Whole blood has a surface tension of 0.058 N/m and a density of 1050 kg/m3. To what height can whole blood rise in a capillary blood vessel that has a radius of 2.0 x 10-6 m if the contact angle is zero?

At a given instant, the blood pressure in the heart is 1.7 x 104 Pa. If an artery in the brain is 0.46 m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.

A cylindrical storage tank has a cross sectional area A1=1.5 m². The tank is set up vertically on the ground and filled with V=7.5 m³ of water. There is a valve at the bottom of the tank with an internal cross sectional area of 1.5 cm². What fraction of the total volume will be drained in the first 50 minutes after the valve is opened?

A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measured the blood pressure just before the region of blockage and finds that it is 1.20 × 104 Pa, while in the region of blockage it is 1.15 x 104 Pa. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is travelling at 30.0 cm/s. What percentage of the cross-sectional area of the patient's artery is blocked by the plaque?

There are two carotid arteries that feed blood to the brain, one on each side of the neck and head. One patient’s carotid arteries are each 11.2 cm long and have an inside diameter of 5.2 mm. Near the middle of the left artery, however, is a 2.0-cmlong stenosis, a section of the artery with a smaller diameter of 3.4 mm. For the same blood flow rate, what is the ratio of thepressure drop along the patient’s left carotid artery to the drop along his right artery?

At a given instant, the blood pressure in the heart is 1.4 x 10^4 Pa. If an artery in the brain is 0.49m above the heart, what is the pressure in the artery? Ignore any pressure changes due to blood flow.

Calculate the pressure drop per centimeters length of the aorta when the blood flow rate is 25 L/min. The radius of the aorta is about 1 cm, and the coefficient of viscosity of blood is 4 x 10-2 poise. Answer: ▵P= 3.19 x 10-2 torr.

The blood pressure in someone's heart is 1.70 104 Pa at a certain instant. An artery in the brain is 0.53 m above the heart. What is the pressure in the artery? The density of blood is 1060 kg/m^3.

A glucose solution being administered with an IV has a flow rate of 3.95 cm3/min Q = 3.95 cm3/min a. What will the new flow rate be if the glucose is replaced by whole blood having the same density but a viscosity 2.50 times that of the glucose in cm3/min? All other factors remain constant.

alculate the mass flow rate (in grams per second) of blood (?=1.0ρ=1.0 g/cm33) in an aorta with a cross-sectional area of 2.0 cm22 if the flow speed is 31.6 cm/s.   Assume that the aorta branches from a large number of capillaries with a combined cross-sectional area of 3.0×1033.0×103 cm22. What is the flow speed in the capillaries?
