The figure shows a liquid of given density flowing steadily in horizontal tube of varying cross - section. Cross sectional areas at A is $\displaystyle 1.5 \mathrm{~cm}^2$, and B is $\displaystyle 25 \mathrm{~mm}^2$, if the speed of liquid at $\displaystyle B$ is $\displaystyle 60 \mathrm{~cm} / \mathrm{s}$ then $\displaystyle \left(\mathrm{P}_{\mathrm{A}}-\mathrm{P}_{\mathrm{B}}\right)$ is : (Given $\displaystyle \mathrm{P}_{\mathrm{A}}$ and $\displaystyle \mathrm{P}_{\mathrm{B}}$ are liquid pressures at A and B points. density $\displaystyle \rho=1000 \mathrm{~kg} \mathrm{~m}^{-3}$ $\displaystyle A$ and $\displaystyle B$ are on the axis of tube
