To open the wizard, click on the corresponding button in the upper right corner of the Sensors tab of the unit properties. 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 . Search by Model. TSFC may also be thought of as fuel consumption (grams/second) per unit of thrust (kilonewtons, or kN). If you want, you can switch back and forth with a little math: divide 282.48 by the number of L/100 km to get Imperial m.p.g., or by the m.p.g. As for the boat, t… 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. With the aid of Ecotrons Fuel Injection chipset, all engine parameters and variables were meticulously noted for preliminary calculations. The fuel economy of an automobile relates distance traveled by a vehicle and the amount of fuel consumed. Convert km/litre to miles per gallon i.e. EPA gas mileage, safety, air pollution, and greenhouse gas estimates for new and used cars and trucks. Calculation of fuel consumption is made in accordance with the speed of the unit. GPH = (0.50 x 300)/ 6.1 = 150/6.1 = 24.5 GPH. Okay, first of all, MPG (called fuel economy) has always been a poor choice of units. Then convert each unit: 1 mile = 1.609 km = 0.01609 100km; 1 gallon = 3.785 liters. Calculate your car's real world MPG using our True MPG Calculator. fuel consumption is inversely proportional, meaning that doubling the mpg halves the fuel consumption. So this is equal to 400/25 gallons, which is the same thing as 400 divided by 25 is equal to 16 gallons. Your result should look like miles per gallon = A/ (liters/100 km). Different types of fuel make different amounts of power. One gallon of diesel fuel stores about 38 kilowatt hours of energy, or 130,000 BTU. Questions. Calculating gas mileage is important. A vehicle that gets 30 MPG will cost you $ 460 less to fuel each year than one that gets 20 MPG (assuming 15,000 miles of driving annually and a fuel cost of $ 3.70).Over a period of 5 years, the 30-MPG vehicle will save you $ 4625. The engine converts that energy into the power needed to overcome resistance and move the boat through the water. GPH = (0.4 x 300)/ 7.2 = 105/7.2 = 16.6 GPH. multiply km/litre by 2.825. Brake-Specific Fuel Consumption. Although students are not likely to recognize the relationship initially, the activity should help them arrive at that realization. To improve accuracy and practicality, the formula and the calculator below will include city miles and highway miles. 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. A car travels 950km on 75L of petrol. Formulae used for conversion and calculation of fuel consumption: Divide the distance by the litres used to get the km/litre. It's just dividing one by the number in question -- in this case, the number in question is your car's miles per gallon. Calculate its fuel consumption rate: Fuel consumption rates in L/km=75/950=3/38 =0.07895 L/km apprx. And then I have 400 times 1/25 gallons, which is the same thing as 400 divided by 25 gallons. Now it's always important to do a reality check here, not just to try to blindly cancel out units. 300-hp Gasoline Engine Example. 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. You may have observed the cost of fuel has been increasing over the last few years. Skip navigation Sign in. Calculate vehicle fuel economy in mpg US (miles per US gallon), mpg Imp (miles per Imperial gallon), km/l (kilometers per liter) or fuel consumption in l/100km (liters per 100 kilometers). ASVAB WEEKLY - FUEL CONSUMPTION PROBLEM. 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 value from the previous message till the current one is multiplied by the value from the point 5. Fuel Consumption - Displaying top 8 worksheets found for this concept.. It is thus thrust-specific, meaning that the fuel consumption is divided by the thrust. Reserves can generally be considered 10% of the total amount of fuel capacity for the airplane.
