Answer

Explanation:

Step1: Apply Torricelli's Law

Torricelli's Law states that the velocity (v) of a fluid flowing out of an orifice is given by (v = \sqrt{2gh}), where (g) is the acceleration due to gravity ((g = 32.2\space ft/s^{2})) and (h) is the height of the fluid above the orifice.

Step2: Substitute the values

We are given (h = 10\space ft) and (g=32.2\space ft/s^{2}). Substitute these values into the formula: [ \begin{align*} v&=\sqrt{2\times32.2\times10}\ &=\sqrt{644}\ &\approx 25.4\space ft/s \end{align*} ]

Answer:

The discharge velocity of the liquid is approximately (25.4\space ft/s)
