(b)(i))The Earth has an atmosphere which consist of a mixture of air. The average density of air is 1.225 kg m3 and the atmospheric pressure is 1.0 x 105 P a at the Earth's surface.Calculate the height of the atmosphere.p = hpg1.0*10^(-1)=11(1.225)(0.81) h = 8321 m8321...
air densityreconstructionThe possibility of reconstructing the spatial distribution of average air density in a supersonic jet from results of laser transillumination is considered. It is shown that the reconstruction procedure for axisymmetric flows can be performed based on Abel transforms by results of...
BEIJING, Nov. 14 (Xinhua) -- Beijing's average PM2.5 density decreased in the first ten months of this year, authorities said Monday. Beijing's average density of hazardous fine particulate matter from January to October was 64 micrograms per cubic meter, a year-on-year decrease of 8.6 per...
The model calculates subterranean transport and storage of heat as a function of depth-varying thermal conductivity and bulk density of the lunar regolith. We chose a validated physics-based model to verify Equations (10) and (11a) over the actual Diviner measurements, because the latter do not...
