Momentum thickness is a measure of the boundary layer thickness in a fluid flow. It represents the distance over which the momentum of the fluid decays as it moves through the boundary layer. A larger momentum thickness indicates a thicker boundary layer and therefore a slower rate of momentum decay near the surface.
Momentum thickness is a physical length scale to quantify the effects of fluid viscosity in the vicinity of the boundary layer. It is the distance that the flow would be displaced by to have the same momentum as an ideal fluid. A no slip condition at the wall and a known velocity profile can be used with the differential of momentum thickness with distance to calculate (local) wall shear stress. This expression can be integrated over a length to find total drag.

Is viscosity a chemical or physical properties?
It is a physical property :)
What is meant by momentum?
Momentum refers to the quantity of motion an object has. It is calculated by multiplying an object's mass by its velocity. In physics, momentum is a vector quantity, meaning it has both magnitude and direction.
What is the property of moving object that depends upon the object's mass and moving velocity?
The property that depends on an object's mass and velocity is its momentum. Momentum is calculated as the product of an object's mass and its velocity. It is a vector quantity, meaning it has both magnitude and direction.
Is momentum conserved in a perfectly inelastic collision?
In any physical process, momentum will always be conserved. Momentum is given by p = m*v. There is also something called law of conservation of momentum.
What is the example of physical self?
The meaning of physical self is the physical qualities of a person...
What is physical significance of momentum?
Physically, linear momentum is "stored force" as that momentum is dissipated. Consider the linear momentum of a train carrying coal coming to a stop, quickly.
What is physical meaning of momentum?
Momentum is the physical movement of mass m with speed v or velocity V creates momentum p =mv or p=mV. Every spec of moving mass creates momentum. This makes momentum a very big deal in physics. Momentum also creates scalar and vector energy cp and cP. Vector Momentum Energy cP is the mysterious "Dark Energy". it is mysterious because physicists define energy as a scalar and thus overlook, vector energy. The famous Tangent Vector Force F=mdV/dt is the Momentum Force dcP/dr = dcP/cdt = dP/dt = dmV/dt = mdV/dt.
What is momentum apart from physical quantity?
an unchanging state
In quantum physics what is a quantum?
A quantum is the smallest possible discrete unit of a physical property, such as energy or momentum. In quantum physics, properties like energy and momentum are quantized, meaning they can only take on certain specific values. This concept is fundamental to understanding the behavior of particles on a very small scale.
What is momentum of the ship?
The momentum of a ship is the product of its mass and velocity. It is a vector quantity, meaning it has both magnitude and direction. The momentum of the ship can be calculated using the formula: momentum = mass x velocity.
What is a property of momentum?
One property of momentum is that it is a vector quantity, meaning it has both magnitude and direction. This allows us to analyze the motion of objects in terms of how their momentum changes in different directions. The momentum of an object is conserved in a closed system, meaning the total momentum before an event is equal to the total momentum after the event.
What forces influence momentum?
The momentum of an object is influenced by its mass and velocity. Increasing the mass or speed of an object will increase its momentum, while decreasing either will decrease momentum. Momentum is a vector quantity, meaning both the direction and magnitude of an object's velocity impact its momentum.
Can momentum be created or destroyed during a collision?
Momentum is conserved in a collision, meaning it cannot be created or destroyed. The total momentum before the collision is equal to the total momentum after the collision in a system with no external forces.
What is physical significance of linear momentum?
Linear momentum is a measure of an object's motion and is equal to the product of its mass and velocity. It quantifies how difficult it is to stop or change the motion of an object. In physical systems, the conservation of linear momentum plays a key role in describing and predicting the behavior of objects in motion.
What is the Medical term meaning thickness of blood?
viscosity
How do calculate the gate thickness for a parallel gate valves?
The ideal thickness will have no obstruction in flow, meaning that no friction will be lost.
What happens to the hammer's momentum after the hammer hits the nail?
After the hammer hits the nail, its momentum is transferred to the nail causing it to move. Momentum is conserved in the system, meaning that the total momentum of the hammer and nail before and after the collision remains the same.
