then the velocity of efflux is :

There are two identical small holes of area of cross section a on the opposite sides of a tank containing liquid of density ρ. The differences in height between the holes is h. The tank is resting ona smooth horizontal surface. The horizontal force which will have to be applied on the tank to keep [...]

The opening near the bottom of the vessel shown in the figure has an area A. A disc is held against the opening keep the liquid from running out. Let F1 be the net forces on the disc applied by liquid and air in this case. Now the disc is moved away from the opening [...]

A hole is made at the bottom of the tank filled with water (density 1000 kg/m^ 3 ), If the total pressure at the bottom ofthe tankis 3 atmosphere ( 1 atmosphere = 10 ^ 5 N/m ^2 ), then the velocity of efflux is : A hole is made at the bottom of the [...]

An iceberg is floating partially immersed in sea water. The density of sea water is 1.03gcm^−3 and that of ice is 0.92 g/cm^−3. The approximate percentage of total volume of iceberg above the level of sea water is A hole is made at the bottom of the tank filled with water (density 1000kg/m^3) If the [...]

A tube 1cm^2 in cross section is attached to the top of a vessel 1cm high and of cross section 100 cm^2. Water is poured into the system filling it to a depth of 100cm above the bottom of the vessel as shown in the figure. Take g=10ms^−2. Find the correct statement. A hole is [...]

A vessel contains oil (density =0.8gm/cm^3) over mercury (density =13.6g/cm^3). A homogeneous sphere floats with half its volume immersed in mercury and the other half in oil. The density of the material of the sphere in gm/cm^3 is A hole is made at the bottom of the tank filled with water (density 1000kg/m^3) If the [...]

An ideal fluid flows in the pipe as shown in the figure. The pressure in the fluid at the bottom p2​ is the same as it is at the top p1​. If the velocity of the top v1​= 2 m/s. Then the ratio of areas A1​. A2​ is A hole is made at the bottom [...]

The tension in a string holding a solid block below the surface of a liquid (Where ρliquid > ρblock) as shown in figure is T when the system is at rest. What will be the tension in the string if the system has an upward acceleration a? A hole is made at the bottom of [...]

A hole is made at the bottom of the tank filled with water (density 1000kg/m^3), If the total pressure at the bottom ofthe tank is 3 atmosphere ( 1 atmosphere = 10^5N/m^2 ), then the velocity of efflux is : A hole is made at the bottom of the tank filled with water (density 1000kg/m^3) [...]
