Ther is no carbon in water

Unburnt fuel fills the chambers and silencer, causing the loud bang of a 'back fire'.

The volume is 22,1 L.

This sounds like a school problem. Do you want the answer in kg or moles? Pv=mRT for kg or Pv=nRT for moles m=Pv/RT or n=Pv/RT P=3000 psi v= (1/4)*D*Pi*L R for Nitrogen = 0.2968 kJ/kg-K for kg. For moles, use the universal gas constant, 8.31451 J/mole-K, and the molecular weight of Nitrogen is 28.01 g/mole Room Temp is 295 K Make sure to keep your units consistent

Paints were made with egg yolk and a colored pigment as long ago as the first century after Christ and up until the 1500s, when oil paints were invented.

Limestone or, to be more precise, reconstituted limestone is, perhaps, the oldest and technologically very advanced building material. Back nearly 5,000 years it was used by Ancient Egyptians to construct their pyramids (recent studies have shown that the pyramid bricks were made of limestone cement, and not cut as the longstanding belief assumed). The Romans simply took the existing technology and applied it to aqueducts, bridges and other constructions.

i have lost my roll no in B.A part 1 so till me what to do i.

1. A carbon pool is a reservoir with the capacity to store and release carbon, such as soil, terrestrial vegetation, the ocean, and the atmosphere.

The denser the styrofoam, the greater it's load bearing ability.

Google "pressure sensitive adhesives". Or go to the library and find a book on adhesives.

I'm guessing you mean high carbon to steam ratio. that gives rise to a proportionately greater volume of carbon monoxide being evolved.

if there is a lot of steam and only some carbon, you normally get the more stable CO2 but with insufficient steam, the less stable CO is evolved, ALONG WITH some CO2. =]

You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene).

In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation".

When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used.

Differenciation of components of petroleum is done by this process

Voltage measures electrical tension, Celsius measures temperature.

API X70 is one of line pipe grade family define by API 5L specification

Prandtl number is dimensionless number, denoted by Npr.Npr = Cp (viscosity)/(thermal conductivity)

Cp - specific heat, J per ( Kg Kelvin)

viscosity in poise (gm per( cm sec))

thermal conductivity in Watt per (meter kelvin)

Prandtl number is important in heat transfer.

The point of distillation (of alcohol) is to separate the ethanol from the other undesired components. The distillation process takes advantage of the different volatilities. In the fermented mash are undesired substances more volatile than ethanol (e.g. methanol) which will distill out first. This is the Heads and is discarded. Once these more volatile compounds are eliminated you have the Heart of the run which is the quality product. Finally if you keep distilling you begin getting some undesirable lower volatility substances, oils and water, the Tails, which is also discarded by stopping the distillation run. The art of the experienced distiller is to know when to draw the lines between Head, Heart, and Tail. The more selective one is, the higher quality (but less quantity) of the produced distillate.

due to pressure loss or sudden change in area the vaccum bubbles formed along with the inner surface of an ejector. it is known as ejectors cavitation.

The proportional integral and derivative control system or PID control system consists of proportionsl, derivative and integral elements which gives a very efficient process control.

They are designed to have a rope or cable fed through the ring in order to lift objects. The ring can be drop forged (one single piece, the eye being entirely closed) or bent to form a loop. Bent eye bolts should only be used in light duty applications and should never be used to execute angular lifts.

it is the pathway through which liquid products are sent to market or storage tanks.it is usually an assembly of pipes for the transfer of finished products to their target sites.

it is a branch of chemical engineering, to become a petrol engineer you will most likely first finish a bachelors in chemical engineering then continue a focus in petrol in graduate school.
