A mixture of oxygen and nitrogen gas is contained in a pipe at 298 K and 1 atm total pressure which is constant throughout At one end of the pipe the partial pressure pA1 of oxygen is 0 70 atm and at the other end 0 8 m pA2 = 0 2 atm Calculate the molar and mass flux of oxygen at steady state if DAB of the mixture is 0 206 cm 2/s
Moving slowly through the smelting and converting zones matte is lanced with air (or oxygen-enriched air) causing con- version to white metal and then to copper If oxygen is not used lance air and combustion air preheaters are required as are a larger furnace boiler and electrostatic precipitator (ESP) In the converting zone the hearth
By transferring more air and air higher in oxygen content during each breath birds achieve a more efficient rate of gas exchange than do mammalsThe air-sac system is an inconspicuous but integral part of the avian respiratory systemAir sacs are thin-walled

Volumes of flue gas produced can often be reduced by using oxygen or oxygen enriched air for combustion instead of atmospheric air which has a larger volume for every oxygen unit For example in copper smelting the Inco process and the Noranda process use oxygen or oxygen enriched air for combustion A smaller volume of off-gas usually results
The case with 40 percent by volume N 2 leaves a residual oxygen content of about 13 percent by volume which is about double to triple the content usually experienced at the intermediate absorber Thus it is to be expected that the UEL in this case will be below the tabled figures
