2. A power plant emits 120 lb of fly ash per hour up the stack. The flow rate of the hot gases in the stack is 25 ft?/sec. What is the concentration of the fly ash in (a) micrograms per cubic meter? 3. A stream flowing at 60 gal/min carries a sediment load of 2000 mg/L. What is the sediment load in kilograms per day? 4. The proposed air quality standards for ozone (O) is 0.08 ppmy Express that standard in m3 at 1 atm of pressure and 25 At the elevation of Denver, the pressure is about 0.82 atm. Express the ozone standard at that pressure and at a temperature of 15 C a. b. 5.Assume that the world will burn 44 quads of fossil fuel (coal, oil, and gas) next year For the total mix of fossil fuel, the average energy content is 15,000 Btu/pound, and the

Solution

2) Concentration = (120*453.59)/((60*60)(25*.3048³)) = 21.357 g/m³

=21357000 micro grams/m3
