Iraq's fields produce from numerous formations, with varying crude densities. Many of these fields have large ranges, such as the Mauddud formation with a range of densities 12 to 38 degrees API. The two largest fields Kirkuk and Rumaila have average gravities of 32 to 33 degrees API. To convert from degrees API to specific gravity (SG), SG = 141.5/(131.5+API) See related links.
the main reason why ethanol burns differently then ethanol and water mix is mainly because when you add the water to the ethanol you are making the ethanol less potent so it will burn weaker.
Around 138,370 Btu per gallon, according to ATRI: ULSD Has More Energy Than Engineers First Expected] (1/26/2009). This is 7.227 Gal/MMBtu. Thare are other numbers commonly in use, 139,200 and 140,000.
ethanol is a solvent
No, ethanol is an organic basic liquid, wine and beer contain ethanol, and it is flammable
API gravity is inversally proportional to the specific gravity. so if the value of spcific gravity for some material is higher , it means that the API gravity of the same material will be lower.

°API = [ 141.5 / (SG @ 60°F) ] - 131.5 SG= specific gravity (always taken at 60°F when calculating API)
The Formula for convert API gravity to pounds per gallon is: Pounds per Gallon = (141.5/(API Gavity+131.5))*8.3378 <--[which is weight of fresh water] API of 10 is same as weight of water. API >10 will float
By using API gravity value of a liquid we can check that how a liquid is lighter or haavior one.First we should know about API gravity.The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a liquid is compared to water. If its API gravity is greater than 10, it is lighter and floats on water; if less than 10, it is heavier and sinks. API gravity is thus an inverse measure of the relative density of a petroleum liquid and the density of water, but it is used to compare the relative densities of petroleum liquids. For example, if one petroleum liquid floats on another and is therefore less dense, it has a greater API gravity. Although mathematically, API gravity has no units (see the formula below), it is nevertheless referred to as being in "degrees". API gravity is graduated in degrees on a hydrometer instrument. The API scale was designed so that most values would fall between 10 and 70 API gravity degrees.M.Hassan Haq NawazB.sc. Chemical Engg,University Of Gujrat,Pakistan

the answer is yes.
What is crude densities? Crude densities are measured in api gravity. Api gravity is found by placing a hydrometer in a cylinder of crude at 60 degrees Fahrenheit and reading the depth the hydrometer has sunk into the crude.
crude weight starts at 10 being the highest!
Specific gravity of crude oil is how light or heavy it is compared to water. If the API gravity is less than 10 it will float in water.
Lower API crude requires treatment in high temperature and longer retention time to meet proper oil production specification Note - lower API (light crude) is free flowing while higher API (heavy crude) does not flow easily.
Depends on the API gravity. During the summer, diesel will weigh between 6.951 (API 38) and 7.076 (API 35) pounds per gallon. Last winter, the diesel weighed around 7.206 (API 32) pounds per gallon. You can do the math to convert this to metric.
