Does anybody know the relationship between the air's viscosity and the pressure(0.1 to 10000 times of the atmosphere pressure)? Thanks a lot!!

1. Link the pressure to the temperature with some classical compressible fluids relations 2. Use the power or Sutherland's law which give the viscosity as a function of the temperature

thank you Buch!I am in the field of electrostatics,and I am working on eletrohydrodynamic flows.In my case the temperature is constant and only the pressure changes.
