A water-resistant sheet used for water-proofing applications is formed from an impermeable polymeric material. The microstructure of the sheet is engineered to provide open pores of diameter D = 10 µm that extend through the entire thickness of the L = 100-µm-thick sheet. The pore diameter is large enough to allow water vapor to be transferred through the pore, but is sufficiently small to prohibit liquid water from penetrating through the sheet. a) Determine the rate (mol/s) at which water vapor is transmitted through a single pore when saturated liquid exists on the top of the sheet and moist air at a relative humidity of 50% exists on the bottom side of the sheet at temperature of T = 298 K and a pressure of P = 1 atm. At 298 K, the diffusion coefficient for water vapor through air is, .DAB = 0.26 x 10-4 m2/s.

b) Determine the rate (mol/s) at which water vapor is transmitted through a single pore in the absence of advection. Comment on the results.

c) Investigate the sensitivity of the transfer rate, both including and neglecting advection, to temperature. Consider a temperature range from 300 K to 360 K. Comment on the results.

Quickly! brainliest if two people answer! 1. the blood has red blood cells, white blood cells and platelets. red blood cells carry oxygen to other cells in the body. cells need oxygen to live. white blood cells destroy certain germs. they protect our bodies from disease. which question is answered in this paragraph? (a) what is the role of blood vessels? (b) what type of cells are attached to bones? (c) what type of blood cell to clot your blood? (d) what are the different types of blood cells? 2. which sentence from the section "stem cells" best explains the role of stem cells? (a) when one kind of cell stops working, stem cells can . (b) they can turn into that cell and take its place. (c) scientists are studying new ways to use stem cells. (d) these cells can people heal faster. 3. read the selection from the section "nerve cells." nerve cells send messages to the rest of our bodies. these messages move between the brain, spinal cord and various organs. nerve cells are also called neurons. fill in the blank. a "neuron" is a (a) cell that moves information from the brain to other parts of the body (b) stem cell that has both an axon and a dendrite (c) cell that controls the fingers of a body (d) cell that makes up the spinal cord 4. some muscles in our body move without us telling them to. these are called involuntary muscles. some examples are the cardiac muscle cells inside the heart. these cells the heart relax and fill with blood. what is the best definition of "involuntary" based on the context clues? (a) something that happens on its own (b) trying hard to do something (c) something moving back and forth (d) easily moved
