Question:

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 20.0° C.

Strategy

The height to which a liquid will rise as a result of capillary action is given by h= 2y cos e pgr and every quantity is known except for r.
