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 use Bernoulli's theorem. Here’s a step-by-step solution: ### Step 1: Understand the Problem We have air flowing horizontally over a plane roof. The speed of the air is given, and we need to find the lift force acting on the roof due to the difference in pressure above and below the roof. ### Step 2: Identify Given Values - Speed of air, \( v = 108 \, \text{km/hr} \) - Area of the roof, \( A = 20 \, \text{m}^2 \) ...
