IIT JEE Questions And Answers :: Fluids In Motion: part1



IIT JEE : Fluids In Motion QUESTIONS AND ANSWERS :: part1 : 1 to 5

Following IIT JEE Entrance Multiple choice objective type questions and answers will help you in Maths, Physics and Chemistry 2014 examinations :

1.A liquid is poured into a vessel at rest with the hole in a wall closed by a valve. It is filled to a height H. The distance of hole from the top surface is h. With what horizontal acceleration should the vessel be moved so that the liquid does not come out when valve is opened ? (Given : l = length of base)

2gh
g
2gh/l
None of these

2.A liquid flows through two capillary tubes connected in series . Their lengths are L and 2L and radii r and 2r respectively. Then the pressure differences across the first and the second tube are in the ratio

8
4
2
1/8

3.A tube of length L and radius R is joined to another tube of length L / 3 and radius R / 2 . A fluid is flowing through this tube. If the pressure difference across the first tube is P, then the pressure difference across the second tube is

16P/3
4P/3
P
3P/16

4.A capillary tube is attached horizontally to a constant pressure head arrangement. If the radius of the capillary tube is increased by 10%, then the rate of flow of the liquid shall change nearly by

+ 10%
46%
- 10%
- 40%

5.Two large tanks, open at the top, contain two liquids. A small hole is made in the side of each tank at the same depth h below the surface of the liquid. One hole has twice the cross-section of the other. The ratio of the density of the liquids is [Mass flux of two liquids is same.]
