Chemical Engineering

It's a process called "vulcanization."

Please see BS 970 for detailed description.

The chemical composition is:

- C: max. 0,2 %

- Mn: 0,5-1,o

- Si: max. 0,35

- S: 0,04

- P: 0,04

- Cr: 0,75-1,25

- Ni: 1,0-1,5

- Mo: 0,08-0,15

If the fire is hot enough, and there is enough oxygen, the steel will burn. (think cutting torch) The simplest answer is that the steel heats up. A cutting torch doesn't "burn" the metal away... it melts the metal along your cutting line. Very few chemicals can oxidize steel with enough ferocity to burn it with a flame. A couple of exceptions that I have seen in my career were F2 and ClF3. Of course those are very strong oxidizers. Heating steel to a prescribed temperature then either quenching it quickly or holding the temperature a a certain level for a period of time will alter the grain structure and therefore the properties of the steel. Think tempering. You can learn much more about that by researching steel phase diagrams. Time-temperature relationships are the oldest and most common methods of changing a metals strength and hardness.

As low as 126 degrees Fahrenheit, diesel fuel could potentially catch on fire. This is known as the temperature of ignition.

Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.

Fretting corrosion is a complex process which involve chemical corrosion and friction (by asperities, surface irregularities) between components in motion, fluids moving in tubes, etc.

Muriatic Acid is good at dissolving cement, as well as RoMix Back Set Molecular Cement Dissolver

A positive displacement pump ( gear, vane or piston pump) is driven by a prime mover (Electrical Motor or Engine) it sucs fluid from reservior and delivers oil to system. During loading a resistance to flow creates the pressure which is utilised to do the work through cylinder for linear motion or through hydraulic motor for rotary motion, Direction of flow is changed with help of direction control valve & system pressure is regulated by pressure control valve & flow is regulated by flow control valve

galvanized metal is a silvery gray colour which also has a pattern on it.

These two laws they are similar.

But Hooke's Law is a law which is used in Solid Mechanics, and Newton's Law of Viscosity is the one which is used in Fluid Dynamics.

Fused silica has 2 meanings: previously fused silica and presently fused silica.

Previously fused silica is fused by heating it to its melting point. This can be done in crucible in a furnace.

Presently fused silica is already hot and fused.

Note: melted silica is probably a conductor, at least melted glass is a conductor.

A gas will always have a lower density than its corresponding solid or liquid, and thus could not sink in its own liquid.

Gasses can, of course, be absorbed/dissolved into liquids.

One of the least dense liquids would be liquid hydrogen with a density of about 67.8 kg/m3

One of the densest gasses (at 1 ATM) is Radon Gas at about 9.73 kg/m3. Thus, it would still float in liquid hydrogen at 1 ATM.

However, the density of gasses is a function of the pressure and temperature, so at extreme pressures, Radon gas would likely sink in liquid hydrogen.

The density of the atmosphere at the surface of Venus is about 67 kg/m3, and thus it might sink in liquid hydrogen (ignoring, of course, the temperature and pressure differences).

An average electronic engineer makes about $85, 350 per year. This amount can go above $125,000 or fall down below $52,000 per year. Electronic engineer's work is to create, test and oversee various electronic devices.

Yes it was to the moon, but they didn't actually get to land on the moon due to mechanical failures. 3 fuel tanks had blown up so they had to go home they landed in the pasific ocean

The mission lasted from April 11 to 17th 1970.

MEK or Methyl Ethyl Ketone will dissolve rubber. Acetone works great as well, fingernail polish remover.

Iron is not a carcinogen. Iron is a mineral which can be found in a human body. Even iron oxide is not a carcinogen.

Thermodynamics study about the interchange of heat and work between a system and the surroundings which occurs when the system undergoes a process. Thermodynamic also concerned about the changes in the properties of fluid. Most thermodynamics substances such as gases and vapours are often referred as P-V-T substances. An ideal gas obeys the equation of state that relates the pressure, specific volume or density, and absolute temperature with mass of molecule and the gas constant, R. However, real gas does not absolutely obey the equation of state. A few modifications on the ideal gas equation of state allow its application in the properties of real gas. When energy is added within water, the increasing of activities among the molecules caused the increase in the number of molecule escape from the surface until an equilibrium state is reached. The state of equilibrium depends on the pressure between the water surface and steam. The lower the pressure, the easier the molecules leaving the water surface and thus less energy is required to achieve the state of equilibrium (boiling point). The temperature where equilibrium occurs at a given pressure level is called saturated temperature. The pressure where equilibrium occurs at a given temperature is called saturated pressure. Marcet Boiler is used to investigate the relationship between the pressure and temperature of saturated steam in equilibrium with water at all temperature. The conducted experiment provides us a clear image on the progressing in between pressure, time and temperature. As time increased, the increased temperature energized the molecules of the water and thus, pressure became higher until the state of equilibrium.

At the boiling point the energy goes into breaking the intermolecular bonds, but the average kinetic energy stays constant and so does the temperature until all of the bonds are broken and the substance is in the vapor state.

It varies enormously. See the link below to a table showing all sorts of glass and glass-like products:

2.6g/cm3

2600Kg/m3

Also glass sinks because it has a density higher than 1.0g/cm^3.

Chemical engineers use Optimization Techniques and Operations Research to optimize and bring out the most suitable design with appropriate parameters.

Chemical engineers use Computational Fluid Dynamics involving lots of complex calculus to solve complicated fluid system and heat transfer problems.

Chemical engineers fit data for accurate graphical analysis using methods of regression and other graph techniques.

Chemical engineers use Partial Differential Equations and Ordinary Differential Equations using either manually or by Polymath, Matlab, Wolfram Mathematica to solve and get a solution to system of equations.

Chemical engineers use Numerical Analysis and techniques to solve a variety of problems based on the dynamic nature of the system.

Chemical engineers use Surface Volume, Area, 3-D geometry and vector algebra for material analysis and assessing physical parameters to plant systems and units.

There are 3 types of weathering Physical Weathering which is split into two parts a.Freeze-thaw-as water enters cracks and holes it freezes and expands dueing for the rock to form cracks and breaking of the rock bunion skin (Exfoliation)-As the rock heats up and expands by day, and cools and contracts by night, stress is often exerted on the outer layers. The stress causes the peeling off the outer layers of rock in thin sheets. 2. Biological weathering- the roots and animals burrow into rocks which causes them to break. 3. Chemical weathering- mineral dissolving in the water makes the water acidic which then eats away the rock and sometimes causes holes.

I think petroleum engineering has to do with the discovery of crude oil[hydrocarbons] in it's dark,sticky,viscous stage and lifting it to the surface and passing it to the refineries for the extraction of other components viz petroleum gases,petrol,kerosene . While gas and oil engineering has to do with reserving,distribution of refined oil and gas from crude oil to depots. Ismail Sani Ali.

The most familiar use of thermosetting plastic is the heat-resistant handle on metal cookware. It is also used for bottle caps, knobs and handles, and laminated counter tops. Thermosetting plastics retain their shape and strength even when heated.

Cable systems provide rates of approximately 500 Kbps downstream and 128 Kbps upstream. Theoretically they can provide a bandwidth of 30 Mbps. A DSL system can provide speeds of up to 7.1 Mbps, but most providers offer a maximum of 1.5 Mbps upstream and downstream.
