What is difference between discharge velocity and seepage velocity?
discharge velocity is the quantity of flow that flows through a unit cross sectional area of the soil in a unit time discharge velocity is used to determine the quantity of flow through soil seepage velocity the actual rate of movement of the water as measured with dye tracer for instance, is the seepage velocity
What is the purpose of the Transcranial Doppler?
A Transcranial Doppler is a test used to test blood flow velocity as is flows through the brains blood vessels. Through emitting a high pitched sound, an ultrasound probe is able to measure the velocity of the blood flow.
What does Electromagnetic energy travel in?
It flows through the system and then moves to the left and pi= 3.14 then a dog eats your homework. Whoever reads this is smart.... eyeamawetard!
How can laser Doppler velocimetry be used?
Laser Doppler velocimetry also known as Laser Doppler anemometry, is the technique of using the doppler shift to measure the velocity in transparent fluid flows reflecting surfaces.
Do bubbles reach terminal velocity?
It depends on the type of bubbles. Hydrogen bubbles are often used to visualize aerodynamic flows around models. How you would work out their terminal velocity is by balancing their drag force and buoyancy force. First you would need an estimate of the bubble diameter, somewhere around .025 mm. For water, density of fluid =998 kg/m3 and fluid viscosity = 1.12*10-3 Pa*s FB=density of fluid*volume of bubble*gravity FD=3*pi*fluid viscosity*diameter*velocity of water At the terminal velocity FD=FB, you should have all the other variables, just rearrange to solve for the terminal velocity.
What is the greatest velocity that a boat on a river can attain if the boat's motor moves at 10 km per hr and the river's current is 8 km per hr?
Boat WRT land, downstream 10 + 8 = 18 KMH Boat WRT land, upstream 10 - 8 = 2 KMH Boat WRT water 10 KMH
What is the rate of the current if Jim's motorboat travels downstream at the rate of 15km per hour and going upstream it travels at 7km per hour?
The current flows at 4 kph.The boat motors at 11 kph.
Does a river flow from upstream to downstream?
No, a river only flows one way, they either flow upstream or downstream not both.
What way does st johns river flow?
It flows downstream.
What is the velocity of the blood as it flows through the capillaries?
The average velocity of the blood as it flows through a capillary is 0.00047 m/s.
What is the effect on velocity and pressure if a liquid flows in a convergent pipe?
I think velocity is directly proportionate to its applying pressure.
If a boat is traveling east at 20 kmhr and the river it is on flows west at 5 kmhr what is the velocity of the boat?
20 km/hr - 5 km/hr = 15 km/hr
Do all rivers flow north to south?
No. The water flows downstream. Correction, I believe the Amazon flows upstream
What is the process in which water changes its potential energy to kinetic energy as it moves from upstream to downstream?
That means that the water either flows downstream, or falls down, depending on the case.
How does the gradient of a river affect its flow?
The gradient of a river is mostly flat or downhill which means that as the water flows it is affected by gravity. The steeper the gradient goes downhill, the more gravity will affect the water which will make the water flow faster (increases the velocity).
Why does silt depth increase downstream?
Because as the river slows it deposits more than when it flows fast.
Is Paris France near any oceans?
No. It's on a river which flows into the English Channel 200 miles downstream.
