What is the largest sediment that can be transported by a stream that has a velocity of 125 cm per sec?
The largest sediment that can be transported by a stream is determined by the stream's velocity and the sediment's size and weight. Generally, a stream with a velocity of 125 cm per second can transport larger particles, such as gravel or small boulders, depending on factors like flow turbulence and sediment density. However, specific calculations using the Einstein-Brown equation or other sediment transport formulas can provide a more precise size estimate. Typically, at this velocity, the largest sediment might be around 2 to 4 millimeters in diameter.
What is the approximate minimum stream velocity needed to keep a particle in motiob that has a diameter of 10 cm?
The approximate minimum stream velocity needed to keep a particle in motion, such as a sphere with a diameter of 10 cm, can be estimated using Stokes' law and the concept of terminal velocity. For a particle in a fluid, the minimum velocity needed to keep it suspended typically equals the settling velocity, which depends on factors like fluid density and viscosity. In general, for a 10 cm diameter particle, the minimum velocity can range from about 0.1 to 0.5 meters per second, depending on the specific fluid properties.
What is the minimum water velocity necessary to maintain movement of 0.1-centimeter-diameter particle in a stream?
The minimum water velocity required to keep a 0.1-centimeter-diameter particle suspended in a stream can be estimated using the Stokes' law for sedimentation. For small particles, the settling velocity is influenced by factors such as particle size, density, and the viscosity of the fluid. Generally, a velocity greater than the particle's settling velocity is needed to maintain suspension. Calculating the exact value would require specific details about the particle's density and the fluid's viscosity, but velocities typically range from a few centimeters per second for such small particles in water.
What can a stream flowing at a velocity of 100 cm sec can transport?
A stream flowing at a velocity of 100 cm/sec can transport a variety of materials, including sediments, organic matter, and debris. The capacity to carry these loads depends on the stream's flow rate, depth, and the size and density of the transported materials. Larger and heavier particles may settle to the bottom, while finer sediments can be suspended in the water column. Overall, faster streams can carry more substantial loads compared to slower ones.
Why does a ping pong float with a hair dryer?
When you point a running hair dryer upward, and place a ping pong ball in the air stream, it will eventually float somewhere above the hair dryer and near the air stream. It stays above the dryer because the drag of the air balances out the ball's 2.7 grams of mass, and near the air stream due to the Bernoulli effect. The Bernoulli effect is the drop in pressure when a fluid's velocity increases; you can demonstrate it by blowing over the top of a piece of paper. It is partly responsible for the lift generated by an airplane's wing. The ball is drawn towards the center of the air stream due to the increasing velocity and the resulting Bernoulli force, but is pushed away by the air glancing off its surface. The ball maintains a position where these forces balance out, perhaps wobbling back and forth so the average forces balance out.
What is the difference between stream discharge and stream velocity?
Stream discharge is a product of the velocity and the area of the stream (velocity x width x depth), and has units of volume per time (e.g. cubic feet per second, cubic meter per day, etc). Stream velocity is the vector describing the speed of the water and has units of length per time (feet per second, meter per second). Stream discharge is relatively constant as you move up and down a stream, while velocity will change predominately as you change depth. The velocity of water is lowest near the bed of the stream, and highest at the surface.
What is the average velocity of this stream as measured by the virtual stadia rod and velocity sensor?
.64
What depth should a velocity sensor be placed to estimate a stream's average velocity if it's 12.5 meters deep?
The velocity sensor should be placed at approximately 40-60% of the total water depth, so in this case, it should be placed at around 5-7.5 meters from the surface to estimate the stream's average velocity accurately. Placing it in this range helps account for variations in velocity across the vertical profile of the stream.
What is stream velocity?
Stream velocity refers to the speed at which water flows in a stream or river. It is typically measured in meters per second or feet per second and can vary depending on factors such as channel geometry, slope, and discharge. Stream velocity is an important parameter in hydrology and river engineering for understanding water movement and erosion processes.
What stream velocity would be required to carry the smallest boulders?
The stream velocity required to carry the smallest boulders is typically around 1 meter per second. This velocity is based on the sediment transport capacity of the stream, which is influenced by factors such as the size and weight of the boulders, as well as the stream's gradient and flow rate.
What is the slowest stream velocity necessary for a stream to carry the smallest boulders?
The slowest stream velocity necessary for a stream to carry the smallest boulders typically ranges between 1.5 to 2.5 meters per second (about 5 to 8 feet per second). This velocity allows the water to generate sufficient lift and transport capacity to overcome the weight of the boulders. Variability in streambed material, boulder shape, and water density can affect the exact velocity required.
What is the definition of stream velocity?
Stream velocity is the speed at which water flows in a stream or river. It is typically measured in units of distance per time (e.g. meters per second) and can vary based on factors such as gradient, channel shape, and discharge.
What are the largest particles that this stream can transport when its velocity is 200 centimeters per second?
Pebbles
Which part of the stream system has the highest average flow velocity?
The highest average flow velocity in a stream system is typically found in the thalweg, which is the deepest and fastest-moving part of the channel. This primary flow path is where water flows with the least resistance, resulting in higher velocities compared to the edges or shallower areas of the stream.
What are the largest particles that a stream can transport when it's velocity is 200 centimeters per second?
The answer is cobble.
What factor determine the velocity of stream?
measure out ten feet of water, drop a rubber ducky, or some other floating object in the water. and then time it with a stopwatch ti see how long it takes to reach there. Then divide your data by ten to get the data in feet covered per second.
What is an instrment commonly used for measurement of velocity of stream?
A stream gauge is the instrument which is commonly used for the measurement of velocity stream.
