The area of cross-section of a large tank is `0.5 m^2`. It has a narrow opening near the bottom having area of cross-section `1cm^2`. A load of 25 kg is applied on the water at the top in the tank. Neglecting the speed of water in the tank, the velocity of the water, coming out of the opening at the time when the height of water level in the tank is 40 cm above the bottom, will be `cms^(-1)`. [Take `g=10 ms^(-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

Consider a water tank as shown in the figre. It's cross-sectional area is 0.4m^(2) . The tank has an opening B near the bottom whose cross-section area is 1 cm^2 . A load of 24kg is applied on the water at the top when the height of the water level is 40 cm above the bottom, the velocity of water combing out the opening B is v ms^(-1) . The value of v, to be nearest integer, is [Take value of g to be 10ms^(-2)]

Water flows out of a small hole in the wall of a large tank near its bottom. What is the speed of efflux of water when height of water level in the tank is 5.0 m ?

The level of water in a tank is 5 m high . A hole of the area 10 cm^2 is made in the bottom of the tank . The rate of leakage of water from the hole is

Water leaks out from an open tank through a hole of area 2mm^2 in the bottom. Suppose water is filled up to a height of 80 cm and the area of cross section of the tankis 0.4 m^2 . The pressure at the open surface and the hole are equal to the atmospheric pressure. Neglect the small velocity of the water near the open surface in the tank. a. Find the initial speed of water coming out of the hole. b. Findteh speed of water coming out when half of water has leaked out. c. Find the volume of water leaked out during a time interval dt after the height remained is h. Thus find the decrease in height dh in term of h and dt. d. From the result of part c. find the time required for half of the water to leak out.

The area of the base of a rectangular tank is 6500cm^(2) and the volume of water contained in it is 2.6 cubic metres.The depth of the water in the tank is
