A tank filled with fresh water has a hole in its bottom and water is flowing out of it. If the size of the hole is increased, then
A
the volume of water flowing out per second will decrease
B
the velocity of outflow of water remains unchanged
C
the volume of water flowing out per second remains zero

B
the velocity of outflow of water remains unchanged
b The velocity of outflow of water remains unchanged because it depends upon the height of water level and is independent of the size of the hole. The volume depends directly on the size of the hole.

A cylindrical tank of height $0.4\,m$ is open at the top and has a diameter $0.16\,m$ . Water is filled in it up to a height of $0.16\,m$ . How long it will take to empty the tank through a hole of radius $5 \times 10^{-3}\,m$ in its bottom .......... $\sec$
A square gate of size $1\,m \times 1\,m$ is hinged at its mid-point. A fluid of density $\rho$ fills the space to the left of the gate. The force F required to hold the gate stationary is
The rate of steady volume flow of water through a capillary tube of length $ 'l' $ and radius $ 'r' $ under a pressure difference of $P$ is $V$. This tube is connected with another tube of the same length but half the radius in series. Then the rate of steady volume flow through them is (The pressure difference across the combination is $ P$)
A solid sphere of specific gravity $27$ has a concentric spherical cavity and it just sinks in water. The ratio of cavity radius to that of outer radius of sphere is
A liquid is kept in a cylindrical vessel which rotated along its axis. The liquid rises at the sides. If the radius of the vessel is $0.05\,m$ and the speed of rotation is $2\,rev/s$ , The difference in the height of the liquid at the centre of the vessel and its sides will be .............. $\mathrm{cm}$ $(\pi ^2 = 10)$
A cylinder containing water up to a height of $25 cm$ has a hole of cross-section $\frac{1}{4}c{m^2}$ in its bottom. It is counterpoised in a balance. What is the initial change in the balancing weight when water begins to flow out
Water coming out of a horizontal tube at a speed ? strikes normally a vertically wall close to the mouth of the tube and falls down vertically after impact. When the speed of water is increased to $2v$ .
