During a marathon race, a runner's blood flow increases to 10.0 times her resting rate. Her blood's viscosity dropped to 95.0% of its normal value, and the blood pressure difference across the circulatory system has increased by 50.0%. By what factor bas be average radii of her blood vessels increased?
Angioplasty is a technique in which arteries partially blocked with plaque are dilated to increase blood flow. By what actor must the radius of an artery be increased in order to increase blood by a factor of 10?
A 75.0-kg floats in freshwater 3.00% of his volume above water when his are empty, and 5.00% of his volume above water when his lungs are full. Calculate the volume of air inhales—called his lung capacity—in liters. (b) Does lung volume seem reasonable?
Oxygen reaches the veinless cornea of the eye by diffusing through its tear layer, which is 0.500-mm thick. How long does it take the average oxygen molecule to do this?
Why does a bicycle pump feel warm as you inflate your tire?
The arterioles (small arteries) leading to organ constrict in order to decrease flow to the organ. To down organ, blood is reduced naturally to 1.00% of its original value. By what factor do the radii of the arterioles constrict?
Is there a limit to the height to which an entrainment device can raise a fluid? Explain your answer.
In an immersion measurement of a woman's density, she is found to have a mass of 62.0 kg in air an apparent mass of 0.0850 kg completely submerged with lungs empty. (a) What of water does she displace? (b) What is her volume? (c) Calculate her density. (d) If her lung capacity is 1.7S L, is she able to that without treading water with her lungs filled air?
Does atmospheric pressure add to the gas pressure in a rigid tank? In a toy balloon? When, in general, does atmospheric pressure not affect the total pressure in a fluid?
Doppler ultrasound can be used to measure the speed of blood in the body. If there is a constriction of an artery, where would you blood speed to be greatest: at or after the constriction? What are the two distinct causes of higher resistance the constriction?
A submarine is stranded on the bottom of the ocean with its hatch 25.0 m below surface. Calculate force needed to open the hatch from the inside, given it is circular and 0.450 m in diameter. Air pressure inside the submarine is 1.00 atm.
A frequency quoted rule of thumb aircraft design is that wings should produce about 1000 N of lift per square meter of wing. (The fact that a wing has a top and bottom surface does not double its area.) (a) At takeoff, an aircraft travels at 60.0 m/s, so that the air speed relative to the bottom of the wing is 60.0 m/s. Given be sea level density of air as 1.29kg/m3, how fast must it move over be upper surface to create the ideal lift? (b) How fast must air move over the upper surface at a cruising speed of 245 m/s and at an altitude where air density is one-fourth that at sea level? (Note that his not all of be aircraft's lift—some comes from be body of the plane, some from engine thrust, and so on. Furthermore, Bernoulli's principle gives approximate answer because flow over wing creates turbulence.)
