What is bend meter in fluid mechanics?
Bend meter is a type of pipe which are bend may be sharply or 90 degree . In fluid mechanics we calculate the losses inside the pipe .in which losses are more.
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 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.
Applications of venturimeter?
1. It is used for flow measerment with minimum head loss. 2. It is used in industries for flow measerment of chemicals. 3. it is also used in the airoplane for measurment of speed of plane.

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.
What is the most common issue encountered when using a venturi meter in a fluid flow system?
The most common issue encountered when using a venturi meter in a fluid flow system is blockage or clogging, which can affect the accuracy of the flow measurement.
What is bend meter in fluid mechanics?
Bend meter is a type of pipe which are bend may be sharply or 90 degree . In fluid mechanics we calculate the losses inside the pipe .in which losses are more.
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 orifice in fluid mechanics?
An orifice in fluid mechanics is a small opening or hole through which fluid flows. It is typically used in devices such as nozzles, Venturi meters, and orifice plates to measure or control the flow rate of a fluid. The size and shape of the orifice affect the flow characteristics of the fluid passing through it.

What is the principle on venturimer works?
A Venturi meter works based on the principle of Bernoulli's equation, which states that an increase in fluid velocity results in a decrease in pressure. The Venturi meter is a device that measures the flow rate of a fluid by creating a pressure difference between two points in a pipe, allowing for flow rate calculations based on this pressure difference.
What is venturi meter?
A Venturi meter is a device used to measure the flow rate of fluids in a pipeline. It consists of a converging section followed by a throat and then a diverging section. The pressure difference between the converging and throat sections is used to determine the flow rate of the fluid passing through the device.
What causes pressure loss for venturi?
Pressure loss in a venturi is typically caused by friction between the fluid flow and the venturi walls, as well as disruption and mixing of the fluid stream. This pressure loss is necessary for the venturi to create a pressure differential, which allows for measurement or control of fluid flow rate.
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 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).
Will there be any flow variations if a venturimeter inlet outlet connections is reversed?
Yes, reversing the inlet and outlet connections of a venturi meter will result in flow measurement errors. The design of the venturi meter relies on the inlet and outlet connections being in a specific orientation to accurately measure fluid flow rates. Reversing the connections disrupts the flow dynamics and can lead to inaccurate readings.
