👉 lpm is a unit of measure commonly used in engineering and physics to describe the rate at which something is moving. It's often expressed as RPM (revolutions per minute), where 1 revolution equals one full cycle of rotation. For example, if you have an engine that's running at 5000 rpm, it means it's rotating 5000 times every second. This is important because it helps engineers understand how quickly the engine is turning and how efficiently it's doing
