Figure below shows a liquid being pushed out of the tube by a piston having area of cross section 2.0 `cm^2` . The area of cross section at the outlet is 10 `mm^2` . If the piston is pushed at a speed of 4 cm `s^(–1)` , the speed of outgoing fluid is ___ cm `s^(–1)`

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?

In the previous question, at the mouth of the tap the area of cross-section is 2.5 cm^2 and the speed of water in 3 m//s . The area of cross-section of the water column 80 cm below the tap is.

At the mount of the tap area of cross-section is 2.0cm^(2) and the speed of water is 3m//s . The area of cross-section of the water column 80 cm below the tap is (use g=10m//s^(2))

Water rises to a height of 20 mm in a capillary tube having cross sectiona area. If area of cross section of the tube is made A/4 ,then water will rise to a height of

How many litres of water flow out of a pipe having an area of cross-section of 5 cm^(2) in one minute, if the speed of water in the pipe is 30 cm/sec ?

How many litres of water flow out of a pipe having an area of cross-section of 5cm^(2) in one minute,if the speed of water in the pipe is 30cm/sec ?

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.

A cylindrical vessel contains a liquid of density rho up to height h . The liquid is closed by a piston of mass m and area of cross section A . There is a small hole at the bottom of the vessel. The speed v with which the liquid comes out of the hole is

A spray gun is shown in the figure where a piston pushes air out of a nozzle. A thin tube of uniform cross section is connected to the nozzle. The other end of the tube is in a small liquid container. As the piston pushes air through the nozzle, the liquid from the container rises into the nozzle and is sprayed out. For the spray gun shown, the radii of the piston and the nozzle are 20mm and 1mm respectively. The upper end of the container is open to the atmosphere. If the piston is pushed at a speed of 5mms^-1 , the air comes out of the nozzle with a speed of

The cylindrical tube of a spray pump has a cross-section of 8 cm^2 , one end of which has 40 fine holes each of area 10^-8 m^2 . If the liquid flows inside the tube with a speed of 0.15 m min^-1 , the speed with which the liquid is ejected through the holes is.
