A petroleum refinery emits 80 g/sec of SO, from an effective height of 60 m (physical stack height 45 m) in an area with flat terrain. At 8 a.m. on an overcast winter morning when the surface wind (measured at a height of 10 m) is 6 m/sec, what is the ground-level concentration directly downwind from the refinery at a distance of 500 m? What is the concentration at the same distance downwind but at a distance 50 m crosswind from the centerline?

Wind Energy

Wind energy is a renewable energy source that is used to generate electricity by wind power. The term, wind power, means utilization of kinetic energy of wind to generate electricity. Wind energy is termed renewable source energy because it can never be exhausted. There are other renewable energy sources, such as solar energy, geothermal energy, hydropower energy, and so on. All of them contribute to power the thermal energy stations to generate electricity.
