When stream flow decreases to below the critical settling velocity of a certain size particle, the particle will settle out of suspension and deposit on the streambed. This process is known as sediment deposition and is influenced by factors such as stream velocity, particle size, and sediment concentration.

What occurs when stream flow decreases to below the critical setting velocity of a certain size particle?
When stream flow decreases below the critical settling velocity of a certain size particle, the particle will settle out of the flow and deposit on the streambed. This process is known as sedimentation and can lead to the formation of sediment layers along the stream channel. Over time, these deposits can alter the shape and depth of the stream channel.
What is the approximate minimum stream velocity needed to move a particle with a diameter of a 6.4 moving?
The approximate minimum stream velocity needed to move a particle with a diameter of 6.4 can be determined using the equation for the critical velocity of sediment transport. For a particle of this size, the critical velocity is typically around 0.3-0.4 m/s in most natural streams and rivers.
What is the minimum velocity that a stream must have in order to transpport particles with diameter equal to 0.04?
The minimum velocity required to transport particles with a diameter of 0.04 in a stream is known as the critical velocity. It can be calculated using the Shields criterion, which takes into account the particle size, density, and fluid properties. The critical velocity is the velocity needed to start moving the particle and overcoming the forces acting on it due to gravity and drag.
What is the momentum of a resting particle?
The momentum of a resting particle is zero, as momentum is the product of an object's mass and velocity, and velocity is zero when the particle is at rest.
What is the settling velocity in specific gravity of the solid particles?
The settling velocity of solid particles in a fluid depends on the size, shape, density difference, and viscosity of the fluid. It can be calculated using Stokes' law, which considers these factors to determine the terminal velocity of a particle settling under gravity in a fluid. The settling velocity increases with increasing density difference and particle size, and decreases with increasing fluid viscosity.

When stream flow decreases to below the critical settling velocit of a certain size particle occurs?
When stream flow decreases below the critical settling velocity of a certain size particle, the particle will settle out of the water column and deposit on the bed of the channel or river. This process is known as sediment deposition and can contribute to changes in channel morphology and habitat.
What is the approximate minimum stream velocity needed to move a particle with a diameter of a 6.4 moving?
The approximate minimum stream velocity needed to move a particle with a diameter of 6.4 can be determined using the equation for the critical velocity of sediment transport. For a particle of this size, the critical velocity is typically around 0.3-0.4 m/s in most natural streams and rivers.
How to know whether the velocity of a particle increases or decreases?
If the velocity of a particle increases, its speed is getting faster over time. If the velocity decreases, the particle's speed is slowing down. This change can be measured by observing the rate at which the velocity is changing in relation to time.
Difference between turbulent flow and streamlined flow?
Streamline flow:The flow of a fluid is said to be streamline (also known as steady flow or laminar flow), if every particle of the fluid follows exactly the path of its preceding particle and has the same velocity as that of its preceding particle when crossing a fixed point of reference.Turbulent flow:The flow of a fluid is said to be turbulent or disorderly, if its velocity is greater than its critical velocity. Critical velocity of a fluid is that velocity up to which the fluid flow is streamlined and above which its flow becomes turbulent. When the velocity of a fluid exceeds the critical velocity, the paths and velocities of the fluid particles begin to change continuously and haphazardly. The flow loses all its orderliness and is called turbulent flow.
What is the minimum velocity that a stream must have in order to transpport particles with diameter equal to 0.04?
The minimum velocity required to transport particles with a diameter of 0.04 in a stream is known as the critical velocity. It can be calculated using the Shields criterion, which takes into account the particle size, density, and fluid properties. The critical velocity is the velocity needed to start moving the particle and overcoming the forces acting on it due to gravity and drag.
When is the velocity vector of a particle tangent to the path of the particle?
The velocity vector of a particle is tangent to the path of the particle at any point. This is because velocity is a vector that points in the direction of motion of the particle at that particular instant.
What is the momentum of a resting particle?
The momentum of a resting particle is zero, as momentum is the product of an object's mass and velocity, and velocity is zero when the particle is at rest.
A small slope on a velocity vs. time graph indicates a small acceleration true or false?
It depends on whether it is a positive slope or a negative slope. If the velocity increases as time goes on, yes the particle is accelerating. If the velocity decreases as time goes on, it is decelerating.
What is the settling velocity in specific gravity of the solid particles?
The settling velocity of solid particles in a fluid depends on the size, shape, density difference, and viscosity of the fluid. It can be calculated using Stokes' law, which considers these factors to determine the terminal velocity of a particle settling under gravity in a fluid. The settling velocity increases with increasing density difference and particle size, and decreases with increasing fluid viscosity.
What will happen to the wavelength associated with a moving particle if its velocity is reduced to half?
If the velocity of a moving particle is reduced to half, the wavelength associated with it will remain the same. The wavelength of a particle is determined by its momentum, not its velocity.
If velocity decreases then does its momentum?
Yes, if the velocity of an object decreases, its momentum will also decrease. Momentum is directly proportional to velocity, so as the velocity decreases, the momentum will decrease correspondingly.
