Question: A woman's systolic blood pressure when resting is 160 mm Hg. Convert this pressure to: (a) pascals (Pa) (b) pounds per square inch (lb/in²) (c) atmospheres (atm) (d) torr Answer: (a) 21331.52 Pa (b) 3.093888 lb/in² (c) 0.21052624 atm (d) 160 torr

Step by step solution

01

Convert mm Hg to Pa

Identify the conversion factor between mm Hg and Pa: 1 mm Hg ≈ 133.322 Pa Now, multiply the woman's systolic blood pressure in mm Hg by this conversion factor to convert it to pascals (Pa). 160 mm Hg × (133.322 Pa / 1 mm Hg) ≈ 21331.52 Pa
02

Convert mm Hg to lb/in²

Identify the conversion factor between mm Hg and lb/in² (psi): 1 mm Hg ≈ 0.0193368 lb/in² Now, multiply the woman's blood pressure in mm Hg by this conversion factor to convert it to pounds per square inch (lb/in²). 160 mm Hg × (0.0193368 lb/in² / 1 mm Hg) ≈ 3.093888 lb/in²
03

Convert mm Hg to atm

Identify the conversion factor between mm Hg and atm: 1 mm Hg ≈ 0.001315789 atm Now, multiply the woman's systolic blood pressure in mm Hg by this conversion factor to convert it to atmospheres (atm). 160 mm Hg × (0.001315789 atm / 1 mm Hg) ≈ 0.21052624 atm
04

Convert mm Hg to torr

There is a direct relationship between mm Hg and torr. 1 mm Hg = 1 torr So, the woman's systolic blood pressure in torr is the same as in mm Hg. 160 mm Hg = 160 torr In summary, the woman's systolic blood pressure when resting is: (a) 21331.52 Pa (b) 3.093888 lb/in² (c) 0.21052624 atm (d) 160 torr

Most popular questions from this chapter

While vacationing at the Outer Banks of North Carolina, you find an old coin that looks like it is made of gold. You know there were many shipwrecks here, so you take the coin home to check the possibility of it being gold. You suspend the coin from a spring scale and find that it has a weight in air of 1.75 oz (mass \(=49.7 \mathrm{g}\) ). You then let the coin hang submerged in a glass of water and find that the scale reads \(1.66 \mathrm{oz}\) (mass $=47.1 \mathrm{g}$ ). Should you get excited about the possibility that this coin might really be gold?
At the surface of a freshwater lake the pressure is \(105 \mathrm{kPa} .\) (a) What is the pressure increase in going \(35.0 \mathrm{m}\) below the surface? (b) What is the approximate pressure decrease in going \(35 \mathrm{m}\) above the surface? Air at \(20^{\circ} \mathrm{C}\) has density of $1.20 \mathrm{kg} / \mathrm{m}^{3} .$
What is the average pressure on the soles of the feet of a standing 90.0 -kg person due to the contact force with the floor? Each foot has a surface area of \(0.020 \mathrm{m}^{2}\).
A sphere of radius \(1.0 \mathrm{cm}\) is dropped into a glass cylinder filled with a viscous liquid. The mass of the sphere is \(12.0 \mathrm{g}\) and the density of the liquid is \(1200 \mathrm{kg} / \mathrm{m}^{3} .\) The sphere reaches a terminal speed of \(0.15 \mathrm{m} / \mathrm{s} .\) What is the viscosity of the liquid?
(a) What is the pressure difference required to make blood flow through an artery of inner radius \(2.0 \mathrm{mm}\) and length \(0.20 \mathrm{m}\) at a speed of \(6.0 \mathrm{cm} / \mathrm{s} ?\) (b) What is the pressure difference required to make blood flow at \(0.60 \mathrm{mm} / \mathrm{s}\) through a capillary of radius \(3.0 \mu \mathrm{m}\) and length \(1.0 \mathrm{mm} ?\) (c) Compare both answers to your average blood pressure, about 100 torr.
