Overview:
Clemens Herschel (March 23, 1842 – March 1, 1930) was an American hydraulic engineer. He is best known for developing the Venturi-meter, which was the first large-scale, accurate device for measuring water flow.
A Venturi-meter is a device used for measuring the rate of flow of a fluid flowing through a pipe.
It is used to calculate the velocity of fluids running through a pipeline.
The fluid may be a liquid or a gas.
By reducing the cross-section area of flow passage, a pressure difference is created and the measurement of pressure difference enables the determination of discharge through pipe.

A fluid is a state of matter in which its molecules move freely and do not bear a constant relationship in space to other molecules.
In physics, fluid flow has all kinds of aspects: steady or unsteady, compressible or incompressible, viscous or non-viscous, and rotational or irrotational to name a few. Some of these characteristics reflect properties of the liquid itself, and others focus on how the fluid is moving.
Fluids are :-
Liquid : blood, i.v. infusions)
Gas : O2 , N2O)
Vapour (transition from liquid to gas) : N2O (under compression in cylinder), volatile inhalational agents (halothane, isoflurane, etc)
Sublimate (transition from solid to gas bypassing liquid state) : Dry ice (solid CO2), iodine
In fluid Mechanics course pressure measurement with different devices is much important. In this slides we will learn different pressure measuring devices.

INTRODUCTION— The flow of a fluid (liquid or
gas) through pipes or ducts is a common part of many
engineering systems. Household applications include
the flow of water in copper pipes, the flow of natural
gas in steel pipes, and the flow of heated air through
metal ducts of rectangular cross-section in a forced-air
furnace system. Industrial applications range from the
flow of liquid plastics in a manufacturing plant, to the
flow of yogurt in a food-processing plant. Because the
purpose of a piping system is to transport a desired
quantity of fluid, it is important to understand the
various methods of measuring the flow rate.
In order to work with a fluid system, and certainly to
design a fluid system that will deliver a prescribed
flow, it is necessary to understand certain fundamental
aspects of the fluid flow. For this, one should be able
to answer questions like: Are compressibility effects
important? Is the flow laminar or turbulent? Is the
viscosity of the fluid important or not? Is the flow
steady or varying with time? What are the primary
forces of importance? For internal ...

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

Topic: Orifice meter & Pitot tube

2. ORIFICE METER
The venturi meter is a reliable flow measuring device.
Furthermore, it causes little pressure loss.
For these reasons it is widely used, particularly for large-volume liquid
and gas flows.
However this meter is relatively complex to construct and hence
expensive.
Especially for small pipelines, its cost seems prohibitive, so simpler
devices such as orifice meters are used.
3. PRINCIPAL OF ORIFIC METER
The principle of the orifice meter is identical with that of the venturi meter.
The reduction of the cross section of the flowing stream in passing through
the orifice increases the velocity head at the expense of the pressure head,
and the reduction in pressure between the taps is measured by a manometer.
Bernoulli's equation provides a basis for correlating the increase in velocity
head with the decrease in pressure head.
One important complication appears in the orifice meter that is not found in
the venturi. Because of the sharpness of the orifice, the fluid stream
separates from the downstream side of the orifice plate and forms a free-
flowing jet in the downstream fluid and vena contracta forms.
5. Continue…
It is also known as Pipe orifice & Orifice plate.
It may be installed in pipeline with a minimum of trouble and expense.
Pipe orifice is a device used for measuring the rate of flow of a fluid through
a pipe.
It consists of a thin, circular plate with a hole in it. The plate is held in the
pipeline between two flanges.
Pipe orifice is a cheaper device as compared to venturimeter.
The diameter of orifice is generally 0.5 times the diameter of the pipe (D),
although it may vary from 0.4 to 0.8 times the pipe diameter.
6. Orifice plates can be a surprisingly good way of measuring small gas
flows. To be able to use orifice plates of very small orifice diameter in an
existing installation in a declining gas field may be much more economical
than to replace the metering or shut the field.
From the beginning of the flow measurement to its conclusion a 4″ orifice
meter with different orifice plates (including those described in this
appendix) might measure a range of around 3000:1 in terms of mass flow
rate.
The orifice fitting, which enables the operator to change or remove an
orifice plate easily.
Continue…
7. APPLICATION
Orifice plates are most commonly used to measure flow rates in pipes, when
the fluid is single-phase (rather than being a mixture of gases and liquids, or
of liquids and solids) and well-mixed, the flow is continuous rather than
pulsating, the fluid occupies the entire pipe (precluding silt or trapped gas),
the flow profile is even and well-developed and the fluid and flow rate meet
certain other conditions.
Under these circumstances and when the orifice plate is constructed and
installed according to appropriate standards, the flow rate can easily be
determined using published formulae based on substantial research and
published in industry, national and international standards.
Plates are commonly made with sharp-edged circular orifices and installed
concentric with the pipe and with pressure tapping's at one of three standard
pairs of distances upstream and downstream of the plate.
8. The edges may be rounded or conical, the plate may have an orifice the same
size as the pipe except for a segment at top or bottom which is obstructed,
the orifice may be installed eccentric to the pipe, and the pressure tapping's
may be at other positions. Variations on these possibilities are covered in
various standards and handbooks. Each combination gives rise to different
coefficients of discharge which can be predicted so long as various
conditions are met, conditions which differ from one type to another.
Once the orifice plate is designed and installed, the flow rate can often be
indicated with an acceptably low uncertainty simply by taking the square
root of the differential pressure across the orifice's pressure tapping's and
applying an appropriate constant. Even compressible flows of gases that
vary in pressure and temperature may be measured with acceptable
uncertainty by merely taking the square roots of the absolute pressure and/or
temperature, depending on the purpose of the measurement and the costs of
ancillary instrumentation.

9. Pitot tube
A Pitot tube is a pressure measurement instrument used to
measure fluid flow velocity. The pitot tube was invented by
the French engineer Henri Pitot in the early 18th century and was modified
to its modern form in the mid-19th century by French scientist Henry
Darcy.
It is widely used to determine the airspeed of an aircraft, water speed of a
boat, and to measure liquid, air and gas velocities in industrial
applications. The pitot tube is used to measure the local velocity at a given
point in the flow stream and not the average velocity in the pipe or
conduit.
12. Working
The basic pitot tube consists of a tube pointing directly into the fluid flow.
As this tube contains fluid, a pressure can be measured; the moving fluid is
brought to rest (stagnates) as there is no outlet to allow flow to continue.
This pressure is the stagnation pressure of the fluid, also known as the total
pressure or (particularly in aviation) the pitot pressure.
The liquid flows up the tube and when equilibrium is attained, the liquid
reaches a height above the free surface of the water stream.
13. Measurement of static pressure in this case is made at the boundary of the
wall (Fig.-1). The axis of the tube measuring the static pressure must be
perpendicular to the boundary and free from burrs, so that the boundary is
smooth and hence the streamlines adjacent to it are not curved. This is done
to sense the static pressure only without any part of the dynamic pressure.
A Pitot tube is also inserted as shown (Fig.-2) to sense the stagnation
pressure. The ends of the Pitot tube, measuring the stagnation pressure, and
the piezometric tube, measuring the static pressure, may be connected to a
suitable differential manometer for the determination of flow velocity and
hence the flow rate.
15. Operations
In industry, the velocities being measured are often those flowing in ducts and
tubing where measurements by an anemometer would be difficult to obtain. In
these kinds of measurements, the most practical instrument to use is the pitot
tube.
The pitot tube can be inserted through a small hole in the duct with the pitot
connected to a U-tube water gauge or some other differential pressure gauge
for determining the velocity inside the ducted wind tunnel. One use of this
technique is to determine the volume of air that is being delivered to a
conditioned space.
