(a) Find the average time (in s) required for an oxygen molecule to diffuse through a 0.2 mm thick tear layer on the cornea. (Assume the diffusion constant of oxygen through tears is 2e-9 m2/ 5. ) (b) How much time (in h) is required to diffuse 0.47 cm of oxygen to the cornea if its surface area is 1.03 cm-?. Question 6 0/1 pt 9 5 0 Details Hint (a) What is the pressure drop (in N/m ) due to the Bernoulli effect as water goes into a 2.7 cm diameter nozzle from a 9 cm diameter fire hose while carrying a flow of 32 L/s? (b) To what maximum height (in m) above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance
