Introduction
This experiment introduces you to orifice obstruction meters, which are a common tool used
to measure fluid flow rate. The experimental system includes two types of orifice obstruction
meters: flow nozzles and orifice plates. The differential pressure across the orifice obstruction
meter is needed to calculate flow rate, and so pressure measuring devices are included to
measure a) the differential pressure across the flow nozzle and b) the differential pressure across
the orifice plate. Figure 1 illustrates the experimental system and its relevant components.
Air from the room enters the plenum chamber through the nozzle. The air then flows through
flexible black tubing and into a transparent circular duct that is instrumented with the orifice
plate. Lastly the air flow enters the vacuum pump via more flexible black tubing and is returned
to the room via the vacuum pumps outlet. Variable air flow through the system can be achieved
by a rheostat knob that controls the vacuum pump. We will assume that any leaks in the system
are negligible. Since the obstruction meters are connected in series, both obstruction meters
measure the same mass flow rate (i.e. conservation of mass).
In the case of the flow nozzles, two different sizes are provided. Both nozzles are
standardized ASME long-radius flow nozzles with diameters of 1.265 cm and 2.530 cm for the
small and medium nozzles, respectively. The orifice plate has a diameter of 0.795 in and is
located in a pipe with a diameter of 2 in.

part A of this lab
The discharge coefficient, CD, is a very important performance parameter for an orifice
obstruction meter. The discharge coefficient tells you the ratio of the actual orifice flow rate,
Qactual, to the ideal orifice flow rate, Qideal:
𝐶! =
!!"#$!%
!!"#$%
[1]
The ideal flow rate corresponds to the flow rate as derived from Bernoulli’s equation. Two of
the assumptions that Bernoulli’s equation makes are isentropic and incompressible flow. While
these are good approximations in many engineering situations, no real system is every truly
isentropic and incompressible. Hence the discharge coefficient is always less than 1. In this lab
you will determine the discharge coefficient for the nozzles as well as the orifice plate.
Procedure
• With the small nozzle measure at five different steady-state (i.e. make sure pressures are
not changing with time) flow rates measure:
o The differential pressure across the flow nozzle.
o The differential pressure across the orifice plate wi ..

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

VENTURIMETER -Application of Bernoulli's LawKundan Kumar
A venturimeter is essentially a short pipe consisting of two conical parts with a short portion of uniform cross-section in between. This short portion has the minimum area and is known as the throat. The two conical portions have the same base diameter, but one is having a shorter length with a larger cone angle while the other is having a larger length with a smaller cone angle.

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.

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Experiment No. 2
Experiment Name : - VENTURI METER
Objectives
To measure the discharge and to investigate the characteristic of a Venturi
Meter.
Introduction
Flow meters are used in the industry to measure the volumetric flow rate of
fluids. Differential pressure type flow meters ( Head flow meters)measure flow
rate by introducing a constriction in the flow. The pressure difference caused
by the constriction is correlated to the flow rate using Bernoulli's theorem. If a
constriction is placed in a pipe carrying a stream of fuid,there will be an
increase in velocity,and hence an increase in kinetic energy ,at the point of
constriction.From an energy balance as given by Bernoulli’s theorem,there
must be a corresponding reduction in pressure.Rate of discharge from the
constriction can be calculated by knowing this pressure reduction,the area
available for flow at the constriction ,the density of the fluid and the
coefficient of discharge Cd. Coefficient of discharge is the ratio of actual flow
to the theoretical flow and makes allowances for stream contraction and
frictional effects. Venturi meter, orifice meter, and Pitot tube are widely used
head flow meters in the industry. The Pitotstatic is often used for measuring
the local velocity in pipes or ducts. For measuring flow in enclosed ducts or
channels

Theory
Consider the flow of an incompressible fluid through the convergent-divergent
pipe shown in Fig.2. The cross-sectional area at the upstream section 1 is a1, at
the throat section 2 is a2, and at any other arbitrary section n is an. Piezometer
tubes at these sections register h1, h2, and hn as shown.
Assuming that there is no loss of energy along the pipe, and that the velocity and piezometric
heads are constant across each of the sections considered, then Bernoulli’s theorem states that
(P1/ρg) + (v1 /2g) + z = (P /ρg) + (v /2g) + z 2

Procedure
• The apparatus is located on the flat top of the hydraulic bench and the
instrument is properly levelled with the help of spirit level. • The water is
allowed to fill in the manometer tubes until all trapped air is removed • All
manometer tubes are checked properly connected to the corresponding
pressure taps are air-bubble free • The discharged valve is adjusted to a high
measureable flow rate. • After the level is stabilized, the water flow rate is
measured using volumetric method. • The pressure head for each point(total
six) is observed by the reading shown in monometer tube similarly the total
head at each point is observed with the help of hypodermic probe

Discussion:-
One of the disadvantages of orifice meters is the large irreversible pressure
loss across the orifice, which results in substantial pumping costs in case of
large diameter pipes. However, the same principle can be exploited with only
minimal pressure loss with the use of a Venture meter. In this case, the meter
consists of a section with both a smooth contraction and a smooth expansion.
