¥If Pressure at Sea Level averages 1013 mb
and Temperature at Sea Level
averages 288 K, what is the
average Density at Sea Level?
¥Answer can be found using the Ideal Gas Law
¥ P(mb) = 2.87 « r(kg/m3) « T(K)
¥ r(kg/m3) = P(mb) / {2.87 « T(K)}
¥ r(kg/m3) = (1013 mb) / (2.87 « 288 K)
¥ r(kg/m3) = 1.23 kg/m3 È
2.00 lbs/yard3
