A $2\mathrm{.}4-$m$-$diameter tank is initially filled with water $3\mathrm{.}5$ m above the center of a sharp$-$edged $10-$cm$-$diameter orifice. The tank water surface is open to the atmosphere, and the orifice drains to the atmosphere. The loss coefficient is KL $=0\mathrm{.}5$ for a sharp$-$edged entrance. Neglecting the effect of the kinetic energy correction factor, calculate the initial velocity from the tank. $($Please provide an answer before moving on to the next part.$)$ The initial velocity from the tank is m$/$s$.$
