What forces act at air particle at curved streamline, looking from inertial and non-inertial frame of reference? (show free body diagram)
A fluid streamline curve is an imaginary line that represents the path of a fluid particle as it moves through a fluid. It is often used in fluid mechanics to study the behavior of fluids.
The forces acting on an air particle along a fluid streamline curve include pressure, gravity, and viscous forces. Pressure is the force exerted by the fluid on the particle, gravity is the force pulling the particle towards the ground, and viscous forces are caused by the friction between the fluid and the particle's surface.
The shape of a fluid streamline curve can greatly affect the forces on an air particle. For example, a curved streamline can create a pressure gradient, causing the particle to experience a net force in the direction of the curve. A streamline with a sudden change in direction can also create a vortex, resulting in a swirling motion of the particle.
Yes, the forces acting on an air particle along a fluid streamline curve can change. This is because the shape of the streamline can change due to external factors such as obstacles or changes in the flow of the fluid. Additionally, the properties of the fluid, such as its viscosity, can also affect the forces on the particle.
Understanding the forces on an air particle along a fluid streamline curve is crucial in many fields, such as aerodynamics, hydrodynamics, and meteorology. It allows us to predict the behavior of fluids and their interactions with objects, which is important in designing efficient structures and predicting weather patterns.
