`t/4`

B

2t

C

4t

D

`t/2`

Text Solution

Verified by Experts

The correct Answer is:
B
Time to empty a tank , `t=A/a sqrt((2H)/(g))`
or `tprop sqrtH rArr t_2//t_1 = 2`

There is a hole of area (1)/(25)cm^(2) in the bottom of a cylindrical vessel containing fluid up to height h . The liquid flows out in time t . If the liquid were filled in the vessel up to height 4h , then it would flow out in time

Two indentical cylinders have a hole of radius a (aleleR) at its bottom a ball of radius R is kept on the hole and water is filled in the cylinder sucj that there is no water leakage from bottom in case1 water is filled upto height h and in second case it is filled upto height 2h if F_(1) is net force by liquid on sphere in case1 and F_(2) is net force by liquid on sphere in case-2 then

consider a cylinder of radius R. At its bottom, there is a hole of radius r. the cylinder is filled upto the height h and the hole is opened. If t is the time in which the cylinder is emptied, then find the relation between t and h.

A cylindrical vessel of height 500mm has an orifice (small hole) at its bottom. The orifice is initially closed and water is filled in it up to height H. Now the top is completely sealed with a cap and the orifice at the bottom is opened. Some water comes out from the orifice and the water level in the vessel becomes steady with height of water column being 200mm. Find the fall in height(in mm) of water level due to opening of the orifice. [Take atmospheric pressure =1.0xx10^5N//m^2 , density of water=1000kg//m^3 and g=10m//s^2 . Neglect any effect of surface tension.]

A cylindrical vessel is filled with water upto a height of 1m. The cross-sectional area of the orifice at the bottom is (1//400) that of the vessel. (a) What is the tiome required to empty the tank through the orifice at the bottom? (b) What is the time required for the same amount of water to flow out if the water level in tank is maintained always at a height of 1m from orifice?
