Question
**Tornado Uplift Pressure Calculation** A building has a flat roof and is located 22 meters from the center of a tornado, as illustrated in Figure 1. The building is situated within the free vortex of the tornado, where the wind speed is 20 meters per second at a distance of 40 meters from its center. The density of the air is given as \( \rho_a = 1.20 \, \text{kg/m}^3 \). **Problem Statement:** Determine the uplift pressure on the roof. **Instructions:** Express your answer to three significant figures and include the appropriate units. **Attempt:** - Entered Pressure: \( p = 79.34 \, \text{Pa} \) - Result: Incorrect. Please try again; 4 attempts remaining. **Figure Description:** The illustration shows a tornado with a spiraling vortex. A building is located near the base of the tornado. The vortex is represented with swirling lines, indicating the movement and speed of the wind. **Action Required:** Adjust your calculation based on the provided information and attempt to determine the correct pressure exerted on the roof of the building.
