What does the Reynolds number represent in fluid dynamics?
The Reynolds number in fluid dynamics represents the ratio of inertial forces to viscous forces in a fluid flow. It helps determine whether the flow is laminar or turbulent.
Reynolds number in terms of inertial force and viscous force?
The Reynolds number is a dimensionless quantity used to predict flow patterns in different fluid flow situations. It is defined as the ratio of inertial forces to viscous forces in a fluid flow. A high Reynolds number indicates that the flow is more turbulent, while a low Reynolds number suggests that the flow is more laminar.
Physical significance of froude number in agitation?
The Froude number in agitation is a dimensionless parameter that relates the inertial forces to gravitational forces. It is used to determine the regime of flow in agitated systems, indicating whether the flow is primarily influenced by inertia or gravity. A low Froude number indicates a flow dominated by gravity, resulting in more settling and less mixing, while a high Froude number indicates a flow dominated by inertia, leading to more turbulent mixing and suspension of particles.
What is called the ratio of magnitude of the forces acting on each point charge separated by certain distance is?
The ratio of the magnitude of the forces acting on each point charge separated by a certain distance is called the electric field strength. It is a measure of the influence that a source charge has on other charges in its vicinity. Mathematically, it is given by the force per unit charge.
What is the ratio of the net force exerted on an object and its acceleration?
The ratio of the net force exerted on an object to its acceleration is equal to the object's mass. This relationship is known as Newton's second law of motion, which states that F = ma, where F is the net force, m is the mass of the object, and a is its acceleration.
