Air flows horizontally with a speed v = 108 km/hr . A house has a plane roof of area A = 20 `m^(2)` . Find the magnitude of aerodynamic lift on the roof . [ Density of air ` = 1.3 kg//m^(3)`]

Text Solution

AI Generated Solution

To find the magnitude of aerodynamic lift on the roof of the house, we can follow these steps: ### Step 1: Convert the speed from km/hr to m/s The speed of air is given as \( v = 108 \, \text{km/hr} \). To convert this to meters per second, we use the conversion factor \( \frac{5}{18} \). \[ v = 108 \, \text{km/hr} \times \frac{5}{18} = 30 \, \text{m/s} \] ...
