1. Learning Objectives
1. Observe and understand the behaviour of a real fluid flowing over a broad-crested weir,
2. Model this behaviour employing the Continuity and Bernoulli (Energy) Principles to
predict the flow rate from depth measurements.
3. Evaluate these predictions by comparing with measured values and use Specific Energy
to explain the changing nature of the flow over the weir.
2. Introduction
The theory of non-uniform flow in channels is covered by the course text, by many other fluid
mechanics texts, and by several web sites.
The specific energy, E, is the energy at a channel cross-section referred to the base of the
channel (in contrast to the Bernoulli equation, which is referred to a fixed horizontal datum).
The expression given for E is actually an approximation valid for small bed slopes. You've
measured the flume slope, and should examine this approximation in your report. A hydrostatic
pressure distribution is assumed, and you should also examine the validity of this assumption. If
the streamlines are not parallel, then the accelerative forces will modify the pressure - depth
relationship.
In general, two conjugate flows depths satisfy the specific energy equation for a given value of
the specific energy. The greater depth is associated with subcritical flow, and the shallower
depth with supercritical flow. At the critical depth the conjugate depths are equal, and the
discharge for the given specific energy is a maximum.
Broad crested weirs are used as a method of flow measurement in open channel flows. If the
weir is sufficiently high and long, the free surface will drop to critical depth. If the height of
the upstream flow is measured, then the flow rate can be determined.

• Water flume comprising of pump, control valve, venturi and v-notch flow meters,
downstream control gate.
• depth gauges
• 2 vertical water manometers
• 2 total head tubes
4. Preparation
Examine and sketch the layout of the channel and associated flow measuring equipment.
Measure the channel width and note significant geometrical parameters of the nozzle venturi
meter and V-notch weir. Note the directions of readings of all measuring scales.

This is a preliminary text for the chapter. The Oslo Group is invited to provide comments on the
general structure and coverage of the chapter (for example, if it covers the relevant aspects related to
measurement units and conversion factors, and if there are additional topics that should be covered in
this chapter), and on the recommendations to be contained in IRES.
The current text presents the recommendations from the UN Manual F.29 as well as some points that
were raised during the last OG meeting. The issue of “harmonization” of standard/default conversion
factors still needs to be addressed. It was suggested that tables be moved to an annex. Please provide
your views on which ones should be retained in the chapter.

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.

3. -:Introduction
The name of this experiment is pipe Flow. The pur[pose of this lab is to
observe the variation of head loss with velocity for the flow of water through
a small diameter pipe over a range of Reynolds numbers including both
laminar and turbulent flow, and to compare the variation of friction factor
with Reynolds number with published result. This experiment is a
requirement for the fluids laboratory. The experiment was performed by a
group of students.
-:Objective
Determine the pipe friction losses in laminar and turbulent flow. The
purposes of the variation of head loss with velocity for the flow of water
through a small diameter pipe, over a range Reynolds number including both
laminar and turbulent floe, and to compare the variation of friction factor with
Reynolds number with published results.
-:Unit description
The pipe section used is a brass pipe with an inside diameter of 3mm and a
length of 524mm.
The pressure losses are measured in laminar flow with a water manometer.
The statics pressure difference is indicated. In turbulent flow the pressure
difference is measured with a water-filled U-tube manometer. A level tank is
provided to generate the laminar flow. It ensure a constand water in flow
pressure on the pipe section at a constant water level. The level tank is not
used to generate turbulent flow. The water is fed directly from the water main
into the pipe section. The flow rate is set by means of needle valves at each
end of the pipe. The water is supplied either from the hydraulic bench or from
the laboratory main. An enclosed water circuit can be established with the
hydraulic bench.
