Bernoulli's equation is a fundamental equation in fluid dynamics that describes the relationship between fluid pressure, velocity, and elevation along a streamline. It is commonly used to calculate the net force of wind blowing over a structure, such as a house.
Bernoulli's equation can be applied to determine the net force of wind by considering the change in pressure and velocity of the wind as it flows over the surface of the house. This allows us to calculate the difference in pressure on either side of the house, which can then be converted into a net force.
When using Bernoulli's equation to find the net force of wind, we assume that the wind is steady, incompressible, and inviscid. We also assume that the flow is irrotational, meaning there is no rotation or turbulence in the wind.
No, Bernoulli's equation is most accurate for streamlined objects and may not be as accurate for more complex shapes. However, it can still provide a good estimate of the net force of wind on a house.
The angle of wind can have a significant impact on the net force calculated using Bernoulli's equation. For example, if the wind is hitting the house at a perpendicular angle, the net force will be greater compared to if the wind is hitting the house at an angle. This is because the pressure difference between the two sides of the house will be greater when the wind is perpendicular to the house.
