Calculation of wind pressure in wind blower
(2) dynamic pressure (Pv): the so-called dynamic pressure is the flow of fluid in the flow of the pressure formed by the pressure, often used in the kgf / m2 or mmaq to represent.
In the duct of the fan, the static pressure in any direction are all fixed and positive and negative points, if the static pressure value is normal that the duct is currently being swollen, if the static pressure is negative, said the duct
(1) static pressure (Ps): the so-called static pressure is applied to the surface of the fluid and the vertical force with the surface, the fan is generally due to the gravity and the fan caused by the promotion,
