How is wind force and direction measured

Web8 nov. 2024 · The formula to calculate the wind pressure on external surfaces is. w e = q p ∗ c p e. Where. q p. is the peak velocity pressure and. c p e. is the external pressure coefficient. The coefficient c p e has 2 different values depending on the wind loaded area. There is a value for a surface area of 1 m 2 and 10 m 2. WebMost ocean waves are generated by wind. Wind blowing across the water’s surface creates little disturbances called , or ripples that start from gentle breezes (Figure 10.2.1).
