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).
When is the speed of a fluid maximum in a venturi meter?
from the continuity equation A1v1 = A2v2 according to the continuity equation as the area decreases the velocity of the flow of the liquid increases and hence maximum velocity can be obtained at its throat
What are the difference between 0.2 and 0.2S class in metering CT?
The 0.2S class is more accurate in meter reading than the 0.2 class. The 0.2S class is now mandatory for all meter reading.
Advantages of using a pH meter?
With the help of pH meter we can get the nature of any liquid rather it is acidic or basic.Gives a numerical valueSimple to useExact pH
Fluid mechanics in venturi meter?
Venturi Meter is a device used for measuring the flow of the fluid.
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.

What is venturi meter?
Measuring flow of a fluid based on Bernoulli's principle.
What is Venturi as defined with pictures?
What is a Venturi?
What is the birth name of Rick Venturi?
Rick Venturi's birth name is Rick J. Venturi.
What is the birth name of Ken Venturi?
Ken Venturi's birth name is Kenneth Paul Venturi.
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.
Which times divergent cone is bigger than convergent cone in venturimeter?
why lenght of divergent cone is larger than convergent cone in venturi meter
In life with derek Is marti venturi youngest in the McDonald venturi family?
Yes. Marti is the youngest Mcdonald/Venturi.
Why meter stick is accurate for measuring?
It is not accurate. It is very much a "rough-and-ready" approximation.
