Vehicular emissions contributed more than half of Delhi's particulate pollution between October 24-November 8, the Centre for Science and Environment think tank said in its report published on Thursday. NEW DELHI (Reuters) - New Delhis air quality plummeted again on Friday, and a thick haze of toxic smog hung over Indias capital due to a drop in temperature and wind speed, and a spike in the. Turbine rated wind speed 15 m/s Minimum wind speed 4 m/s Maximum wind speed 25 m/s Swept area 2828 Rotor diameter 80 m Pitch angle 1 Air density 1.225 kg/m 3 RPM 15: 575/30 KV 2 MVA transformer: Positive sequence data: impedance voltage 6.25 X+/R + 6 Zero sequence data: impedance voltage 6. 5, a day after revellers burnt firecrackers during the Diwali festival, as AQI levels surged to 463 on a scale of 500. Residents of Delhi endured this year's worst air on Nov. India's efforts to reduce crop-waste burning, a major source of air pollution during winter, by spending billions of rupees over the past four years have done little to avert a sharp deterioration in air quality.ĭelhi, often ranked the world's most polluted capital, faces extremely bad air in winter due to the crop stubble burning, emissions from transport, coal-fired plants outside the city and other industrial emissions, open garbage burning and dust. 17.Īir quality might worsen if farm fires continued, as the SAFAR model forecasts calm wind conditions, Beig said. He said current severe conditions may ease by Saturday, but air quality would remain "very poor" until Nov.

like maintenance, critical conditions because of the weather or malfunction, etc. "Fire counts are in the range of 3,000-5,000 and not declining," Beig told Reuters, referring to crop stubble fires in the regions around the capital. On wind power integration into electrical power system: Spain vs. "This is becoming a nightmare," said Gufran Beig, founder project director of air quality and weather monitor SAFAR that falls under the Ministry of Earth Science. The influence on the controllers performance due to the addition of an offshore wind farm converter into the existing link was examined considering different wind power profiles. PM2.5 is small enough to travel deep into the lungs, enter the bloodstream and can cause severe respiratory diseases, including lung cancer. The government prescribes a "safe" PM2.5 reading at 60 micrograms per cubic meter of air over a period of 24 hours. The concentration of poisonous PM2.5 particulate matter averaged 329 micrograms per cubic meter of air.

This level of pollution means the air will affect healthy people and seriously impact those with existing diseases. The haze reduced visibility and the Air Quality Index (AQI) hit 461 on a scale of 500, according to the federal pollution control board. NEW DELHI (Reuters) - New Delhi's air quality plummeted again on Friday, and a thick haze of toxic smog hung over India's capital due to a drop in temperature and wind speed, and a spike in the burning of crop waste in surrounding farmlands.
