Problem 59PE
We stated in Example 11.12 that a xylem tube is of radius 2.50×10−5 m . Verify that such a tube raises sap less than a meter by finding h for it, making the same assumptions that sap’s density is 1050 kg/m3 , its contact angle is zero, and its surface tension is the same as that of water at 20.0º C .
Example 11.12: Calculating Radius of a Capillary Tube: Capillary Action: Tree Sap
Can capillary action be solely responsible for sap rising in trees? To answer this question, calculate the radius of a capillary tube that would raise sap 100 m to the top of a giant redwood, assuming that sap’s density is 1050 kg/m3, its contact angle is zero, and its surface tension is the same as that of water at 20.0o C .

ANSWER:
Solution
Step 1 of 2
We need to find out the height “h” of the capillary rise in a xylem tube.
The height of liquid in a capillary action is given by the formula,
