Figure shows a liquid being pushed out of a tube by pressing a piston. The area of cross section of the piston is 1.0 cm^2 and that of the tube at the outlet is `20 mm^2`. If the piston is pushed at a speed of `2cms^-1`. What is the speed of the outgoing liquid?

A piston of cross sectional area 2cm^2 pushes the liquid out of a tube whose area at the outlet is 40mm^2 . The piston is pushed at a rate of 2cm//s . Determine the speed at which the fluid leaves the tube.

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.
