Francis turbines operate under medium heads of water and quantities of flow. The water enters the circumference of the runner and travels toward the center axis, exiting axially along the shaft. The main components are the penstock, scroll casing, guide mechanism, runner and runner vanes, and draft tube. Water flows through the penstock and spiral casing, where some potential energy is converted to kinetic energy. It then flows through guide vanes and is directed radially inward toward the runner's outer diameter. The water moves over the runner's moving blades radially and exits through the draft tube, with the remaining potential energy converted to kinetic energy acting as a reaction force on the runner.

Hydraulic turbines can be classified in several ways:
1) Based on flow path - axial flow, radial flow, or mixed flow turbines depending on whether water flows parallel, perpendicular, or with components of both to the axis of rotation.
2) Based on pressure change - impulse turbines where pressure doesn't change through the rotor, and reaction turbines where pressure changes through the rotor.
3) Based on head and specific speed - high, medium, low head turbines and low, medium, high specific speed turbines.
The document then provides details on the classification, parts, and working of Pelton and Francis turbines as examples of impulse and reaction turbines.
Small hydro
Hydraulic turbines convert the kinetic energy of flowing water into mechanical energy by passing water through blades attached to a rotating shaft. There are several types of hydraulic turbines classified based on flow path (axial, radial, mixed), pressure change (impulse, reaction), head (high, medium, low), and speed. Examples include Pelton wheels, Francis turbines, and Kaplan turbines. All hydraulic turbines work to convert the pressure and kinetic energy of flowing water into rotational energy to drive generators and produce electricity at hydroelectric power plants.
Turbine and pump.pptx
Md Toukir Shah prepared a document about turbines and pumps. It defines turbines as devices that convert kinetic energy from fluids like water or steam into rotational motion. Turbines are classified as impulse or reaction turbines based on how the fluid acts on the moving blades. Impulse turbines like the Pelton wheel use jets of fluid to directly strike and spin the blades, while reaction turbines like the Francis turbine spin due to pressure changes on the fixed and moving blades. Key components of turbines include the casing, nozzles, buckets/blades, and draft tubes.
Francis Turbine
The Francis turbine is a mixed-flow reaction turbine that was developed by James B. Francis in 1849. It operates in a water head from 60 to 250 meters. Water enters the runner radially at the outer periphery and exits axially at the center. It uses both the kinetic and pressure energy of water to drive the turbine. Key components include a spiral casing, stay vanes, guide vanes, runner blades, and a draft tube. The guide vanes direct water onto the runner blades to efficiently convert the hydraulic energy of water into mechanical rotation of the shaft and electrical energy via a generator. The speed of the turbine is maintained constant via a governing mechanism that controls the guide vanes.
Hydraulic Turbine & its Types
This document discusses different types of hydraulic turbines used to convert hydraulic energy from flowing water into electrical energy. It describes the main components and operating principles of Pelton, Francis, and Kaplan turbines. Pelton turbines use jet impacts to rotate an impulse wheel, while Francis and Kaplan turbines are reaction turbines where water pressure decreases as it flows through the runner blades. Francis turbines use mixed radial-axial flow and are widely used over a range of heads. Kaplan turbines have propeller-like adjustable blades for axial flow and are best for low heads with large flows. Draft tubes and governing systems are also discussed.

Turbines convert hydraulic energy from flowing water into mechanical energy via a shaft. Francis turbines, invented in 1848, are a common type of inward reaction turbine that convert both kinetic and pressure energy.

Pelton wheels are impulse turbines that use nozzles to convert water's pressure energy into kinetic energy before it strikes buckets on the runner to rotate it. They are suitable for high head applications.
Steam turbine and its types
This document discusses the Rankine cycle, which is a thermodynamic cycle derived from the Carnot vapor power cycle. It consists of four processes: 1) Isobaric heat supply in the boiler where water is heated to high pressure steam, 2) Adiabatic expansion of the steam in a turbine to produce work, 3) Isobaric heat rejection in the condenser where the steam is condensed back to water, and 4) Adiabatic pumping of the condensate back to the boiler to complete the cycle. The heat and work transfers are also defined for each process.

A Strategic Approach: GenAI in Education
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

Francis Turbine Francis Turbine Francis Turbine • A Francis turbine is a mixed flow turbine in which the water enters at the circumference of the runner and travels towards the axis of the runner. Finally, it comes out axially along the shaft. • It operates under medium heads and requires medium quantity of flow. • The water through the guide vanes and then through runner vanes, transferring its energy to the runner. • Finally, the water is discharged into the tailrace through a draft tube.

- 5. PENSTOCK - It is the waterway used to carry the water from the reservoir to the turbine SCROLL CASING - It is the casing around the turbine wheel and it evenly distributes the water around the circumference of the wheel. GUIDE MECHANISM- This reaction is connected to the turbine component spiral casing. Material for the guide vanes is usually cast steel. RUNNER AND RUNNER VANES- It is a circular wheel on which a series of curved blades are fixed.Made of iron or stainless steel
- 6. In operation, water from the reservoir (dam) flows through the penstock and enters the spiral casing. As the water flows through the tapped spiral casing a part of its potential energy is converted into kinetic energy. Water flows through the guide blades, gets deflected and then flows radially inwards to the outer diameter of the runner. The water then moves over the moving blades in the radial direction and is finally discharged to the tailrace axially from the centre of runner through a draft tube.
- 7. During its flow over the runner blades, the blade passages acts as nozzle ,and the remaining parts of potential energy is converted into kinetic energy. Here, the jet of water does not have an effect on the runner ,they are leaving the runner at high velocity. Since the water leaves the blades at high velocity, there is a reaction force on the runner. This force sets the runner into rotatory motion. Hence the shaft connected to the runner also rotates there by doing useful work.The shaft in turn drives the generator to produce electricity.
