The blood flow rate through the aorta is typically 99 cm3/s, and a typical adult has about 4.7 liters of blood. (a) How long does it take for all your blood to pass through the aorta? s (b) If your aorta has a diameter of 2.1 cm, what is the speed of blood as it flows through the aorta? cm/s
A blue whale’s heart pumps ∼20 liters of blood per second through its aorta, which has a diameter of 23 cm. A researcher wants to study the hydrodynamics of blood flow through the aorta. She decides to build a half-sized scale model of the aorta and flow water at room temperature through it. Calculate the flow speed in the actual aorta. What flow speed should she choose for the water in the model in order to correctly match the hydrodynamic...

Your heart does work to pump blood through your body. Each minute, 5.0 L of blood travels through your circulatory system. The pressure drops from 16 kPa as it exits the heart to approximately zero as it returns to the heart. We can calculate the work required to move a fluid volume V through a pressure difference with a formula very similar to the one you saw for work in gases. Part A What is the work done to pump...
The blood pressure at your heart is approximately 100 mm of Hg. As blood is pumped from the left ventricle of your heart, it flows through the aorta, a single large blood vessel with a diameter of about 2.5 cm. The speed of blood flow in the aorta is about 60 cm/s. Any change in pressure as blood flows in the aorta is due to the change in height: the vessel is large enough that viscous drag is not a...
Problem 7. (The speed of blood) The aorta (the main blood vessel coming out of the heart) has a radius of about 1.0 cm and the total cross section of the major arteries is about 20 cm². The density of blood is 1.05 g/cm3. A. Given that the velocity of blood pumping through the aorta is about 48 cm/s, what is the total current of the blood passing through the aorta (in grams of blood per second)? B. If all...
j4.Person A has a heart rate 90 heartbeats per min, a cardiac output of 6.8 L blood per minute and an end- diastolic volume of 170 mL blood. From this information, calculate the ciection fraction.

Problem 3: Blood is flowing through a hollow fiber that is 800 um in diameter and 30 cm in length. The average velocity of the blood within the hollow fiber is 25 cm sec1. The concentration of a drug is maintained at 10 mg L- along the inside surface of the hollow fiber. The diffusivity of the drug in blood is 4 x 10-6 cm2 sec 1. Given: Blood viscosity 3 cP, Blood density 1.02 g/cm3 a. Estimate the mass...
2a. Blood drawn from a healthy adult male has 24.0 mM НСО, and a PCO2 of 40.0 mm Hg. Calculate the pH of this sample. Use 0.0300 mmoVLemm Hg as Bunsen's solubility coefficient for CO2 and 6.10 for pK, of carbonic acid. 2b. Blood drawn from a patient with chronic pulmonary obstruction has the following parameters 30.0 mM HCO,, and a PCO2 of 60.0 mm Hg. Calculate the pH of this sample. Use the same constants as in question 2a....
3. The volume of blood plasma in an adult is 5.0 L, about 95% of which is water, and it has a density of 1.025 g/mL. The pressure at an underwater depth of 30.0 m is 4.1 atm (4.154325 bar). If a SCUBA diver descends to this depth, how many mg of N, (KH=6.0 x 10 mol/kg*bar) are dissolved in her blood? What percentage of N, comes out of the solution when the diver surfaces (at sea level)? Assume constant...
