By your numbers, the density of the air is increased by ~5%.
The uncertainty in the chosen wind speed will have much more effect than a slight variation in fluid density.
Additionally a 35F deg change in air temp will have more density effect than the sand suspended in the air.
For a project in Saudi-Arabia, I need to take into account the effect of sandstorms on a number of big aluminium silos.
The dust content of the sandstorm is defined as 0.065 kg/m3.
Is there any code or book that describes what to do in this case ?
I made the calculations as follows, but I do not know if this is the correct way.
Pressure coefficient silo : cw = 0.60
Density of the air : ro = 1.25 kg/m3
Dust content air : d = 0.065 kg/m3
Impact factor sand : Is = 2.0 (taken arbitrary)
Combined pressure coefficient air/sand :
Cc = cw . (ro + d . Is) / ro = 0.66
Thanks in advance for your ideas or commentary.
