- The leaves of a tree lose water to the atmosphere via the process of transpiration. A particular tree loses water at the rate of 4.0 x 10-8 m3/s. What mass of water is lost over the course of a single day? (Use 1000 kg/m3 for the density of water). 3.456 v kg This water is replenished by the upward flow of sap through vessels in the tree's trunk. If the trunk contains about 1800 vessels, each 0.1 mm in diameter, what is the speed of the sap flowing in the vessels? 0.243 x mm/shelp with this question.
