A liquid of density $\displaystyle 600 \mathrm{~kg} / \mathrm{m}^3$ flowing steadily in a tube of varying cross-section. The cross-section at a point $\displaystyle A$ is $\displaystyle 1.0 \mathrm{~cm}^2$ and that at $\displaystyle B$ is $\displaystyle 20 \mathrm{~mm}^2$. Both the points $\displaystyle A$ and $\displaystyle B$ are in same horizontal plane, the speed of the liquid at $\displaystyle A$ is $\displaystyle 10$ cm/s. The difference in pressures at $\displaystyle A$ and $\displaystyle B$ points is $\displaystyle \_\_\_\_$ Pa.
