Question

A dam has two pipes in its wall. One is at depth of 5m from the surface of the water and the other is at a depth of 25 m
a. From which pipe will water gush out fastest and why?
b. Show how water will flow out from pipe A and pipe B.(Name the points and draw in your answer sheet)
Whoever will answer me the first I will mark brainliest.

Answer 1

Answer:

jejsjdjd the water of length of the water surface and a half hour of length of the year again when will you be able to get the latest flash player is required for video playback of the intended recipient you are mute button below to delete ho gaya hai jisase the water surface area and the water of 100 in the water is 1000 kilogram to kya hai to wo boli ki wo mere pass aa raha hu ki tarah hai to kya Naam hai ki aap se bhi Manga relations between the two of them are not the named addressee you should not be able and breadth of 300

Answer 2

Answer:

a) From pipe B water gush out fastest.

b) The range of water flowing from pipe B is more than the water flowing from pipe A.

Explanation:

Given,

Pipe A is at depth (d1) from the surface of the water is 5m.

Pipe B is at depth (d2) from the surface of the water is 25m.

To find,

a) From which pipe will water gush out fastest and why?

b) Show how water will flow out from pipe A and pipe B.

Calculation,

a) According to Torricelli's theorem the velocity of efflux(v) i.e. the velocity with which the liquid flows out of a hole is equal to √(2gh)

v = √(2gh)

i.e. v ∝ √h

Hence the more depth (h) the more velocity with which the water comes out.

Therefore, from pipe B water gush out fastest.

b) As water flowing from pipe B is more compared to the water flowing out of pipe B.

Therefore, the range of water flowing from pipe B is more than the water flowing from pipe A.
