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

When measuring blood pressure, why is the cuff placed at the level of the heart? 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.
Which is true about the volume flow rate and speed of the fluid flowing in the tube on the right?

A pipe with a cross section area of 0.5 m^2 has a fluid flowing through it at a speed of 2m/s. If the pipe’s cross section area is reduced to 0.25 m^2, what is the speed of the fluid in the reduced section?
Question 8 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 fınds that it is 1.20 × 104 Pa, while in the region of the 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 traveling at 30.0 cm/s, and the specific gravity of this patient blood is 1.06. What percentage of the cross-sectional area of the patient's artery is blocked by the plaque? (NO NEED TO PUT PERCENT SYMBOL).
Which is not a reason why the blood pressure meter cuff is placed in the left arm? Choices: Because it has the same pressure as the heart since it belongs to the same horizontal Because it has the brachial artery which pulse is comparable to the heart Because it is nearest to the heart compared to other parts Because it is the most convenient part of the patient
