In this problem you are going to use your knowledge of drag forces to estimate how long a COVID-19 infected droplet will remain in the air when exhaled. Treat the droplet as a sphere of water with a 5 μm radius. Use the size and density of water to determine the mass of the sphere. Find the terminal velocity of the droplet and, using a reasonable height, approximate the time the droplet will remain in the air.

The volume of air we breathe in is about 10% of lung capacity perbreath. If the level of PM2.5 is constant at 40 μg/m3 over the wholeyear, how many grams of dust would you inhale in total in one year,assuming that the dust particles in every breath are all collected inyour lung?
The volume of sample loaded (Vini) to a capillary by hydrodynamic injection can be calculated using the Hagen-Poiseuille equation, 4 Vinj = = [7 d tinj AP(1287 L) where AP = pressure difference across the capillary, d = capillary inside diameter, tini = injection time, n = buffer viscosity, L = total capillary length. What volume of sample in nanoliter (nL) would be applied to a 50 um ID x 20 cm long capillary if a pressure of 0.5 psi is applied for 1 s to a solution with a viscosity of 0.01 poise (P)?

In a person infected with measles, the virus level N (measured in number of infected cells per ml of blood plasma) reaches a peak density at about t 12 days (when a rash appears) and then decreases fairly rapidly as a result of immune response. The area under the graph of N(t), the t-axis, and the lines t = 0 to t = 12, (as shown in the figure) is equal to the total amount of infection needed to develop symptoms (measured in density of infected cells x time). N= f) 1000- 12 21 The function has been modeled by the function (t) = -t(t - 21)(t + 1). Use this model with six subintervals and their midpoints to estimate the total amount of infection (in (infected cells/mL) - day) needed to develop symptoms of measles.t (infected cells/mL) day Need Help?

If it is known that each plot of the inspection screen on the drawing is 1 mm in size. Then a drop oil takes 3 seconds to pass 1 plot. The density of the oil is known, the viscosity of air, and the density of air respectively are 920 kg/m3; 1.85×10-5 Ns/m2; and 1,184 kg/m3. Determine the radius of the oil drop!
