Air volume and air pressure

This post was last edited by wpw121 on 2011-3-6 08:57. Is it possible to increase the air volume of a fan while keeping the wind pressure at its outlet constant? ? :)
Looking at the fan curve, it seems quite difficult to do, right? What is the purpose of making such adjustments? It seems unnecessary
One way is to increase the outlet pipe diameter or increase the resistance in the outlet pipe. The fan’s air volume increases, and the wind speed increases as well ； As the wind speed increases, the dynamic pressure head becomes very large ； As a result, the wind pressure increases. p=ps+pk
