143275 Consider water flowing steadily in a pipe of varying cross sectional area and height as shown in figure. The area of cross section at $A$ $\& B$ are $20 \mathrm{~cm}^{2}$ and $40 \mathrm{~cm}^{2}$ respectively. The velocity of water at point $A$ is $2 \mathrm{~m} / \mathrm{s}$. The work done per unit volume as water moves from $A$ to $B$ in $\mathbf{J} / \mathbf{m}^{3}$ is
