4. You have a lung model whose airway flow is 90 liters/minute. The pressure at one end of the airway is 40 cm H2O, and the pressure at the other end of the airway is 5 cm H2O. What is the value for airway resistance in this model (watch your units!)?
Homework Answers
Airway resistance is the ratio of change in pressure to flow rate of air.
=Change in airway pressure/ flow f air
Airway flow =90 L/minute= 1.5 L/sec
Pressure at one end of airway= 40 Cm of H2O
Pressure at other end of airway= 5 Cm of H2O
Change in airway pressure= 40-5= 35 Cm of H2O
Airway resistance = Change in airway pressure / Flow of air
= 35/1.5= 23.3 Cm of H2O / sec

When you urinate, you increase pressure in your bladder to produce the flow. For an elephant, gravity does the work. An elephant urinates at a remarkable rate of 0.0060 m3 (a bit over a gallon and a half) per second. Assume that the urine exits 1.0 m below the bladder and passes through the urethra, which we can model as a tube of diameter 8.0 cm and length 1.2 m. Assume that urine has the same density as water, and...

Review Part A You have a lightweight spring whose unstretched length What is the magnitude of the charge (in nC) on each bead? Express your answer using two significant figures is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 2.4 g mass from it. This stretches the spring to a length of 5.3 cm. You then attach two small plastic beads to the opposite ends of the spring, lay the spring on...

You have a lightweight spring whose unstretched length is 4.0 cm. First, you attach one end of the spring to the ceiling and hang a 3.0 g mass from it. This stretches the spring to a length of 5.0 cm . You then attach two small plastic beads to the opposite ends of the spring, lay the spring on a frictionless table, and give each plastic bead the same charge. This stretches the spring to a length of 4.6 cm...

The purpose of this problem is to gain familiarity with stacks and queues. You have three jugs that can hold c1, c2, and c3 liters of water, respectively. Initially, jug 1 is full and the other two jugs are empty. You can repeat the following procedure any number of times: Choose two of the jugs and pour the contents of one into the other until either the first is empty or the second is full. Your goal is to end...
