Question

Environmental Engineering

The air quality standard for ozone (O3) is 80 ppbv.

• Express that standard in micrograms per cubic meter at 1 atm pressure and 25oC.
• At the elevation of Denver, the pressure is 0.82 atm. Express the sulfur dioxide standard at that pressure and a temperature of 15oC.
Step 1

The air quality standard for ozone is 80 ppbv.

The temperate (T) is 25ºC.

Convert the unit of temperature as follows:

Step 2

The pressure (P) is 1 atm.

The molecular weight of ozone is 16g/mol.

Convert the air quality standards for ozone in µg/m3 as follows:

Step 3

The air quality standard for ozone...
