A stack( T=550 deg F and 750mm Hg) was sampled using EPA Method 5. The total gas volume that flowed through the dry gas meter was 2.785 cubic meters (at T = 60 deg F and P = 800 mm Hg). The mass of PM (particulate matter) was 1.50 g. Also, 72.0 g of H20 was collected in impingers.

a. Calculate the concentration of PM in the stack (micrograms/cubic meter) at stack conditions.

b. The stack gas exits at an average velocity of 20 m/s and the stack has an inside diameter of 5m. What is the emission rate of PM, in kg/day?

c. What is the PM concentration in micrometers/dcsm?
