Are there any tables graphs or curves for gasoline density or weight and volume versus temperature?
The simple answer is yes. I know because I've used them in the past. However, I can't for the life of me find any examples at this point in time. I'll keep looking.
Consider how temperature affects the purchase of gas for your car...Refer to the expansion coefficients for the particular API Gravity @ 60 degrees F. These are referenced by ASTM Charts.
Example:
Ethanol @ at a gravity of 50.5 and say 70 degrees F would use a coefficient of .9940, what that is saying in simplified terms is if you but 100 gallons exactly and it is 70 degrees F, if you are buying net gallons or temperature compensated, you would pay for .9940 x 100 or 99.40 gallons.
This is how oil companies sell to each other.
Unfortunately, if you buy 100 gallons exactly from a pump at a station and it's 70 degrees F, you pay for 100 gallons. Doesn't hardly seem fair huh?
So let's do some math. Let's say I'm a fuel seller. I buy 10,000 gallons of fuel wholesale, temperature compensated or net gallons at 70 degrees F. So I pay for 9940 gallons. Remember 10,000 x .9940 = 9940, now I put it in my storage tank and lets say it's in Arizona and the ground temperature remains at 70 degrees F.
I just made 60 gallon profit on my sale. Since I sell it in gross gallons or uncompensated. Not a bad gig huh?
60 gallons x $4.00 / gallon = $240.00 profit clear.
So now you understand temperature compensation I hope? Smile for the camera next time you fill up. Especially if it's 90 degrees out.
EDIT: This would be true if the "Ground" temperature was EVER 70 Degrees. It is not.
When underground storage tanks for gas stations were first introduced, they were buried only several feet underground, where the temperature did indeed vary (but note, even 3 feet below ground would almost never see 70 degrees, only if it was about 100+ outside). Today, gas storage tanks are stored at 20+ feet below ground, where the temperature is a steady 55 degrees + or - 2 degrees, REGARDLESS of surface air temperature.
What else can I help you with?
How do you explain how graphs are used and what their advantages are?
Graphs show the relationship of one quantity to another. For example, it may show how the density of a material changes when the temperature is increased, or it may show the inflation depending on time. Vertically you show the quantity of interest (density, inflation) and horizontally what it depends on (temperature, time). You measure / look up / guess for each temperature the density, and draw a dot which is above the given temperature and to the right of the given density, and you do that for many densities.
Are line graphs the same as box and whisker plots?
No because box and whisker plots are related to cumulative frequency curves
What are the 3 steps for working with demand and supply graphs?
The three steps for working with demand and supply graphs are: Identify the Curves: Determine the demand and supply curves on the graph, ensuring you understand their slopes—demand curves generally slope downwards while supply curves slope upwards. Determine Equilibrium: Find the equilibrium point where the demand and supply curves intersect, indicating the equilibrium price and quantity in the market. Analyze Shifts: Assess any factors that may cause shifts in the demand or supply curves, such as changes in consumer preferences or production costs, and illustrate these shifts on the graph to understand their impact on equilibrium.
The hr diagram graphs what 2 things?
The temperature and luminosity of stars.
What does the solutions represent in graph?
Solutions may be closed or open regions or they may be points within a region (for example, grid points for integer solutions), or points of intersection between curves or between curves and the axes. It all depends on what the graphs and the solutions are.
What are the captions for the graphs that illustrate the keyword "global temperature trends"?
The captions for the graphs illustrating the keyword "global temperature trends" describe the data and trends in temperatures across the world over a specific period of time.
What are graphs showing average temperature and precipitation in a place?
A climograph is a graphical depiction of the monthly precipitation and temperature conditions for a selected place. Precipitation is shown by the bar graph. A line graph depicts temperature.
Are all graphs straight lines?
No, not all graphs are straight lines. Graphs can represent a wide variety of relationships, including linear, quadratic, exponential, and more complex functions. A straight line indicates a linear relationship, while curves or other shapes can indicate non-linear relationships. The type of graph depends on the mathematical function being represented.
How is a constant temperature indicated on graphs?
A straight line.
What is shown on a graph?
A graph is a visual representation of numerical or other information, often used for comparative purposes. Mathematical graphs include those in geometry that indicate points, lines, and curves within a Cartesian coordinate system. Other types of graphs (bar graphs, pie graphs) display numerical values or percentages as lengths or areas, and may use colors to indicate the data for more than one set of values.
Where are solutions to a system seen on the graph?
The intersection of the individual graphs. In the simplest case, the graph for each equation consists of a line (or some curve); the intersection is the points where the lines or curves meet.
What insights can be gained from analyzing pressure temperature graphs in the context of a chemical reaction?
Analyzing pressure-temperature graphs in the context of a chemical reaction can provide insights into the reaction's thermodynamic properties, such as changes in enthalpy and entropy. These graphs can help determine the reaction's equilibrium conditions, reaction rate, and the presence of any intermediate states. By studying these graphs, scientists can better understand the underlying mechanisms of the chemical reaction and optimize reaction conditions for desired outcomes.
