- Please help with this practice problem, I do not know where to start.As a person breathes, during the inhale part of the cycle air moves down the windpipe (bronchus) and through a constriction where the air speed doubles. If the air is traveling 41 cm/s before the constriction and we treat air as an incompressible fluid, determine the pressure drop in the constriction. Use the density of air as 1.29 kg/m3.When physicians diagnose arterial blockages, they quote the reduction in flow rate. If the flow rate in an artery has been reduced to 14.3% of its normal value by a blood clot and the average pressure difference has increased by 23.0%, by what factor has the clot reduced the radius, ro, of the artery? r= ro

Would the blood pressure reading change if it were taken at the proximal thigh? Why? Your answer should include a discussion on what factors determine the pressure of a fluid.Is it possible for a fluid in a tube to flow in the direction from low pressure to high pressure? If so, give an example. If not, why not?
- The flow of blood to your legs is 12 cm3/s. You begin exercising, and your arteries dilate so that their radius increases by 30%. The pressure difference remains unchanged. What is the new flow rate?Blood pressure in Argentinosaurus. If this long-necked, gigantic sauropod had a head height of 17.1 m and a heart height of 7.00 m, (a) what (hydrostatic) gauge pressure in its blood was required at the heart such that the blood pressure at the brain was 80.6 torr (just enough to perfuse the brain with blood)? Assume the blood had a density of 1.06 × 10^3 kg/m^3. (b) What was the blood pressure at the feet?Give your answers in torr or mm Hg.a stiff, 15-cm-long tube with an inner diameter of 3.5 mm is attached to a small hole in the side of a tall beaker. the tube sticks out horizontally. the beaker is filled with 20⁰c water to a level 50 cm above the hole, and it is continually topped off to it maintain that level. What is volume flow rate through the tube? The viscosity of water is 1.0×10^-3 Pa×s.
- A medical technician is trying to determine what percentage of a patient's artery is blocked by plaque. To do this, she measures the blood pressure just before the region of blockage and finds that it is P₁, while in the region of blockage it is P2. Furthermore, she knows that blood flowing through the normal artery just before the point of blockage is traveling at v₁, and the density of this patient's blood is p. The patient is laying down so there are no differential effects due to gravity. a. Symbolically, what is the ratio of the artery radius at the blockage, r2, to the ratio of the artery radius at the blockage, r₁? (find r₂/r₁) b. Find the numerical value of r2/r1. P₁ = 1.20x104 Pa, P₂=1.15×104 Pa, v₁ =30.0 cm/s, p = 1060 kg/m³.The blood speed in a normal segment of a horizontal artery is 0.14 m/s. An abnormal segment of the artery isnarrowed by an arteriosclerotic plaque down to one-fifth its normal cross-sectional area. What is the difference in bloodpressures between the normal and constricted segments of the artery? (The density of the blood is 1060 kg/m3)How tall must a water-filled manometer be to measure blood pressures as high as 300 mm Hg?
