Interpretation:
Themass flowrate and velocities of air flowing though trachea and both the primary bronchial tubes are to be calculated.
Concept introduction:
A flowchart is the complete representation of a process through boxes or other shapes which represents process units and arrows that represents the input and output of the process. The flowchart must be fully labelled to infer important data about the process involved.

- Follow the instructions of Problem 47 for the following set of bulbs.arrow_forwardExplain why the numbers of molecules are not identical in the left- and tight-hand bulbs shown in the center illustration of Figure 9.27.arrow_forward5-111 Diving, particularly SCUBA (Self-Contained Underwater Breathing Apparatus) diving, subjects the body to increased pressure. Each 10. m (approximately 33 ft) of water exerts an additional pressure of 1 atm on the body. (a) What is the pressure on the body at a depth of 100. ft? (b) The partial pressure of nitrogen gas in air at 1 atm is 593 mm Hg. Assuming a SCUBA diver breathes compressed air, what is the partial pressure of nitrogen entering the lungs from a breathing tank at a depth of 100. ft? (c) The partial pressure of oxygen gas in the air at 2 atm is 158 mm Hg. What is the partial pressure of oxygen in the air in the lungs at a depth of 100. ft? (d) Why is it absolutely essential to exhale vigorously in a rapid ascent from a depth of 100. ft?arrow_forward
- In an adult human, fully expanded lungs have a total lung capacity (TLC) of about 6 L. Some air remains after complete exhalation, and this volume is the functional residual capacity (FRC). A specific person has a known functional residual lung capacity (FRC) of 2.53 L and a total lung capacity (TLC) of 5.06 L. This person is in a room with an atmospheric pressure of 758.2 mmHg. Their internal temperature is 37.20 °C. How many moles of gas are exhaled with each breath? 1 4 7 0.298 moles 2 5 8 3 6 9 X сarrow_forwardTypically, when a person coughs, he or she first inhales about 2.50 L of air at 1.00 atm and 25 ∘C. The epiglottis and the vocal cords then shut, trapping the air in the lungs, where it is warmed to 37 ∘C and compressed to a volume of about 1.70 L by the action of the diaphragm and chest muscles. The sudden opening of the epiglottis and vocal cords releases this air explosively. Just prior to this release, what is the approximate pressure of the gas inside the lungs?arrow_forwardCan anybody help me? Thanks. The partial pressure of oxygen in the lungs is about 150 mm of Hg. (The partial pressure is the pressure of the oxygen alone, if all other gases were removed.) This corresponds to a concentration of 5.3×10^24 molecules per m^3. In the oxygen-depleted blood entering the pulmonary capillaries, the concentration is 1.4×10^24 molecules per m^3. The blood is separated from air in the alveoli of the lungs by a 1-μm -thick membrane. Assume the diffusion coefficient for oxygen in tissue is 2×10^−11m^2/s. 1.) What is the rate of transfer of oxygen to the blood through the 5×10^−9 surface area of one alveolus? Give your answer in molecules/s. Give your answer to 1 significant figure. 2.) What is the same rate of transfer in μmol/s? Give your answer to 1 significant figure.arrow_forward
- A 70kg man expends 480 kcal of energy per hour shoveling snow (note that kcalkcal is just a unit of energy). The oxidation of organic nutrients such as glucose during metabolism liberates approximately 3.36kcal of energy per gram of oxygen consumed. If air is 21% oxygen, what volume of air at STP is needed to produce enough energy for the man to clear snow from a 35 minutes of shoveling?arrow_forwarddemic Upgrading Chemistry 20 2. Magnesium was added to hydrochloric acid, HCI (aq), and produced 5.25 L of H₂ (g) at a temperature of 325 K and a pressure of 100 kPa. Mg(s) + 2 HCI (aq) → MgCl₂ (aq) + H₂(g) What mass of Mg was used in this single replacement reaction?arrow_forwardThe mw of ammonium silulphate is 132.14g/mol. How many grams of ammonium sulphate would be required to produce 25ml of 100millimolar ammonium sulphate?arrow_forward
- What is the volume needed for dH2Oarrow_forwardThree bulbs are connected by tubing, and the tubing is evacuated. The volume of the tubing is 34.0 mL. The first bulb has a volume of 84.0 mL and contains 3.68 atm of argon, the second bulb has a volume of 250 mL and contains 1.33 atm of neon, and the third bulb has a volume of 27.0 mL and contains 8.89 atm of hydrogen. If the stopcocks (valves) that isolate all three bulbs are opened, what is the final pressure of the whole system in atm? Answer: What is the total pressure if a container contains 57 torr of He gas, 196 torr of N2 gas, and 30 torr of Ar gas? Answer:arrow_forwardArterial blood pressure is traditionally measured in mm Hg. And the style pressure of 85 mm Hg it’s considered borderline between normal and high blood pressure convert this pressure to kPa units. ( 1atm =760 mm Hg= 101.33 kPa )arrow_forward
