Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
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 difference between flow rate and flow velocity in flow tubes?
velocity is the speed of the flow (for example, meters/sec.) Flow rate is the volume per unit time (example: liters/sec.)
What formula is density multiplied by velocity?
it can be asumed as mass flow rate per unit area
Explain Why Nozzles are made convergent and Divergent?
According to Bernoulli's principle, pressure head, velocity head, and datum head are constant between two points. Additionally, continuity equation is area*volumetric flow rate is constant. So, in the convergent section, area is low which will result higher velocity and lower pressure. In the divergent section, area will increase, velocity will decrease, and consequently, pressure will increase.
What is the relationship between river depth and width and velocity of flow?
Manning equation if the hydraulic radius decreases then the velocity decreases
What is the relationship between cross sectional area of blood vessel and velocity of blood flow in that vessel?
Proceeding downstream from the aorta, branching of arterial vessels increases total cross-sectional area and thus results in diminished velocity of blood flow from the aorta to the capillaries. Velocity increases from the capillaries to the large veins with the confluence of vessels and the resulting decrease in total cross-sectional area. :)
What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
Differentiate between steady flow and pipe unsteady flow?
The velocity is constant in a steady flow pipe while in the unsteady flow the velocity is not constant.
What is Kinematic similarity?
A relationship between fluid-flow systems in which corresponding fluid velocities and velocity gradients are in the same ratios at corresponding locations.
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 difference between flow rate and flow velocity in flow tubes?
velocity is the speed of the flow (for example, meters/sec.) Flow rate is the volume per unit time (example: liters/sec.)
Do velocity of blood flow in arteries become faster in big area?
no
How do you find out water velocity in pipe?
Hello, Velocity in a pipe is the flow divided by the area. If the pipe is full, the area is simply pi*r². Here is a useful calulator for full pipes: http://www.tasonline.co.za/toolbox/pipe/velocity.htm
When measuring the flow of liquid what are the two things to measure?
Velocity of fluid. Area of pipe.
What is the equation for water flow in construction?
the velocity of water flow within a drainage pipe; the equation is V=L/t L= Length t=time. Then the flow rate; Fr=A*V, Where A= sectional area and V = velocity.
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.
