An open vessel contains water upto height 50 cm in it. What is the velocity of efflux through an orifice at height 30 cm above the bottom level ? [Take g = 10 `m//s^(2)`]

A container filled with a liquid of density 4p as shown in the figure. The velocity efflux through orifice is ( rho is density of water and g = 10 ms^(-2) )

The velocity of efflux of a fluid through an orifice 15 cm below the fluid surface (which is open to the atmosphere) is [Take g = 10 m s^(-2) ]

A cylinder of height 20 m is completely filled with water. The velocity of efflux of water through a hole on the side wall of the cylinder near its bottom is (Take g=10 m s^(-2) )

A area of cross section of a large tank is 0.5m^2 . It has an opening near the bottom having area of cross section 1cm^2 . A load of 20 kg is applied on the water at the top. Find the velocity of the water coming out of the opening at the time when the height of water level is 50 cm above the bottom. Take g=10ms^-2

A body is thrown vertically upward from a point A 125 m above the ground. It goes up to a maximum height of 250 m above the ground and passes through A on its downward journey. The velocity of the body when it is at a height of 70 m above the ground is (g=10 m//s^(2))

An open vessel containing the liquid upto a height of 15 m. A small hole is made at height of 10 m from the base of the vessel then the initial velocity of efflux is (g = 10 m/ s^2 )

A tube 1 cm^2 in cross- section is attached to the top of a vessel 1 cm high and of cross - section 100 cm^2 Water is poured into the system filling it to a depth of 100 cm above the bottom of the vessel as shown in fig. Take g =10 ms^(-2) .
