Pumps are machines that transfer fluids by mechanically adding energy to them. There are two main types: centrifugal and positive displacement. Centrifugal pumps use centrifugal force to push liquid outwards from the center, while positive displacement pumps have mechanisms like lobes, gears or diaphragms that push discrete volumes of liquid out of the pump. Centrifugal pumps are generally used for high flow, low pressure applications while positive displacement pumps are used for low flow, high pressure applications or high viscosity liquids. Major components of centrifugal pumps include an impeller, casing, shaft and seals, while positive displacement pumps have components like lobes or gears that expand and contract pump chambers.
in industries like iron and glass the fluid for hydraulic machines are delivered by multistage pumps. this is the basic introduction for clearing the concept of multi stage pumps.
Basics Fundamentals and working Principle of Centrifugal Pump.SHASHI BHUSHAN
Basics Fundamentals and working Principle of Centrifugal Pump. Centrifugal pumps are the rotodynamic machines that convert mechanical energy of shaft into kinetic and pressure energy of Fluid which may be used to raise the level of fluid. A centrifugal pump is named so, because the energy added by the impeller to the fluid is largely due to centrifugal effects.

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.

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!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Basic Terms
• Volumetric Flow rate: Flow rate /Capacity of a pump is the amount of
liquid delivered by the pump per unit of time (m3/hr).
• Total Head: It is term that defines
how high the pump can lift a liquid./Pressure in
terms of height.
• Hydraulic Power: Power transferred
by the pump to the liquid.
• VACUUM: Pressure lower than the atmospheric pressure.
3. Definition
• Pump: When a fluid has to be "moved" in a system, pumps are used. The
pump is a machine which has the function of increasing the total energy of
a liquid; this means that the pump transfers energy to the fluid that it
receives from the driving motor”.
Need Of a Pump:
Used to pump a liquid from lower pressure area to a High pressure area.
To increase Flow rate.
To move liquid from lower elevation to higher elevation.
5. Principle of Operation
• Dynamic Pump: . In dynamic pumps, energy is added to the fluid
continuously through the rotary motion of the blades. This increase in
energy is converted to a gain in Pressure Energy when the liquid is allowed
to pass through an increased area.
6. Centrifugal Pump
• Working Principle:
Works on the principle of centrifugal force. This is the force that pushes the liquid away from
the centre(in tangential direction).
Converting Prime Mover energy into Mechanical energy
through shaft .
Converting Mechanical energy into fluid energy
impeller.
Converting kinetic Energy into pressure
energy through the volute casing.
7. Centrifugal Pump
• Major Parts:
• Shaft: It transmit the torque/Power. and supporting the impeller and
other rotating parts. Shaft is protected from erosion ,corrosion and wear
at the seal chamber through renewable sleeve.
• Impeller: An Impeller has vanes that pushes the liquid through the
impeller. Transmit energy into the fluid (hydraulic energy).
• Volute/Casing: Impeller are fitted inside the casing. Volute casing
is a curved shaped ,increasing in cross sectional area. Volute
reduces the velocity of the liquid and increases the pressure.
13. • Radial Pumps: High Pressure& For low flow rate/Centrifugal pump.
• Axial Pumps: Axial-flow pumps operate at much lower pressures and higher flow
rates than radial-flow pumps.
• Mixed Flow Pumps: Mixed-flow pumps operate at higher pressures than axial-
flow pumps while delivering higher discharges than radial-flow pumps.
14. • Why Centrifugal Pumps Need Priming?
Centrifugal pumps does not create suction at the start without impeller filled
with water. Hence Priming required . Priming is the process in which the
impeller of a centrifugal pump will get fully sub merged in liquid without any air
trap inside. This is especially required when there is a first start up. But it is
advisable to start the pump only after primping.
15. Multistage Centrifugal Pumps.
In order to achieve a higher discharge pressure multiple impellers are used
within a single pump. Depending upon the requirement.
• `
17. Positive Displacement Pumps
• Working Principle: Positive Displacement Pump has an expanding
cavity on the suction side of the pump and a decreasing cavity on the
discharge side. Liquid is allowed to flow into the pump as the cavity on the
suction side expands and the liquid is forced out of the discharge as the
cavity collapses.
22. Displacement Vs Centrifugal
• Centrifugal pumps are suitable for low head and high flow rate.
• PD pumps produce high head and low flow rate.
• PD are suitable for High Viscosity application.
• Centrifugal Pumps are not recommended for high viscosity application
because as viscosity increases its flow deceases.
• Usually a relieve valve is attached with the displacement pumps.
23. Related Terminologies
Cavitation: It is the process in which bubbles are formed due to sufficient
Pressure drop at the suction of the pump.
Bubble Formation inside a pump.
Growth of bubbles.
Collapse of bubble.

Produces shock waves.
