A hole is made at the bottom of the tank filled with water (density `=1000 kgm^(-3))`. If the total pressure at the bottom of the tank is three atmospheres (1 atmosphere `=10^(5) Nm^(-2))`, then the velocity of efflux is nearest to

There is a hole in the bottom of tank having water. If total pressure at bottom of the tank is 3 atm (1 atm = 10^5 Nm^(-2)) then the velocity of water flowing from the hole is

There is a small hole at the bottom of tank filled with water. If total pressure at the bottom is 3 atm(1 atm=10^(5)Nm^(-2)) , then find the velocity of water flowing from hole.

A water tank is 20 m deep . If the water barometer reads 10 m at the surface , then what is the pressure at the bottom of the tank in atmosphere ?

A tank 5 m high is half filled with water and then is filled to top with oil of density 0.85 g//cm^3 The pressure at the bottom of the tank, due to these liquids is

An object is placed at the bottom of a tank filled with liquid of refractive index 1.6. If the actual depth of the tank is 10 cm, what will be the apparent depth of the object?

If the pressure at half the depth of a tank is equal to 2/3 the pressure at the bottom of the tank, then the height of the water column in the tank is ("Atmospheric pressure "=10^5N//m^2 )

Calculate the total pressure at the bottom of a lake of depth 5.1 m (atm pressure =10^(5) P), density of water =10^(3)kg//m^(3),g=10m//s^(2)

A tank is filled with water of density 1 g cm^(-3) and oil of density 0.9 g cm^(-3) . The height of the water layer is 100 cm and of the oil layer is 400 cm. If g = 980 cm s^(-2) , then the velocity of efflux from an opening in the bottom of the tank is
