Air Pollution

2. From the elemental analysis, a waste mixture contains 15% by weight of ash, and the other portion of the mixture can be represented by a chemical formula of C600h1000O400N10s

(a) Use Dulong's formula to estimate the heating value of this waste mixture in Btu/lb,assuming the ash has no heating value.

(b) Convert the heating value of the heat mixture into million Btu/ton

(c) Use the conversion factors between Btu and kJ and between Ib and kg to convert the heating value of the waste mixture into MJ/kg  Verified    ### Question 28908  Air Pollution
