- 81. ssm mmh A pressure difference of 1.8 × 10° Pa is needed to drive water (7 = 1.0 × 10-³ Pa · s) through a pipe whose radius is 5.1 × 10-³m. The volume flow rate of the water is 2.8 × 10-ª m³/s. What is the length of the pipe?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= roThe pressure drop along a length of artery is 103 Pa, the radius is 9.5 mm, and the flow is laminar. The average speed of the blood is 16.5 mm/s.Randomized Variables P = 103 Par = 9.5 mms = 16.5 mm/s a. What is the net force on the blood in this section of artery in N? b.

Tries 11/12 Previous Tries Post Discussion S Send FeedbackThe IV system shown below contains whole blood at a height of 0.857 m. Determine the gauge pressure (in psi) at the injection point [round your final answer to two decimal place]. 1 atm= 14.7 psi 1 atm = 1.013x105 Pa I atm = 760 mmHg h Density of whole blood = 1,060 kg/m³Suppose you measure a standing person’s blood pressure by placing the cuff on his leg 0.525 m below the heart. For this problem, assume that there is no loss of pressure due to resistance in the circulatory system (a reasonable assumption, since major arteries are large). The density of blood is 1.05×103 kg/m3 a. Calculate the systolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the top (and greater) number is the systolic pressure. b. Calculate the diastolic pressure you would observe, in units of mm Hgmm Hg, if the pressure at the heart was 120 over 80 mm Hg. Note that the bottom (smaller) number is the diastolic pressure.
- 11.23 Blood pressure is generally quoted in mmHg and is a gauge pressure. In this question we will convert this into SI units. Suppose that the systolic pressure of a particular patient is 120 mmHg and the diastolic pressure is 80 mmHg. Given that 760 mmHg is equivalent to 101.3 kPa, what is the systolic and diastolic blood pressure of this patient in SI units (Pa, or kPa)?When you hold your hands at your sides, you may have noticed that the veins sometimes bulge—the height difference between your heart and your hands produces increased pressure in the veins. The same thing happens in the arteries. Estimate the distance that your hands are below your heart. If the average arterial pressure at your heart is a typical 100 mm Hg, what is the average arterial pressure in your hands when they are held at your side?25,708 E 8. Water at a pressure of 4.70 atm at street level flows into an office building at a speed of 0.80 m/s through a pipe 5.00 cm in diameter. The pipes taper down to 2.00 cm in diameter by the top floor, 22.0 m above. Calculate the water pressure in such a pipe on the top floor. Pa 27 R DI C F V 96 5 T G tv 6.
