A tank with a square base of area `1.0m^(2)` is divided by a vertical parition in the middle. The bottom of the partition has a small hinged door of area `20cm^(2)`. The tank is filled with water and an acid (of relative density 1.7) in the other, both to a height of `4.0m`. Compute to force necessary the force nec cessary to keep the door closed.

A tank with a square base of area 2m^2 is divided into two compartments by a vertical partition in the middle. There is a small hinged door of face area 20 cm^2 at the bottom of the partition. Water is filled in one compartment and an of the partition. Water is filled in one compartment and an acid fo relvative density 1.5 in the other, both to a height of 4m. The force necassary to keep the door closed is (Take g = 10 m s^(-2))

The force does water exert on the base of a house tank of base area 1.5m^(2) when it is filled with water up to a height of 1 m is (g=10(m)/(s^(-2)))

Water flows into a large tank with flat bottom at the rate of 10^(-4) m^(3)s^(-1) . Water is also leaking out of a hole of area 1 cm^(2) at its bottom. If the height of the water in the tank remains steady, then this height is :

A rectangular tank of base area 100 m^(2) has a height of 2 m. Calculate the thrust at the bottom of the tank, if it is filled upto the brim with water of density 10^(3) kg m^(-3) .

The wooden plank of length 1 m and uniform cross section is hinged at one end to the bottom of a tank as shown in figure. The tank is filled with water up to a height of 0.5 m. The specific gravity of the plank is 0.5. Find the angle theta that the plank makes with the vertical in the equilibrium position. (Exclude the case theta=0 ) ,

The level of water in a tank is 5m high.A hole of area 1cm^2 is made in the bottom of the tank. The rate of leakage of water from the hole is (g=10ms^(-2)

A tank with vertical walls is monted so that its base is at height of 1.2 m above the horizotnal ground. The tank is filled with water to depth 2.8 m. A holw is punched in the side wall of the tank at a depth x m below the surface of water to have maximum range of the emerging stream. then the value of x in metre is

A large cylinderical tank of cross-sectional area 1m^(2) is filled with water . It has a small hole at a height of 1 m from the bottom. A movable piston of mass 5 kg is fitted on the top of the tank such that it can slide in the tank freely. A load of 45 kg is applied on the top of water by piston, as shown in figure. The value of v when piston is 7 m above the bottom is (g=10m//s^(2) ) (a). sqrt(120)m//s (b). 10m//s (c). 1m//s (d). 11m//s
