Although students are not likely to recognize the relationship initially, the activity should help them arrive at that realization. For airplanes that are able to fly by "IFR" (Instrument Flight Rules), or with instruments, the reserves will be higher. Observations regarding the fuel economy of an automobile, designing a comparison of two different vehicles, the amount of fuel used by each. The Math of Fuel Mileage. Brake-Specific Fuel Consumption. You may have observed the cost of fuel has been increasing over the last few years. to get L/100 km. ASVAB WEEKLY - FUEL CONSUMPTION PROBLEM. The inverse, GPM (called fuel consumption), would therefore be a better measure, and is akin to the measure used in some parts of the world (e.g., Europe’s liters per 100 km). TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (kilonewtons, or kN). Air–fuel equivalence ratio, λ (lambda), is the ratio of actual AFR to stoichiometry for a given mixture. 2011-06-10 Diandra Engines, Fuel, Kansas, Pocono 6. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH. Then convert each unit: 1 mile = 1.609 km = 0.01609 100km; 1 gallon = 3.785 liters. Many people mistakenly believe that it is an indicator of rich or lean fuel mixtures, but it is actually a measure of efficiency that indicates how well the engine uses the fuel it burns. Okay, first of all, MPG (called fuel economy) has always been a poor choice of units. The official governing body and the automakers use those figures, and as a result, so do we. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH. There is a direct relationship between λ and AFR. As for the boat, t… Compare the gas mileage and greenhouse gas emissions of new and used cars and trucks Reserves can generally be considered 10% of the total amount of fuel capacity for the airplane. Fuel consumption in cars is one of the most important factors to know while owning and driving a car. Usually, you will see MPG (miles per gallon) rating as 20 CITY / 30 HWY And then I have 400 times 1/25 gallons, which is the same thing as 400 divided by 25 gallons. Side-by-Side comparison of cars and trucks. The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Equivalent fuel economy/efficiency ratings are converted and shown for all units, mpg US, mpg Imp, km/l and l/100km. fuel consumption is inversely proportional, meaning that doubling the mpg halves the fuel consumption. Brake specific fuel consumption (BSFC) is frequently misunderstood. λ = 1.0 is at stoichiometry, rich mixtures λ < 1.0, and lean mixtures λ > 1.0. If the sum of the coefficients is less than 0 or invalid, the total coefficient will be 1. Now it's always important to do a reality check here, not just to try to blindly cancel out units. So, using the Lamborghini example above, it's 1 divided by 12.5 and for the Geo Metro, it's 1 divided by 37.7. We use the fuel consumption formula to calculate the fuel consumption rate. [Training Article] Before Fueling Your Boat by Boat-ed.com [Video] How To Safely Fuel A Boat by Boat-ed.com. To improve accuracy and practicality, the formula and the calculator below will include city miles and highway miles. divide 100 by km per litre. The fuel contains the stored energy and we can describe that in terms of horsepower (hp), kilowatts (kW), or British thermal units (BTU). A given hull will require a certain amount of energy to move it through the water. I know NASCAR likes to portray itself as simple, but let’s give the folks sitting with all the computers up on the pit box their due. Convert the km/litre to L/100 km i.e. If we interpret the Criterion for Maximum Fuel Mileage in noncalculus terms - replacing (dv/v) and (dq/q) by small percentage changes in v and q, the economic principle seems to be that fuel efficiency is optimized when small percentage changes in v produce approximately equal percentage changes in q.Another characterization is that the v elasticity of q is 1 . The first think to notice is that one is distance/volume and the second is volume/distance, so they will be inverses of each other. brake specific fuel consumption = fuel pounds per hour / brake horsepower bhp loss = elevation in feet / 1000 x 0.03 x bhp at sea level Formulas for indicated horsepower & torque horsepower = mep x displcement x rpm / 792,00 torque = mep x displacement / 150.8 mep = hp x 792,000 / displacement x rpm mep = hp x 792,000 / displacement x rpm The Tsiolkovsky rocket equation, classical rocket equation, or ideal rocket equation is a mathematical equation that describes the motion of vehicles that follow the basic principle of a rocket: a device that can apply acceleration to itself using thrust by expelling part of its mass with high velocity can thereby move due to the conservation of momentum.
