Figure shows a liquid of densith `1200kgm^-3` flowing steadily in a tube of varying cross section. The cross section at a point A is `1.0cm^2` and that at B is `20mm^2`, the points A and B are in the same horizontal plane.The speed of the liquid at A is 10 `cms^-1`. Calculate the difference in pressure at A and B.
