what could cause turbulent air flow through the respiratory tract?
Homework Answers
Turbulent flow is when the air is not flowing in parallel layers, but direction, velocity and pressure within the flow of air become chaotic. If airflow becomes turbulent, the pressure difference required to maintain airflow will need to be increased, which in turn would increase turbulence and therefore resistance.
This means that turbulence leads to a need for a much greater difference in pressure to move the air. In physiological terms this means the pressure difference between the outside air and within the lungs would need to be increased, so the intercostal muscles and diaphragm would need to work harder to expand and contract the lungs.

Which of the following statements are true (could be multiple) for internal flow through a pipe? In laminar flow, the Nusselt is higher for constant wall temperature compared to that for constant heat flux. In turbulent flow, the Nusselt number is higher at the pipe exit than at the pipe entrance In laminar flow, the Nusselt number is lower at the pipe exit than at the pipe entrance In laminar fully developed flow, the Nusselt number is independent of Reynolds...

#2 Turbulent Flow in Pipes Water (p-1000 kg/m3, щ-0.001 N. s/m2) flows through a 0.1 m pipe at 0.1 m/s. . Verify that the flow is turbulent by showing Re >4000 The profile of the mean velocity is given by 4 4 and v 0 in units of m/s. (Here u refers to the axial flow velocity and v refers to the radial velocity.) We are also given 0.0004, v0.0001, and vv 0.0004 in units of m'/s2. Compute the turbulent...

Choose the correct Answer. 1. What is the function of goblet cells in the respiratory tract? These alveolar cells are thin and therefore function in gas transport. These alveolar cells function in the production of surfactant production. These cells are macrophages and therefore function in immune response/defense. These ciliated cells are found in the bronchi and function to move mucus up the respiratory tract. These cells are found in trachea and bronchi, and function in the production of mucus. 2....

Consider the turbulent flow of air, density 1.2 kg/m3 and kinematic viscosity 1.5x10-5m2/s, through a channel bounded by two infinitely wide parallel plates 0.2 m apart. At a certain downstream location where fully-developed conditions apply, the wall shear stress is measured to be 0.027 N/m2. a. Determine the streamwise mean velocities at locations 0.25 mm and 1 cm from the wall. b. At which of these two locations do you expect to find the larger Reynolds shear stress.
