143376 A cylindrical tank with a large diameter is filled with water. Water drains out through a hole at a bottom of the tank. If the crosssectional area of the hole is $6 \mathrm{~cm}^{2}$ then the drainage rate (in $\mathrm{m}^{3} / \mathrm{s}$ ) when the depth of the water is $0.2 \mathrm{~m}$, is
