What is the wind pressure per square meter?

1. calculation formula: wp=v/ 1600 wp is wind pressure [kn/m], and v is wind speed [m/s].

"Wind pressure is the wind pressure on the plane perpendicular to the direction of airflow. According to the relationship between wind and pressure obtained by Bernoulli equation, the dynamic pressure of wind is wp=0.ro( 1).

Where wp is wind pressure [kN/m], ro is air density [kg/m], and V is wind speed [m/s].

Because the relationship between air density (ro) and gravity (R) is r=ro? G, so there is ro = r/g. Using this relationship in (1), we get

wp=0。 /g (2)

This formula is the standard wind pressure formula. In the standard state (air pressure is 10 13 hPa, temperature is15 C), air gravity r=0.0 1225 [kN/m], and gravity acceleration g=9.8[m/s] at latitude 45.

2. Tropical depression: 6-7 (per second 10.8- 17. 1 m)

Tropical storm: 8-9 (17.2-24.4m/s)

Severe tropical storm: 10- 1 1 (24.5-32.6 meters per second)

Thirdly, if the wind pressure is calculated as 10 and the wind speed is 25m/s, the wind pressure is = 252/1600 = 0.390625kn/m.
