pnts$)$ A projected $400$ MW power plant with a stack of $60$m height and $5$m diameter will continuously releases effluents into the ambient atmosphere of temperature $298$K$.$ The exhaust gas temperature and velocity is calculated as $200$oC and $10$ m$/$s$,$ accordingly. The power plant will burn $3500$ tons of coal$/$day and the coal assay indicates $1\mathrm{.}5\%$ Sulphur. Suppose cloudless, hot summer afternoon day with a lapse rate $20$ K$/$km and there is a wind from north to south at a speed of $1\mathrm{.}8$ m$/$s$.$

$(15$ pnts$)$ Calculate mass flow rate $($g$/$s$)$ and volumetric flowrate $($m$3/$s$)$ and mass flow rate to volumetric flow rate ratio $($mg$/$m$3)$ of Sulphur dioxide $($SO$2)$ emitted from the stack.

$(20$ pnts$)$ Calculate the plume rise and effective height of the stack.

$(20$ pnts$)$ Predict the location and magnitude of the maximum ground level concentration of SO$2?$ Compare the maximum ground level concentration with the limit value given in the Turkish Industrial Air Pollution Control Regulation.
