Collisions with a Wall
Calculate the number of collisions per square meter per second of air molecules with a wall at a pressure of 1 atm and 23 deg C.
Assume air is 21%O2 and 79%Nitrogen
<= this gets the concentration of molecules
<= From the 1 dimensional probability function x the concentration of molecules (n).
<=Answer
-----------------------------------------------------------
So How many collisions would occur with a spot (hole) on the wall that was 100 microns in diameter?
<= Answer = Less
