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.
How would you calculate the air velocity to move a drop of liquid into the air stream?
Lots or aeronautic equations, but you'd need a whole lot more data than you have given.
If a boat can go 20 miles per hours in still water and can go six miles downstream and 3 miles up stream in the same time how fast is the river?
assume river velocity = X mph boat velocity = 20 mph time to go 6 miles downstream = T1 time to go 3 miles upstream = T2 distance = time * velocity downstream: 6 mi = T1 * (boat velocity + river velocity) upstream: 3 mi = T2 * (boat velocity - river velocity) 6 = T1 * ( 20 + X ) 3 = T2 * ( 20 - X ) T1 * ( 20 + X ) = 2 * ( T2 * ( 20 - X ) ) since T1 = T2 then 20 + X = 40 - 2X 3X = 20 X = 6.67 thus, river velocity is 6.67mph
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.
Is stream up a compound word?
No. Stream up is not a compound word.
When the velocity of a stream suddenly decreases the sediment being transported undergoes an increase in?
Deposition, whereby the sediment load being transported is dropped.
Which sediment is the largest that could be carried by a stream flowing at a velocity of 100cmsec?
sand
What is the definition of stream load?
Stream load refers to the amount of sediment and materials that are being transported by a stream. It can consist of sand, silt, gravel, and organic matter, and is influenced by factors such as stream velocity, discharge, and erosion within the watershed. Monitoring stream load is important for understanding sediment transport and its impact on water quality and ecosystems.
When sediment is transport down a mountain and along a stream we are seeing the conservation of?
matter
What sediment an example of when it is along a stream?
An example of a sediment found along a stream is sand. Sand particles are typically larger than silt or clay and are commonly found in streambeds or along the banks of rivers and streams. They are transported by the flowing water and deposited when the flow velocity decreases.

What is the relationship between the carrying capacity of a stream and it and discharge and velocity?
The carrying capacity of a stream refers to its ability to transport sediment. Higher discharge and velocity typically increase a stream's carrying capacity as they provide more energy to move sediment. However, if the stream's carrying capacity surpasses its available sediment, deposition can occur.
What is a streams bed load?
Sediment that is carried by a stream along the bottom of its channel.
What could cause a stream to deposit the sediment?
A decrease in stream velocity due to factors such as a decrease in slope or widening of the stream channel can cause sediment to be deposited. When the stream's capacity to transport sediment is exceeded, it drops the sediment it was carrying. Additionally, changes in the stream's flow rate or turbulence levels can also result in sediment deposition.
The greater the time that stream sediment is transportedthe greater the probability that the sediment will become more what?
The greater the time that stream sediment is transported, the greater the probability that the sediment will become more rounded and well-rounded due to abrasion and attrition processes.
Which change at a particular location in a stream usually causes more sediment to be deposited at that location?
Decrease in stream velocity
