The speed at which air comes out of a standing fan depends on several factors, including the fan's design, size, and power. Here are some typical air speeds for different types of standing fans:

- Small personal fans: These fans, often used on desks or tabletops, can generate air speeds of around 10 to 20 feet per second (3 to 6 meters per second).

- Medium-sized floor fans: These fans, commonly used in homes and offices, can produce air speeds ranging from 20 to 30 feet per second (6 to 9 meters per second).

- Large industrial fans: These high-powered fans, employed in factories, warehouses, and other large spaces, can reach air speeds of 30 to 40 feet per second (9 to 12 meters per second) or even higher.

It's worth noting that air speed can vary at different distances from the fan. The air tends to be fastest near the fan blades and can slow down as it moves away. Additionally, fan speeds can be adjustable, allowing you to control the airflow according to your preference.
