Which is longest a yard or a meter?
A meter (or metre) is slightly longer. A yard is about 90 centimeters.A meter (or metre) is slightly longer. A yard is about 90 centimeters.A meter (or metre) is slightly longer. A yard is about 90 centimeters.A meter (or metre) is slightly longer. A yard is about 90 centimeters.
Is a yard and a meter the same?
No, a meter is longer.
Is longer three feet or a meter?
A meter is a bit longer than three feet.
Is one meter longer or shorter than nine decimeters?
1 meter = 10 decimetersso 1 meter is longer than 9 decimeters
What is longer 1feet or 1meter?
One meter is longer.
Which times divergent cone is bigger than convergent cone in venturimeter?
why lenght of divergent cone is larger than convergent cone in venturi meter
What is the difference between convergent divergent nozzle and venturi tube?
In case of venturi meter, at the diverging section mach number is less than 1. however in diverging section of a nozzle mach number is greater than 1.
Why is coefficient of discharge of venturi meter is more than coefficient of discharge of orifice meter?
In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.
Why the divergent section of a venturimeter is longer than the convergent section?
The divergent section of a venturi meter is longer than the convergent section to gradually decrease the fluid velocity and increase the pressure after the throat, which helps in recovering some of the kinetic energy as pressure energy, reducing energy losses and ensuring accurate flow rate measurement. This design also helps to minimize turbulence and pressure drop in the system.
Why is the length of the diverging section in a venturi meter longer than the converging?
The length of the diverging section in a venturi meter is longer than the converging section to allow the flow to gradually return to its original pressure and velocity. This helps minimize energy losses and turbulence, ensuring accurate flow measurement. The design aims to maintain steady flow conditions for optimal performance of the venturi meter.
Fluid mechanics in venturi meter?
Venturi Meter is a device used for measuring the flow of the fluid.
How accurate is a venturi meter?

What is flow in venturimeter?
Flow in a venturi meter refers to the rate at which a fluid passes through the device. The flow of fluid is measured by the pressure difference created between the converging and diverging sections of the venturi meter. This pressure difference is directly related to the flow rate of the fluid passing through the venturi meter.
Why the divergent part of venturimeter is longer than convergent part?
Actually when the flow emerges from the throat area of venturi to enter into the diverging section, their is a negative pressure gradient i.e, in layman terms fluid is trying to flow from low pressure region to high pressure region according to Bernoulli equation. In this adverse pressure gradient, there is boundary layer separation, in simple terms, the fluid leaves the surface of the wall. Due to this there can be energy loss or the fluid can't recover the pressure fully leading to head loss. So if divergent section is long that means more gradual diverging section, due to which the adverse pressure gradient is less so less chance of boundary separation and hence less loss. Also large diverging section will ensure proper development of flow, i.e. fluid sticking to the wall back after separation.
Tell me the main uses of venturi meter?
The discharge coefficient is near unity and Non-recoverable net head loss is very small.
What is the order of efficiency of venturi meter orifice meter and rotoameter?
The orifice plate can easily be changed to accomodate widely different flow rates, whereas the throat diameter of a venturi is fixed, so that its range of flow rates is circumscribed by the practical limits of Dp.The orifice meter has a large permanent loss of pressure because of the presence of eddies on the downstream side of the orifice-plate; the shape of the venturi meter prevents the formation OS these eddies and greatly reduces the permanent loss.The orifice is cheap and easy to install. The venturi meter is expensive, as it must be carefully proportioned and fabricated. A home made orifice is often entirely satisfactory, whereas a venturi meter is practically always purchased from an instrument dealer.On the other hand, the head lost in the orifice for the same conditions as in the venturi is many times greater. The power lost is proportionally greater, and, when an orifice is inserted in a line carrying fluid continuously over long periods of time, the cost of the power may be out of all proportion to the saving in first cost. Orifices are therefore best used for testing purposes or other cases where the power lost is not a factor, as in steam lines.However, in spite of considerations of power loss, orifices are widely used, partly because of their greater flexibility, because installing a new orifice plate with a different opening is a simpler matter. The venturi meter can not be so altered. Venturi meters are used only for permanent installations.It should be noted that for a given pipe diameter and a given diameter of orifice opening or venturi throat, the reading of the venturi meter for a given velocity is to the reading of the orifice as (0.61/0.98)2, or 1:2.58.(i.e. orifice meter will show higher manometer reading for a given velocity than venturi meter).
