WOAH! A dust devil was captured in NYC's Central Park earlier today 🌪️ Dust devils are a wind phenomenon similar to tornadoes, but typically smaller and much less intense. They most often occur in the early afternoon when skies are clear and winds are light. The vortex forms when hot air at the surface begins to rise rapidly with much cooler air above it. The hot air then stretches and causes a spinning motion. They are short-lived because cold air eventually gets pulled in and dissipates the d

Larger and heavier dust and dirt particles in the air cannot make the turn due to their inertia, so they fall into the oil and settle to the bottom of the base bowl. Lighter and smaller particles stick to the filtration media in the insert, which is wetted by oil droplets aspirated there into by normal airflow. #jcb #india #backhoeloader #maintenance | Narayan Jadhav
