Question

The figure shows a liquid of given density flowing steadily in horizontal tube of varying cross - section. Cross sectional areas at A is 1.5 cm², and B is is 25 mm², if the speed of liquid at B is 60 cm/s then $(P_A-P_B)$ is:
(Given $P_A$ and $P_B$ are liquid pressures at A and B points.
density $ρ = 1000 \space kg \space m^{-3}$
A and B are on the axis of tube)
