# Fire Protection - Essay Example

Summary
Hydraulics is the branch of physics which study the mechanical properties of water and other liquids in motion with the application of these properties in engineering. Hydrodynamics is the study of the motion and action of water and other liquids. Hydrostatic is the balance of water and other liquids and the pressure exerted by them at rest…

It is essential that every fire fighter understand the behaviour of water in difference circumstances.
Most of the motions that we find on earth involve friction. Friction is a force which occurs when two surfaces rub against one another. If you roll a ball slowly across the floor, the ball's speed decreases and eventually it stops. It stops because the friction between the ball and the floor pushes against the ball and reduces its motion. When you rub your hands together, you feel the resistance due to friction. By rubbing your hands together, you are doing work. The result of this work is the heat produced.
Water when pure is colourless, odourless, and liquid with a molecular composition to two atoms of hydrogen combined with one atom of oxygen. A liter of water has a mass of 1 kilogram (1 kg), corresponding to a downward force of 9.81 newtons (N). A cubic meter of water exerts a downward force of 9810 N, or 9.81 kilonewtons (kN). This is more commonly reckoned as 10 kN. The mass of water varies with the degree of purity. Ordinary sea water 'weighs' approximately 10.0 newtons per liter (N/litres).
Pure water has a freezing point of 0...
It is virtually incompressible, and an increase of 1 bar only causes a decrease in volume of 0.000 002 per cent.
As a fluid, water has volume but is incapable of resisting change of shape, i.e. when poured into a container it will adjust itself irrespective of the shaper of the latter, and will come to rest with a level surface. This is because there is very little friction or cohesion between the individual molecules of which water is composed.
2. PrincipalCharacteristicsofPressure
There are six basic rules governing the principal characteristics of pressure in liquids. These are:
a. Pressure is perpendicular to any surface on which it acts
If a vessel having flat sides contains water, and that water has attained a position of rest, then the pressure on all sides of the vessel due to the weight is perpendicular to those sides, as shown by the direction of the arrows.
b. Pressure at any point of a fluid at rest is of the same intensity in all directions
In a line of piping or hose, two pressure gauges are inserted. If the water is at rest because a valve or hand-controlled branch has been shut down, the pressure gauges will register identical readings showing that the pressure at any point of a fluid at rest is the same in all directions.
c. Pressure applied from outside to a fluid contained in a vessel is transmitted in al directions
A hollow sphere with pressure gauges around the circumference has been filled with water, and pressure is applied. All the gauges will show the same pressure reading, providing that when pressure is applied to a fluid in a confined space, that pressure is transmitted equally in all directions.
d. Downward pressure of a fluid in an open vessel is proportional to its depth

... that people should undertake to use and control it (Pyne 271). Such founding concerns seemed like illogical arguments in the initial studies on fire and its management. Then, fire was simply there, flaring and smoldering across the earth, and there was need to determine its direction, its fierce, and its speed, and subsequently devise means to stop its spread. With time, other questions emerged, especially concerning economical and ecological, though with reference to the conception that fire was embedded in physical sciences. Fire had similar impacts to the society and biota as windstorms and floods did, yet this did not provide an answer to the question of fire management.

### Water Supply And Fire Protection Hydraulics

...Discuss your understanding of an attack pumper to help solve unusual and complex hydraulic problems on the fire ground. Attacks pumpers are hydraulic devices designed specifically to solve complex problems in hydraulics during firefighting and are constructed to apply water to control fire. Attack pumpers are also used earlier as mini pumpers and required limited staffing to handle fire fighting .It is ideal for attack pumpers to possess fire hose and desired pre-connected lines in order to support the attacks at the fire scene at a faster pace and maneuver the fire. Attack pumpers have a minimum pump rating of 250 gpm at 150 psi and also a minimum tank capacity of 200 gallons. Other features of the attack pumper include either 300 feet...

Fire fighting consists of removing one or more of the three elements essential to combustion-fuel, heat, and oxygen-or of interrupting the combustion chain reaction. Commercial and industrial buildings usually have some sort of internal, or private, fire-protection system installed. Some industrial establishments even airports also maintain fire departments that are specially trained and equipped to fight aircraft fires. The local fire department usually provides fire protection for the rest of the airport. Airport fire trucks are equipped with water and a substance...

### The European Convention for the Protection of Human Rights and Fundamental Freedoms

The United Kingdom is a member State and fully ratifies the jurisdiction of the European Convention for the Protection of Human Rights and Fundamental Freedoms. (Territorial Scope of the European Convention on Human Rights) The presumption of innocence has long since been a recognized principle of the British criminal justice system. However, the presumption has never been codified by legislative intervention but rather established firmly by common law precedents. The presumption of innocence obviates the necessity of placing the burden of proof on the prosecutor to prove the defendant’s guilt.

On the other hand, the change in the forms of employment has led to a decrease in employees’ performance in the high percentage of organizations internationally. Towards this direction, McGovern et al. (2004, 225) stated that ‘the rapid growth in nonstandard forms of employment toward the end of the 20th century has fuelled claims about the spread of "bad jobs" within Anglo-American capitalism; research from the United States indicates that such jobs have more bad characteristics than do permanent jobs after controlling for workers’. In other words, the bad conditions in the workplace – lack of communication and cooperation among the employees - but also between the employees and the firm’s owners - l...
