Water is filled in a container up to height `3 m`. A small hole of area `'a'` is punched in the wall of the container at a height `52.5 cm` from the bottom. The cross sectional area of the container is `A`. If `a//A = 0.1`, then `v^(2)` is (where `v` is the velocity of water coming out of the hole)

A

`50`

B

`51`

C

`48`

D

`51.5`

Text Solution

Verified by Experts

The correct Answer is:
A
Apply continuity equation `A_(1)V_(1) = A_(2)V_(2)` and Bernuli theorum `(P_(0))/(rho) + (v^(2))/(2) + gh = "constant"` (at the top and at the hole)

Choose the correct option: Water is filled in a cylindrical container to a height of 3m . The ratio of the cross-sectional area of the orifice and the beaker is 0.1 . The square of the speed of the liquid coming out from the orifice is (g=10m//s^(2)) .

Water is filled in a uniform container of area of cross section A . A hole of cross section area a ( lt lt A) is made in the container at a height of 20 m above the base. Water streams out and hits a small block on surface at some distance from container. Block is moved on surface in such a way that stream always hits the block. The initial velocity of the block (in m//s ) is (Given (a)/(A)=(1)/(20) ). (Take g=10ms^(-2) )
