Sandblasting technology uses high-speed abrasive particles, typically propelled by compressed air, to strip, clean, or reshape surfaces. Originally, silica sand was a common abrasive, but due to health hazards like silicosis, it has largely been replaced by safer alternatives such as aluminum oxide, glass beads, and garnet. The physics behind sandblasting revolves around Newton’s laws of motion and kinetic energy transfer. When abrasive particles collide with a surface at high velocity, their mo

Which Car Is This Cooling Coil? Car AC coils, also known as evaporator and condenser coils, play a crucial role in the air conditioning system. Here’s a brief guide on them: 1. Types of Coils in Car AC Evaporator Coil (Located inside the dashboard) Function: Cools the air inside the cabin. Common Issues: Dirt buildup, leakage, corrosion. Maintenance: Clean with coil cleaner or compressed air, check for leaks. b) Condenser Coil (Located in front of the radiator) Function: Releases heat absorbed f
