The figure shows a liquid of given density flowing steadily in horizontal tube of varying cross - section. Cross sectional areas at $$\mathrm{A}$$ is $$1.5{\mathrm{cm}}^2$$, and $$\mathrm{B}$$ is $$25{\mathrm{mm}}^2$$, if the speed of liquid at $$\mathrm{B}$$ is $$60\mathrm{cm}/\mathrm{s}$$ then $$({\mathrm{P}}_{\mathrm{A}}-{\mathrm{P}}_{\mathrm{B}})$$ is :

(Given $${\mathrm{P}}_{\mathrm{A}}$$ and $${\mathrm{P}}_{\mathrm{B}}$$ are liquid pressures at $$\mathrm{A}$$ and $$\mathrm{B}$$% points.

density $$\rho =1000\mathrm{kg}{\mathrm{m}}^{-3}$$

$$\mathrm{A}$$ and $$\mathrm{B}$$ are on the axis of tube
