Properties of Matter Part 2

The figure shows a liquid of given density flowing steadily in horizontal tube of varying cross - section. Cross sectional areas at A is 1.5cm2, and B is 25mm2, if the speed of liquid at B is 60‌cm∕ s then (PA−PB) is: (Given PA and PB are liquid pressures at A and B points)
Density ρ=1000‌kg‌m−3
A and B are on the axis of tube
