A hydraulic machine transfers mechanical energy between a liquid flowing through it and its operating member (such as a runner or piston). Turbines and pumps are two types of hydraulic machines. Turbines can be classified according to the type of energy at their inlet (impulse or reaction), the direction of fluid flow through the runner (tangential, radial, axial, or mixed), or the head of water at their inlet (high, medium, or low head). They can also be classified based on their specific speed, which is a measure of the speed a geometrically similar turbine would operate at to produce unit power under unit head. Common examples of turbines that fall under each classification are provided.

Selection of Turbine With Respect to Head VS Specific Speed
The document discusses the selection of turbines based on head and specific speed. It defines turbines as devices that extract energy from fluid and describes the main types as impulse and reaction turbines. Impulse turbines use velocity to move the runner while reaction turbines develop power from pressure and moving fluid. Turbines are selected based on the specific conditions like head and flow. High head turbines operate over 250m head with low flow. Francis turbines are used for medium heads from 45-250m. Kaplan turbines are suitable for low heads under 45m with high flow. Specific speed is also used to select turbines, with low specific speed turbines like Pelton used for high heads and high specific speed propeller turbines for low heads.
Selection of Turbine | Fluid Mechanics
This document provides a comparison of different types of hydraulic turbines and considerations for selecting the appropriate turbine for a hydroelectric power plant. It compares Pelton, Francis, and Kaplan turbines based on criteria such as head, discharge required, efficiency, and more. The key points for selection include considering the specific speed to match the generator speed, choosing the turbine with the highest efficiency, ability to operate at part loads, available head and fluctuations, and shaft orientation. The turbines are recommended for different head ranges, with Pelton used for very high heads and Kaplan for heads below 30 meters.
Centrifugal Pumps
This document discusses centrifugal pumps, including their basic principles, classification, components, and potential issues. Centrifugal pumps work by imparting a whirling motion to liquid using a rotating impeller with backward curved vanes, forcing the liquid to move from the center to the outer edge and discharge from the casing. Pumps can be classified based on the number of impellers, shaft disposition, or developed head. Cavitation, where bubbles form and implode inside pumps, can cause damage and should be avoided by ensuring the net positive suction head available exceeds the required level.
Centrifugal Pumps
Centrifugal pumps are rotodynamic pumps that use a rotating impeller to increase the pressure of a liquid. The impeller spins and throws liquid outward via centrifugal force, increasing pressure. Key parts include the impeller, casing, suction and delivery pipes. Centrifugal pumps are classified based on impeller shape, working head, number of stages, flow direction, and number of suctions. They work by converting the kinetic energy of the liquid into pressure energy. The minimum speed required for startup depends on the manometric head. Cavitation can occur if the pressure drops below vapor pressure, forming bubbles that collapse and damage surfaces.
Centrifugal pump
The document discusses centrifugal pumps. It describes how centrifugal pumps work by converting mechanical energy to hydraulic energy using centrifugal force. They work on the principle of forced vortex flow. Key components include an impeller that rotates and accelerates the fluid outward, and a casing that captures the fluid and converts its kinetic energy to pressure. Centrifugal pumps are used to pump liquids like water, sewage, petroleum and more. Performance curves are used to predict pump behavior under different operating conditions.
detail study of kaplan turbine
The Kaplan turbine is a water turbine that was invented in 1913-1922 by Viktor Kaplan. It has adjustable blades that allow it to efficiently handle a wide variation of water flows. The Kaplan turbine is well-suited for low head sites between 2-40 meters and has efficiencies over 90%. It is an inward flow reaction turbine where the water changes pressure and gives up energy as it moves through the adjustable blades, causing the runner to spin. The Kaplan turbine's adjustable blades make it more efficient at partial loads compared to other water turbines.
Centrifugal pump
This document discusses centrifugal pumps. It begins by defining pumps and their purpose of increasing fluid velocity, pressure, or elevation. It then classifies centrifugal pumps and describes their operation of converting motor energy into kinetic and potential energy of fluid flow using a rotating impeller. The key parts of centrifugal pumps are identified as the impeller, casing, suction pump, and discharge pump. The working principle is explained as fluid being accelerated outward by centrifugal force when the impeller rotates. Centrifugal pumps are commonly used for water supply, industry, and domestic applications due to their simplicity, low cost, and efficiency.

The document discusses specific speed, which is a metric used to compare different types of turbines. Specific speed is defined as the speed of a geometrically similar turbine that produces 1 unit of power under 1 unit of head. The specific speed ranges are provided for common turbine types: Pelton wheel turbines have a specific speed of 80-50, Francis turbines range from 50-250, and Kaplan turbines have the highest specific speed range of 250-850. Specific speed is one factor used to select the appropriate turbine type for installation based on factors like head, part load operations, number of units, cost, and more. Turbines are also classified as having high, medium, or low specific speeds based on these defined ranges.
Hydro turbines
This presentation summarizes different types of hydro turbines classified based on how water acts on the turbine blades. Impulse turbines like Pelton and Turgo turbines use the kinetic energy of a high velocity water jet to turn the runner. Reaction turbines like Francis and Kaplan turbines use both the pressure and velocity of water. Francis turbines have fixed blades while Kaplan turbines have adjustable blades controlled by a servo mechanism. The presentation provides details on the working, typical specifications and applications of these common hydro turbine types to help select the optimal turbine for a hydroelectric project based on factors like head, flow, and output requirements.

Hydraulic turbines are machines which convert hydraulic energy into mechanical energy. If the machine transforms mechanical energy into hydraulic energy it is called a pump. Thus in turbines, fluid does work on the machine and machine produces power. but, the pump absorbs the power and work is done on the fluid.

Jet propulsion means the propulsion or movement of the bodies such as ships, aircrafts, rocket etc. with the help of jet.
It is well known from Newton’s Law that to change momentum of fluid, a force is required. Similarly, when momentum of fluid is changed, a force is generated. This principle is made use in hydraulic turbine.
Hydraulic turbines
Hydraulic turbines use the energy of flowing water to rotate a runner wheel and convert the energy into mechanical rotation. They are classified in several ways:
1. Based on the hydraulic action - Impulse turbines convert water's kinetic energy before striking the runner, while reaction turbines use both pressure and kinetic energy.
2. Based on flow direction - Radial flow turbines have inward or outward flow, axial flow is parallel to rotation, and tangential flow strikes the runner tangentially.
3. Based on head and flow - High, medium, low, and very low head turbines include Pelton, Francis, Kaplan, and propeller turbines respectively.

There are two main types: hydraulic turbines, where the rotating component receives energy from the liquid flow; and pumps, where energy is transferred from the rotating component to the liquid. Common hydraulic turbines include impulse turbines like the Pelton wheel, which use jet momentum changes, and reaction turbines like the Francis turbine, where pressure and kinetic energy changes drive the rotating runner. Turbines are classified based on factors such as the type of energy used, direction of liquid flow, operating head, and specific speed. Hydraulic power plants typically include a dam, penstock, water turbine, and tailrace to harness potential and kinetic energy of water
Turbines
Turbines can be classified in several ways:
- By head and quantity of water as high, medium, or low head turbines
- By hydraulic action as impulse or reaction turbines
- By direction of water flow in the runner as tangential, radial, axial, or mixed flow
- By specific speed which is defined for Pelton, Francis, and Kaplan turbines
- By disposition of the shaft as horizontal for Pelton and vertical for others

STEAM AND GAS TURBINES ppt
Turbines can be either impulse or reaction turbines. Impulse turbines use nozzles to direct steam onto curved blades with a bucket-like shape, extracting energy from the steam's kinetic energy. Reaction turbines have fixed and moving blades, with the fixed blades acting as nozzles to increase the steam's velocity before it passes over the moving blades. Common impulse turbines include Pelton wheels, while common reaction turbines are Francis and Kaplan turbines. Turbines are highly efficient machines that convert the energy in fluids like steam or water into useful rotational work, and they are widely used in applications like power generation, ships, aircraft, and pumps.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
A review on techniques and modelling methodologies used for checking electrom...
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
