The Otto cycle describes the thermodynamic processes that occur in a 4-stroke internal combustion engine. It consists of four stages: intake, compression, combustion (power), and exhaust. In the intake stroke, air-fuel mixture enters the cylinder. In compression, the mixture is compressed. In combustion, ignition causes the mixture to burn, expanding and producing power. In exhaust, burned gases are pushed out of the cylinder. The Otto cycle forms a closed loop on a pressure-volume diagram, with the area inside representing the work produced by the engine in each cycle.

2. There are four regimes of pool boiling as excess temperature increases: natural convection, nucleate boiling, transition boiling, and film boiling. In nucleate boiling, bubbles form rapidly at nucleation sites on the surface.
3. The pool boiling curve graphs heat flux against the temperature excess of a surface above the liquid's boiling point. It shows regions of unstable and stable boiling across the different boiling regimes.

A steam turbine is a prime mover in which the potential energy of the steam is transformed into kinetic energy and later in its turn is transformed into the mechanical energy of rotation of the turbine shaftHydraulic Machines Fluid coupling, Fluid torque converter
This document discusses hydraulic machines, specifically fluid couplings and fluid torque converters. It describes how fluid couplings work by using a pump impeller and turbine runner to transfer rotational energy between two shafts without a direct mechanical connection. The driven shaft speed is typically 2-4% lower than the driving shaft due to losses. Fluid couplings are 98% efficient and isolate vibrations. Fluid torque converters build on this design by adding a stationary reaction member, allowing variable torque transfer between shafts. They are commonly used in automatic transmissions for vehicles, marine propulsion, industrial machinery, and locomotives.

air standard, fuel air and actual cycles
The document discusses various factors that affect the efficiency of internal combustion engines such as specific heat, dissociation, premixed vs non-premixed fuel charges, and different types of losses in actual engine cycles compared to ideal cycles. It notes that the actual efficiency of a good engine is around 25% of the estimated efficiency from the ideal air standard cycle due to losses from factors like heat transfer, combustion, pumping, and blow-by. Fuel-air ratio can impact maximum power output due to chemical equilibrium losses. Variable specific heats can increase maximum pressure but decrease maximum temperature compared to constant specific heats.
rankine cycle
This document presents information on the Rankine cycle. It contains the following key points:
1. The Rankine cycle converts heat into work through a closed loop that uses water as the working fluid. It generates about 90% of the world's electric power.
2. An ideal Rankine cycle involves isothermal and isobaric processes, while a real cycle involves non-reversible and isentropic compression and expansion.
3. Variations like the reheat cycle and regeneration cycle can improve the efficiency by reheating steam before the turbine or preheating feedwater, but increase costs.
Rankine cycle
The document summarizes the ideal Rankine cycle process. It describes 4 key processes:
1) Constant pressure heating of water to steam in the boiler.
2) Reversible, adiabatic expansion of steam in the turbine.
3) Reversible heat rejection during condensation of steam in the condenser.
4) Reversible, adiabatic compression of the liquid in the pump back to the boiler pressure.
It notes that real processes are irreversible with entropy increases due to friction and heat transfer, reducing turbine work and efficiency. Losses occur in the turbine, condenser, pump and via piping. Superheating improves efficiency but is limited by material temperatures.
centrifugal compressors overview
Centrifugal compressors work by imparting kinetic energy to a gas stream using an impeller, converting the dynamic energy into increased static pressure. They have advantages like high throughput capacity and efficiency over a wide operating range, but also disadvantages like discharge pressure limitations. Key components include impellers, diffusers, volutes, casings, shafts, bearings, and seals. Surge, a dangerous condition where flow reverses rapidly, must be controlled. Compressors can operate alone or in multi-stage arrangements with intercoolers. Common drivers are steam turbines, electric motors, and gas turbines.
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.
Rankine cycle
The document describes the Rankine cycle, which is a vapor power cycle that can be practically implemented. It discusses the ideal Rankine cycle process of:
1. Isentropic compression in a pump
2. Constant pressure heat addition in a boiler
3. Isentropic expansion in a turbine
4. Constant pressure heat rejection in a condenser
It also discusses deviations from the ideal cycle, such as non-ideal pump and turbine efficiencies. Methods to increase cycle efficiency include lowering the condenser pressure, increasing steam superheating, and raising the boiler pressure. Advanced cycles like reheat and regeneration are also mentioned to further improve performance.
The reheat cycle
This document discusses the reheat cycle in thermodynamics. The reheat cycle is a modification of the Rankine cycle that is used in steam power plants. It works by reheating the steam after it expands in the high-pressure turbine and before it expands further in the low-pressure turbine. This increases the efficiency by raising the mean temperature of heat addition and reducing moisture content in the steam. Reheating allows for higher turbine work extraction and thermal efficiency compared to the basic Rankine cycle. The document examines the working of reheat cycles in steam turbines and thermal power plants, and their advantages in improving efficiency and reducing blade erosion.
Gas turbines
Gas turbines have three main parts - an air compressor, combustion chamber, and turbine. The air compressor increases the pressure of air that is mixed with fuel in the combustion chamber and ignited. This powers the turbine, which can generate mechanical power or thrust. There are two main types - open cycle gas turbines that exhaust air to the atmosphere, and closed cycle gas turbines that recirculate the working fluid through a cooler before returning it to the compressor. Methods to improve gas turbine efficiency include intercooling the compressed air between compression stages, reheating the gas before a secondary expansion turbine, and regenerating heat from the exhaust to preheat the incoming compressed air.
Fectors Affecting the efficiency of Rankine cycle
This document discusses three thermodynamic variables that affect the efficiency and work output of a Rankine cycle: (1) superheating of steam, (2) boiler pressure, and (3) exhaust steam pressure. Superheating steam increases efficiency by raising the average heat addition temperature while keeping the average heat rejection temperature the same. Increasing boiler pressure raises net work and lowers heat rejected, improving efficiency. Reducing condenser pressure raises net work and efficiency by lowering the average heat rejection temperature.
Day 3: Fans and Pumps

The document also provides examples and case studies to illustrate fan performance analysis and potential efficiency improvements.

The document then covers the history, basic components and operation of gas turbine power plants. It distinguishes between open cycle and closed cycle gas turbine power plants and discusses their diagrams. The document concludes by covering fuel types, advantages, disadvantages and applications of gas turbine power plants.

Managerial Hubris | Finance
The document discusses the concept of managerial hubris, which refers to excessive pride or self-confidence held by senior managers that can lead to cognitive biases and poor decision making. Managerial hubris can result in empire building within an organization as managers seek to expand their power and influence. It is also related to mergers and acquisitions if acquiring company managers overestimate their ability to manage target companies. This can lead to winners' curse, where the winning bid exceeds the true value of the target. The hubris hypothesis suggests managerial hubris in acquisitions can result in bids over the intrinsic value and ultimately lower shareholder returns.

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.
