Part 1

A cylindrical drum, open at the top, contains 30 litres of water. It drains out through a small opening at the bottom. 10 litres of water comes out in time t1, the next 10 litres in a further time t1 and the last 10 litres in a further time t3 Then, A cylindrical drum contains [...]

An engine pumps water continuously through a hose. Water leaves the hose with a velocity v and m is the mass per unit length of the water jet. What is the rate at which kinetic energy is imparted to water : an ideal liquid flows through the tube and pressure PA and PB at the [...]

There are two identical small holes on the opposite sides of a tank containing a liquid. The tank is open at the top. The difference in height between the two holes is h. As the liquid comes out of the two holes. The tank will experience a net horizontal force proportional to. an ideal liquid [...]

A liquid of density ρ comes out with a velocity v from a horizontal tube of area of cross-section A. The reaction force exerted by the liquid on the tube is F. Choose the incorrect option. A liquid of density ρ comes out with a velocity v from a horizontal tube of area of cross-section [...]

Water flows through two identical tubes A and B. A volume Vo of water passes through the tube A and 2 Vo through B in a given time. Choose the incorrect option. Water flows through two identical tubes A and B. A volume Vo of water passes through the tube A and 2 Vo through [...]

A liquid is kept in a cylindrical vessel which is being rotated about a vertical axis through the centre of the circular base. If the radius of the vessel is r and angular velocity of rotation is ω, then the difference in the heights of the liquid at the centre of the vessel and the [...]

In the figure, an ideal liquid flows through the tube, which is of uniform cross section. The liquid has velocities vA and vB, and pressure PA and PB at the points A and B respectively. an ideal liquid flows through the tube and pressure PA and PB at the points A and B respectively. In [...]

The tube shown in figure is of uniform cross-section. Liquid flows through it at a constant speed in the direction shown by the arrows. The liquid exerts on the tube The tube shown in figure is of uniform cross-section. Liquid flows through it at a constant speed in the direction shown by the arrows. The [...]

Water coming out of the mouth of a tap and falling vertically in stream line flow forms a tapering column. i.e., the area of cross-section of the liquid column decreases as it moves down which of the following is the most accurate explanation for this- the area of cross-section of the liquid column decreases as [...]

A large open tank has two holes in the wall. One is a square hole of side L at a depth y from the top and the other is a circular hole of radius R at a depth 4y from the top. When the tank is completely filled with water, the quantities of water flowing [...]
