143278 A liquid flows steadily through a cylindrical pipe having a radius $2 R$ at a point $A$ and radius $R$ at point $B$ farther along the flow direction. If the velocity at point $B$ is $4 \mathrm{v}$. what will be the velocity at point $A$ ?

143279 A large storage tank, open to the atmosphere at top and filled with water, develops a small hole in its side at a point $20.0 \mathrm{~m}$ below the water level. If the rate of flow from the hole is $3.08 \times$ $10^{-5} \mathrm{~m}^{3} / \mathrm{s}$, then the diameter of the hole is
