLVE USING METHODS DESCRIBED IN HINT $4.$ The tank shown discharges water in the atmosphere through an orifice. Find the outflow velocity when the water in the tank is maintained at an elevation of the $281\mathrm{.}7$ m $.$ The center of the orifice has an elevation of $\backslash (280\backslash$mathrm$\{$~m$\}.[\backslash$mathbf$\{10\}\backslash )]$

Hint: Apply Bernoulli's equation at the surface of the fluid in the tank $($pressure and velocity are zero$)$ and at a point just outside the outflow point $($pressure is zero as the outflow is in the atmosphere$).$
