The Centralia power plant emits SO2 at the rate of 150 g/s. It has an effective stack height of 50 m. Surface winds at 10 m are steady at 2.5 m/s and it is a fall afternoon.
a) Calculate the ground level SO2 concentration in ug / m3 at a point 4 km downwind and 0.1 km in the cross wind direction.
b) What is the maximum downwind concentration and at what distance does this occur?
c) There is a town with an SO2 monitor 20 km downwind of the power plant. How large can Q in g/s be if SO2 concentrations are to be kept below 365 ug/m3 for the conditions listed

The earth’s magnetic field: The earth acts as a magnet and the lines of force produced by it follow the pattern shown in the diagram below. If the Earth were completely symm
In certain ranges of a piano keyboard, more than one string is tuned to the same note to provide extra loudness. For example, the note at 110 Hz has two strings at this frequency.
Copper losses: These losses occur because of ohmic resistance of the transformer windings. If I1 and I2 are primary and secondary currents correspondingly and R1and R2 are the res
