This document provides an overview of fluid power systems, including hydraulics and pneumatics. It discusses the basic components of fluid power systems, such as pumps, valves, actuators and piping. Examples are given of common hydraulic systems, like vehicle brakes and power steering. Advantages of fluid power include easy control and force multiplication. The document also compares hydraulic, pneumatic and electrical systems for lifting a load.
FLUID MECHANICS
Fluid mechanics is the branch of physics which involves the study of fluids (liquids, gases, and plasmas) and the forces on them. Fluid mechanics can be divided into fluid statics, the study of fluids at rest; and fluid dynamics, the study of the effect of forces on fluid motion. It is a branch of continuum mechanics, a subject which models matter without using the information that it is made out of atoms; that is, it models matter from a macroscopic viewpoint rather than from microscopic. Fluid mechanics, especially fluid dynamics, is an active field of research with many problems that are partly or wholly unsolved. Fluid mechanics can be mathematically complex, and can best be solved by numerical methods, typically using computers. A modern discipline, calledcomputational fluid dynamics (CFD), is devoted to this approach to solving fluid mechanics problems. Particle image velocimetry, an experimental method for visualizing and analyzing fluid flow, also takes advantage of the highly visual nature of fluid flow.
The study of fluid mechanics goes back at least to the days of ancient Greece, when Archimedes investigated fluid statics and buoyancy and formulated his famous law known now as the Archimedes' principle, which was published in his work On Floating Bodies - generally considered to be the first major work on fluid mechanics. Rapid advancement in fluid mechanics began with Leonardo da Vinci (observations and experiments), Evangelista Torricelli (invented the barometer), Isaac Newton (investigated viscosity) and Blaise Pascal (researched hydrostatics, formulated Pascal's law), and was continued by Daniel Bernoulli with the introduction of mathematical fluid dynamics in Hydrodynamica .
Fluid statics or hydrostatics is the branch of fluid mechanics that studies fluids at rest. It embraces the study of the conditions under which fluids are at rest in stableequilibrium; and is contrasted with fluid dynamics, the study of fluids in motion.
• the dynamics of fluids are the foundation of the understanding of water movement in streams and in the subsurface
• we need to understand this in order to figure out how to measure river discharge, for example
• the basic principles also apply to the flow of air, lava, glaciers, and the Earth's mantle
• we usually classify matter as either solid, liquid, or gas, based on macroscopic properties
o a gas takes on the shape and volume of a container,
o a liquid takes the shape of the portion of the container that it fills but retains a fixed volume
o a solid has its own defined shape as well as volume
• liquids and gases are called fluids
• shear stress is a tangential force per unit area acting on a surface
The document discusses the brake system used in vehicles. It defines a brake as a device that inhibits motion using friction to convert kinetic energy into heat. Brakes slow or stop a vehicle using friction between stationary and moving parts, with some regenerative brakes converting energy to electricity. The document classifies brakes based on actuation method (foot, hand), operation type (mechanical, hydraulic, air, vacuum), location (front, rear wheels), and application method (internally expanding, externally contracting). Hydraulic brakes are most common, using pressurized brake fluid and Pascal's law to generate equal braking force on all wheels.
The document discusses brake hydraulic theory and the operation of automotive brake systems. It explains that brake systems use hydraulic principles to transmit mechanical force from the brake pedal to the brakes through pressurized brake fluid. The key components that allow this include the master cylinder, power boosters, lines and hoses, control valves, and disc or drum brakes. Control valves help proportion braking force to each wheel for stability and to prevent locking during heavy braking.
This document provides an overview of fundamentals of hydraulic systems. It begins by listing the chapter learning objectives for skills and knowledge related to hydraulic systems. It then defines key terms like flow, pressure, pumps, actuators, and others. It describes Pascal's law of hydraulic pressure transmission and gives examples. It explains how hydraulic systems provide force multiplication and gives advantages like precise control, flexibility, and disadvantages like potential leaks and cleanliness requirements. Bernoulli's principle of fluid dynamics is also mentioned. Safety organizations and concerns unique to hydraulic systems are covered at the end.
This document is a project report submitted by Ajay Yadav for the partial fulfillment of a Bachelor of Technology degree. The project focuses on developing an electromagnetic brake system as an alternative to conventional friction brakes. It provides an introduction to brake systems, describes how ordinary friction brakes work, and discusses some of their limitations like brake fading from heat buildup. The report then outlines the key components and working principle of the proposed electromagnetic brake, which uses electromagnetic force rather than friction to slow or stop motion.
Hydraulics uses pressurized fluids to transmit force efficiently from one location to another on an aircraft. It has several advantages over other transmission systems including high efficiency, dependability, sensitivity of control, flexibility of installation in confined spaces, low weight requirements, and self-lubrication. Hydraulics is used on Army aircraft to operate systems like landing gear, brakes, flaps, flight controls, and various actuators.
The document discusses various types of braking systems used in automobiles, including mechanical brakes, hydraulic brakes, power brakes, drum brakes, and disc brakes. It provides details on the components and working of hydraulic braking systems, drum brakes, and disc brakes through diagrams. The document also discusses regenerative braking, anti-lock braking systems, and describes power brakes and notes the types used including air brakes, air-hydraulic brakes, vacuum brakes, and electric brakes.
This document discusses fluid mechanics and its applications in various engineering systems. It begins by defining fluids and their properties such as being shapeless and transmitting pressure equally in all directions. It then discusses the two main types of fluids - hydraulic and pneumatic - and provides examples. Applications of fluid mechanics principles like Pascal's principle and Archimedes' principle are explained. Case studies on braking systems, lifting devices and aeronautical engineering are provided to illustrate how these principles are applied. Hydraulic and pneumatic systems for brakes in vehicles and trains are described. Innovation in ABS braking systems is also covered.
This document discusses the use of Sesam Marine software to simulate marine operations such as offshore installations. It provides an overview of the software's capabilities, including defining objects and bodies, couplings such as fenders and docking cones, conditions, and post-processing of results. The document also presents examples of applications like liftline analysis, float-over installations, and module placements. A live demo is planned to illustrate simulation of subsea structure installation and float-over processes.

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Observability Concepts EVERY Developer Should Know -- DeveloperWeek Europe.pdfPaige Cruz
Monitoring and observability aren’t traditionally found in software curriculums and many of us cobble this knowledge together from whatever vendor or ecosystem we were first introduced to and whatever is a part of your current company’s observability stack.
While the dev and ops silo continues to crumble….many organizations still relegate monitoring & observability as the purview of ops, infra and SRE teams. This is a mistake - achieving a highly observable system requires collaboration up and down the stack.
I, a former op, would like to extend an invitation to all application developers to join the observability party will share these foundational concepts to build on:

Definition of a fluid
A continuous, amorphous substance whose molecules move
freely past one another and that has the tendency to
assume the shape of its container; a liquid or gas.
http://www.thefreedictionary.com/fluid
Properties of fluids
• Unable to support shear stresses
• Take on the shape of the container

Principles of Fluid Mechanics
• Hydrostatic pressure
• Pressure Principle
• Archimedes' Principles

4. Fluid Mechanics and Braking Systems 27/5/12
Hydrostatic Pressure
• When an object placed in a fluid, the fluid exerts a pressure over the entire surface of the
object
• The pressure acts at 90o to the surface of the object at any point
Pressure, P (Pa) = F = Force (N)
A Area (m2)

5. Fluid Mechanics and Braking Systems 27/5/12
Hydrostatic Pressure and Depth
Rule: The deeper an object is submerged, the greater the hydrostatic pressure
Hydrostatic Pressure Depth Relationship
Given the pressure at the surface, Po (in Pa), the pressure (in Pa) at depth, h ( in m) is:
P = Po + ρgh
where
-3
ρ = density of the fluid (a constant - kgm )
-2
g = acceleration due to gravity (ms )

Pascal's Principle
• Pressure applied to an enclosed liquid is transmitted undiminished to every point
in the fluid and to the walls of the container
• Commonly used in sealed hydraulic systems, e.g. automotive braking systems

Archimedes Principle
• When immersed in water an object will weigh less
than in air
• Water provides an upward force (buoyancy) that
partially counteracts the weight force
• If the upward force by the water on an object is
greater than the weight force, the object floats
Factors that effect buoyancy
• The density of the fluid
• The volume of the submerged object
10
11. Fluid Mechanics and Braking Systems 27/5/12
As Archimedes put it ....
A body wholly or partially
submerged in a fluid is buoyed up
This is independent of the
by a force equal to the weight of
composition or shape of the
the fluid displaced by the body
object

Specific Gravity
Using Archimedes Principle, an object's specific gravity can be
calculated
Specific Gravity = Weight of object in air
Weight of object when submerged in water

Brakes used on Trains
• The braking systems on trains are based on a different "fluid" - namely
compressed air
• In 1869, George Westinghouse developed a braking system that used compressed
air to hold the brake shoe off the wheels of the carriages
• To apply the brake the air is released, (or the pressure fails), and the bakes are
immediately activated
• The method of braking is used with trains as a safety feature and is still used
today

Innovation in Braking Systems - ABS or Anti-lock
Braking System
Why was it developed?
• When a vehicle brakes suddenly, the wheels typically lock and the vehicle
skids
• A skidding vehicle has less traction than a turning wheel and as a result the
driver has less control of the vehicle
• If the wheels can be prevented from skidding, the driver will be able to:
• Stop faster
• Have some control over the vehicle when the brakes are applied
19
20. Fluid Mechanics and Braking Systems 27/5/12
ABS or Anti-lock Braking System
Components of ABS ?
• Speed sensors - located in wheels. Detect when the wheels are about to lock
• ABS Controlled Valve - located in the brake line. The valve has three possible
positions:
1. Open - pressure from the master cylinder is passed directly to the
brake
2. Closed - The brake line is closed off from the master cylinder.
Prevents increase in brake pressure if the brake is pressed harder
3. Release - some (not all) pressure is released from the brake
• Pump - Restores pressure in the brake line sfter the valve has been activated
• Controller - a computer that monitors the speed sensors and controls the
valves
20
22. Fluid Mechanics and Braking Systems 27/5/12
How do the speed sensors work - Step 1
ABS speed sensors, mounted in the vehicle's wheel hubs constantly monitor the
rotation of each wheel to determine if the ABS needs to override manual braking
of the vehicle.
The speed sensors calculate
* revolutions of wheels as well as
* evaluating the continuity between all wheels.
If any differences are detected in rotation, the ABS is activated to control
braking.
22
23. Fluid Mechanics and Braking Systems 27/5/12
How do the speed sensors work - Step 2
Generating the Speed Sensor Signal
Speed sensors are made of:
A magnet wrapped in a coil and
A toothed sensor ring mounted around the CV joint hub.
When contact is made between the toothed ring and magnet, an electrical field is
given off forming a signal.
The signal includes measurements of the number of pulses per second created by
the electrical field existing between the magnet coil and sensor ring.
After conversion into digital form the signal is transmitted to the ABS
controller.
23
24. Fluid Mechanics and Braking Systems 27/5/12
How do the speed sensors work - Step 3
Sending Messages to the ABS Controller
This signal is passed along to the controller which counts the number of pulses.
This is used to determine wheel speed.
The ABS uses this data to determine whether it should intercede to control
braking
