Question

3. Given: Wind velocities were measured on the wall of a building as shown below. The wall is 85 ft long. Distance from top of building Wind velocity (mph) 25 17 12 16 31 45 The pressure of the wind on the wall can be computed using: Pressure x (density of air) x (wind speed)2 You may assume a density of air of 1.25 kg/m3. Find: (a) Prepare a scatter chart formatted in the usual way with distance from the top of the building on the vertical axis and air pressure on the horizontal axis. Format the data series with no markers and solid black lines. Copy your scatter chart into your solution. b) The total wind force on the wall in kN by manual calculation (c) Compute the total force on the wall in kips and kN using Excel. Copy your Excel calculations into your solution.
