WebAfter a lot of googling, I found Table 4 of the standard in a Branz article and learned that level 2 is the airtightness of your window ('recommended for air-conditioning and other demanding situations'). It is 2 litres per second per metre ² at 150 pa of air pressure. WebThe dynamic pressure associated with the wind flow is related to its kinetic energy, so the basic pressure is proportional to the square of the speed. The formula used is pressure = 0.6 x speed 2. A Pitot tube is used to measure dynamic pressure directly (see Figure 1).
