how do you calculate how much gas you will need for a trip?
8873
Take the mileage of the total distance of your trip and divide it by your miles per gallon to get the number of gallons of gas you will need on your trip. Then multiply that figure by the current price of gas, and the result is the estimated cost of gas for your road trip.

All told, if you do the math and assume the best miles per gallon scenario, the majority of gasoline cars on American roads do not have a range of more than 400 miles. Basically, you need a gas tank size of 13 gallons and an average mpg of 31 to hit – just barely – the 400-mile range mark.

Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km.

P = Pressure (atm) V = Volume (L) n = moles R = gas constant = 0.0821 atm•L/mol•K T = Temperature (Kelvin) The correct units are essential. Be sure to convert whatever units you start with into the appropriate units when using the ideal gas law.

An example would be to calculate the volume that 56 g of nitrogen gas occupies. Get familiar with the ideal gas law. It can be written as: V = nRT/P. "P" is pressure, "V" is volume, n is the number of moles of a gas, "R" is the molar gas constant and "T" is temperature.

Take the current per-gallon price of diesel ($2.10) and divide it by your truck's miles per gallon. So, $2.10 divided by 5.7 equals 36.84 cents. If you round that number up, you are spending 37 cents on fuel for every mile your truck travels.

So, if you use your gas appliance for 2 hours a day. The total running cost of it would be: 30.36p (cost per hour) x 2 hours (number of hours in use) = 60.72p for 2 hours.

You would need to divide 1000 miles by 50 gallons of gas. That would equal 20; therefore, you traveled 20 miles for every 1 gallon of gas. Your gas mileage would be 20 mpg (miles per gallon). You may wish to use an online auto mpg fuel cost calculator.

To determine the number of BTUs per square foot that you need to heat a room, simply multiply the square footage by 20 BTUs per square foot. For example, if a room has 1,000 square feet, you would require 20,000 BTUs to heat it.

Divide the amount of Btus per hour by 1,000 to calculate the amount of MBH. For example, the amount of Btus per hour is 20,000. Dividing that by 1,000 would result in 20 MBH.

Divide this amount by the number of km travelled with this car for the year. This will give a rate per km travelled for that car. Add to this amount the below rate per km for fuel and maintenance to arrive at the total amount allowed as a deduction per business km travelled during a tax period.
