What causes air flow?
Airflow, also known as air flow, refers to the motion of air. It occurs due to the presence of air, which behaves like a fluid and moves from areas of higher pressure to areas of lower pressure. The movement of air is influenced by factors such as altitude, temperature, and composition.
Why is temperature not a variable of airflow in fan law?
Temperature is not considered a variable of airflow in the Fan Law because air, unlike water, is compressible and can expand. The density of air changes depending on factors such as temperature, pressure, and altitude. An increase in pressure results in a decrease in volume and airflow, even with the same amount of air mass.
If you find this concept confusing, it's important to understand that air behaves differently than water due to its compressibility. The variations in temperature can significantly impact the density of air, which consequently affects its flow and pressure. Understanding this relationship is crucial in engineering applications such as fan systems.
How does air pressure change with altitude?
Air pressure varies depending on the altitude. Although invisible, the air surrounding us is affected by gravity, resulting in what we call air pressure. Fortunately, our bodies counteract this pressure by exerting an equal amount of outward pressure.
A graph illustrating the changes in air density and air pressure at different altitudes, or distances above sea level, provides insight into the alterations within the atmosphere.
