Principle of Natural Wind Exhausting:-

Natural wind exhausting of turbine ventilator is decided by three following factors:-

  1. Motivation of natural horizontal wind power.
  2. Indoor and outdoor temperature difference causes air pressure difference which leads to air convection. Forming upright wind power.
  3. According to the Bernouli’s Principle of fluid Mechanics, indoor and outdoor wind speed difference causes air pressure difference which leads to air convection.

 

Bernouli Principle: - The sum of static pressure and dynamic pressure is a constant, i.e. the greater the fluid speed is, the smaller the pressure is.
