Q$.$ Compute the effective stack height of a coal burning power

plant with physical stack height of $200m$ and stack

diometer of $0\mathrm{.}8m,$ stack gas exist velocity of $18\mathrm{.}3\frac{m}{sec},$ tempont

of gas $190C,$ when the ambient air temperature is $8C$

$8$ atmospheric pressure is $1000$ millibars and average wind

speed is $4\mathrm{.}5\frac{m}{sec}.$ Also compute the emission rate of

sulphure dioxide of the plant assuming buining of $24,008$ tonnes

of col per day with a sulphure content of $4\mathrm{.}2\%$
