The study of fluid mechanics goes back at least to the days of ancient Greece, when Archimedes investigated fluid statics and buoyancy. Medieval Persian & Arab natural philosophers, including Abu Rayhan al-Biruni and Al-Khazini, combined that earlier work with dynamics[1] to presage the later development of fluid dynamics. Rapid advancement in fluid mechanics began with Leonardo da Vinci (observation and experiment), Evangelista Torricelli (barometer), Isaac Newton (viscosity) and Blaise Pascal (hydrostatics), and was continued by Daniel Bernoulli with the introduction of mathematical fluid dynamics in Hydrodynamica (1738). Inviscid flow was further analyzed by various mathematicians (Leonhard Euler, d'Alembert, Lagrange, Laplace, Poisson) and viscous flow was explored by a multitude of engineers including Poiseuille and Gotthilf Heinrich Ludwig Hagen. Further mathematical justification was provided by Claude-Louis Navier and George Gabriel Stokes in the Navier–Stokes equations, and boundary layers were investigated (Ludwig Prandtl), while various scientists (Osborne Reynolds, Andrey Kolmogorov, Geoffrey Ingram Taylor) advanced the understanding of fluid viscosity and turbulence. Fluid mechanics is a subdiscipline of continuum mechanics, as illustrated in the following table. In a mechanical view, a fluid is a substance that does not support shear stress; that is why a fluid at rest has the shape of its containing vessel. A fluid at rest has no shear stress.

1. Home Hvac: Providing Comfort
November 01, 2009
HVAC (pronounced either as "H-V-A-C" or "H-vak") is an acronym that stands for the directly related functions of "Heating, Ventilating, and Air Conditioning"- the technology meant for indoor environmental comfort. HVAC (Heating Ventilation Air Conditioning) system design is a most important sub discipline of mechanical engineering, working using the principles of thermodynamics, fluid mechanics, and transfer of heat. Refrigeration is at times added to the field's abbreviation as HVAC&R or HVACR, or ventilating is dropped like in HACR (such as the designation of HACR-rated circuit breakers). ... (read more)

2. Why Check Your Car's Brake Fluid?
October 15, 2009
Here are a few important mechanics tips on how to check your car brake fluid level.
First, raise the hood. The master cylinder (mc) is located on the driver's side near the firewall, just under the windshield. Most master cylinders have two small round caps that you can twist off. Some have one rectangular cap that either snaps on or has a metal bar that clips over the cap.
You can remove the metal clip by inserting a screwdriver under the clip and lifting up on the handle. The plastic rectangular cap can be removed by popping it off with your thumbs.
Be extra careful removing t... (read more)

3. How to find good professional help for your Sexless Marriage!
September 24, 2009
When I had a used 1964 Chevy while in college, I could service much of the mechanics by myself. Today, all I can do is fill up the windshield washer fluid, and add air to the tires. That's about it. I need help with everything else.
Below you will find helpful suggestions, organized in the same 5 Challenge Areas that make up my Integrated Model for Online Sex Advice, which you can learn about.
There is a recurring theme to my advice - Take responsibility for your own life! Be proactive about your own care. Don't be passive, but be active in your attention to your own life.

7. Importance of Particle Size for Nebulized Medication
March 24, 2009
The physics of inhaled pharmaceutical aerosols (IPAs) is complex and involves aerosol mechanics, multiphase fluid mechanics, transport phenomena, and interfacial science, (in addition to pharmaceutics, chemistry, physiology, and medicine). Present understanding and prediction of the behaviour of IPAs remains relatively undeveloped.
Many researches are aimed at exploring and controlling the physics of inhaled pharmaceutical aerosols. Such aerosols are used in the therapeutic nebulized medication treatment of lung and respiratory diseases such as asthma, cystic fibrosis and even sinusitis,... (read more)

8. How Do you Find a Good Automobile Mechanic
February 16, 2009
Some people are ready to take on any task involving their car and think nothing of opening the hood at the first sign of car trouble. For the rest of us, who may be mechanically challenged or possess no interest in car repair, auto mechanics exist to do all of those things that we'd rather not do, such as oil changes and brake fluid flushing. Auto mechanics also perform highly specialized work such as tire alignment and transmission work; and even the most knowledgeable do-it-yourselfer will need to have their car serviced by a mechanic some day.
So how do you find a good mechanic?

9. The Acura Master Cylinder and Quality Brakes
August 28, 2007
The Acura master cylinder ensures that car owners are able to have top quality breaks and clutch systems. The master cylinder is a hydraulic control device that converts physical pressure (exerted when the driver steps on the pedal) into hydraulic pressure. By converting physical pressure, the other devices in the hydraulic system are allowed to operate as well. Employing this pressure, the Acura master cylinder is able to distribute the hydraulic brake fluid to all the rest of the brake system components.
The mechanics of the Acura Master Cylinder is quite simple. When one steps on th... (read more)

10. CAR ESSENTIALS: BRAKE BLEEDING AND BRAKE TOOLS
August 07, 2007
Brake fluid absorbs water from the atmosphere, lowering its boiling point and causing corrosion. Particulate contamination--microscopic particles of rust and rubber-hastens wear of moving components. This is why manufacturers and mechanics recommend fully flushing hydraulic fluid annually. In addition, whenever the hydraulic system has been opened it must be bled of air. You should also routinely flush and replace your brake fluid every two years. Deposits and debris can build up in the lines over time and decrease the efficiency of your brakes. Regular brake bleeding can also help you spot br... (read more)
