The leaves of a tree lose water to the atmosphere via the process of transpiration. A particular tree loses water at the rate of 3.0 x 10-8 m/s. What mass of water is lost over the course of a single day? (Use 1000 kg/m3 for the density of water). kg This water is replenished by the upward flow of sap through vessels in the tree's trunk. If the trunk contains about 1900 vessels, each 0.1 mm in diameter, what is the speed of the sap flowing in the vessels? X mm/s

The average speed of blood in the aorta is 0.327 m/s, and the radius of the aorta is 1.00 cm. There are about 2.00 × 109capillaries with an average radius of 6.23 μm. What is the approximate average speed of the blood flow in the capillaries? ___mm/s

As blood is pumped from the heart, it moves through the ascending aorta and then down the descending thoracic aorta. The ascending aorta has an average cross-sectional area of approximately 7.07cm2, while the descending aorta has an average cross-sectional area of 4.52cm2. The heart pumps out blood at an average flow rate of 0.0800 L/s   . Determine the average speed of blood through the ascending aorta:___cm/s   Determine the average speed of blood through the descending aorta: ___cm/s

The blood flow rate through the aorta is measured to be 107.3 cm^3/s, and an adult is measured to have 5.02 L of blood. How long does it take for all of your blood to pass through the aorta?   If the adult's aorta has a diamter of 2.05 cm, what is the speed of blood as it flows through the aorta?

Balloon angioplasty is a technique to restore blood flow through coronary arteries that have been narrowed by the build-up of plaque. The surgeon threads a catheter into the coronary artery, then inflates a balloon that compresses the plaque against the wall of the artery. Suppose a diseased coronary artery has a diameter of 2.0 mm. To what diameter must it be expanded to increase the blood flow by a factor of 5.0 with no change in pressure?

At a given instant, the blood pressure in the heart is 1.1 x 104 Pa. If an artery in the brain is 0.38 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow. Number Type your answer here Units Choose your answer here
