Seepage The seepage velocity is less than the actual flow rate of the liquid or gas in the pores because the fluid moves only through the portion of the cross-sectional area S that is occupied by the pores.

Velocity triangle In turbomachinery, a velocity triangle or a velocity diagram is a triangle representing the various components of velocities of the working fluid in a turbomachine. Velocity triangles may be drawn for both the inlet and outlet sections of any turbomachine. The vector nature of velocity is utilized in the triangles, and the most basic form of a velocity triangle consists of the tangential velocity, the absolute velocity and the relative velocity of the fluid making up three sides of the triangle.

Velocity Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, a quantity that is measured in metres per second (m/s or m⋅s −1) in the SI (metric) system.o have a constant velocity, an object must have a constant speed in a constant direction. Constant direction constrains the object to motion in a straight path (the object's path does not curve).

Velocity Calculation Velocity Calculation. Velocity refers to the speed in a given direction. Velocity refers to a vector measurement of the rate and direction of motion. The scalar or the absolute value magnitude of the velocity vector is the speed of the motion. Velocity is denoted by the symbol 'v'. Velocity is a vector physical quantity; both magnitude and direction are required to define it.

velocity the rate of change in the position of a body moving in a particular direction. Velocity along a straight line is linear velocity. Angular velocity is that of a body in circular motion. Compare speed. An MRI term for the speed of a thing in a particular direction.

Definition of Speed in Physics Speed is the scalar quantity that is the magnitude of the velocity vector. The most common way to calculate the constant velocity of an object moving in a straight line is with the formula:r = d / t. where. = d / twherer is the rate, or speed (sometimes denoted as v, for velocity, as in this kinematics article)d is the distance movedt is the time it takes to complete the movement. By Andrew Zimmerman Jones. Definition: Distance travelled per unit time.

velocity Velocity is a vector expression of the displacement that an object or particle undergoes with respect to time. The standard unit of velocity magnitude (also known as speed) is the meter per second (m/s). Alternatively, the centimeter per second (cm/s) can be used to express velocity magnitude.

- Discharge. Discharge is the volume of flow of water per unit time, often measured in cubic metres per second (or cumecs). In general, discharge increases with distance from the source to the mouth of a river. The extra water enters the river from tributary streams, surface runoff, throughflow and baseflow.Anomalies.

Escape velocity A relative velocity is the velocity of one body with respect to another. Relative escape velocity is defined only in systems with two bodies. For systems of two bodies the term escape velocity is ambiguous, but it is usually intended to mean the barycentric escape velocity of the less massive body.

Speed and Velocity In conclusion, speed and velocity are kinematic quantities that have distinctly different definitions. Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio.

Metre per second Metre per second (U.S. spelling: meter per second) is an SI derived unit of both speed (scalar) and velocity (vector quantity which specifies both magnitude and a specific direction), defined by distance in metres divided by time in seconds.here metres per second are several orders of magnitude too slow to be convenient, such as in astronomical measurements, velocities may be given in kilometres per second, where 1 km/s is 1000 metres per second, sometimes unofficially abbreviated as kps.

Definitions &Translations Fractional anisotropy. Fractional anisotropy is a scalar value between zero and one that describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is isotropic, i.e. it is unrestricted in all directions.

GENERAL FACTS AND CONCEPTS ABOUT GROUND WATER 1 In contrast, velocities of streamflow generally are measured in feet per second. 2  A velocity of 1 foot per second equals about 16 miles per day. 3  The low velocities of ground-water flow can have important implications, particularly in relation to the movement of contaminants. A velocity of 1 foot per day or greater is a high rate of movement for ground water, and ground-water velocities can be as low as 1 foot per year or 1 foot per decade.

Hemodynamics This value is inversely related to the total cross-sectional area of the blood vessel and also differs per cross-section, because in normal condition the blood flow has laminar characteristics. For this reason the blood flow velocity is the fastest in the middle of the vessel and slowest at the vessel wall.In most cases the mean velocity is used. There are many ways to measure blood flow velocity, like videocapillary microscoping with frame-to-frame analysis, or laser Doppler anemometry.his value is inversely related to the total cross-sectional area of the blood vessel and also differs per cross-section, because in normal condition the blood flow has laminar characteristics.

- Riffles, another type of coarse deposit, develop beneath the thalweg in locations where the faster flow moves vertically up in the channel. Fluvial landforms. The line of maximum velocity or thalweg moves from side to side within a channel. The dates form a kind of square with a sharp triangle to the south, upon the left bank of the thalweg, which overflows them during floods.

Definitions &Translations Velocity. In kinematics, velocity is the rate of change of the position of an object, equivalent to a specification of its speed and direction of motion. Speed describes only how fast an object is moving, whereas velocity gives both how fast and in what direction the object is moving.

Average Speed Average speed is defined as the total distance travelled divided by the total time taken. Average speed is a scalar quantity. The velocity of an object is defined as the displacement divided by the time internal during which the displacement occurred. Since displacement is a vector quantity, average velocity is also a vector quantity.

INSTANTANEOUS VELOCITY The definition of instantaneous velocity. For any equation of motion s(t), we define what we call the instantaneous velocity at time t-- v(t) -- to be the limit of the average velocity, , between t and t + Δt, as Δt approaches 0. The instantaneous velocity is the value of the slope of the tangent line at t. Example 1.

Velocity Velocity is a physical vector quantity; both magnitude and direction are needed to define it. The scalar absolute value (magnitude) of velocity is called speed, a quantity that is measured in metres per second (m/s or m⋅s −1) in the SI (metric) system.or example, 5 metres per second is a scalar (not a vector), whereas 5 metres per second east is a vector. If there is a change in speed, direction, or both, then the object has a changing velocity and is said to be undergoing an acceleration.
