Essays on Diesel Fuel

The extraction of oil and natural gas has been a major industry in the United States for many years. Originally, this fuel was used simply to heat homes. With the advancement in technology, many different types of machinery, including electrical generators at power plants, automobiles and home appliances have been designed to operate using natural gas. In recent years, it has become more difficult to find new sources of natural gas. Hence, various companies have ventured in hydraulic fracking in the hope of producing more natural gas. However, the hydraulic fracking itself brings a host of environmental and health ...

If a fuel mixture can be represented by the general formula CxH2x, prove that the stoichiometric gravimetric air/fuel ratio is 14.8:1.

The combustion reaction for a given fuel mixture will look as follows:

CxH2x + 1.5x(O2 + 3.76N2) → xCO2 + xH2O + 1.5x*3.76N2 The molar ratio is 1.5x:1, to find the gravimetric ratio, the masses of the air and fuel should be found. This can be done by multiplying molar ratio with molar weights of the fuel and air. m(fuel) = 12*x + 2x*1 = 14x m(air) = 1.5x(16*2 + 3.76*14*2) = 1.5x*137.28 = 205.92x The gravimetric stoichiometric air/fuel ratio then is 205.92x:14x = 14.71:1 The dry exhaust gas analysis from an ...

Part 1: Scientific Method

The goal of using the scientific method is to determine cause and effect (Science Buddies, 2011). Keeping the five steps of the scientific method in mind for solving real world problems can save time and stop panic.

Scenario 1: You arrive home late at night. You walk up to the front door, unlock it, and reach in to turn on the light switch located just inside the front door. The light does not come on! Now what?

The first thing to do comes naturally; ask a question, “Why won’t this work?”

The second step is to gather background ...
