A sufficient atmospheric pressure required to push the water upto the top of tall plants must be

A

2 atm

B

6 atm

C

20 atm

D

All of the above

Text Solution

Verified by Experts

The correct Answer is:
C
Taller plants like Eucalyptus need higher pressure to raise the water up. While the value of root pressure ranges from 2.5 the atmosphere. A pressure of about 20atm is required to raise the water to tops of tall trees.

Figure shows a large closed cylindrical tank containing water. Initially, the air trapped above the water surface has a height h_(0) and pressure 2p_(0) where rh_(0) is the atmospheric pressure. There is a hole in the wall of the tank at a depth h_(1) below the top from which water comes out. A long vertical tube is connected as shown. Find the height of the water in the long tube above the top when the water stops coming out of the hole.
