Gasoline is primarily octane. Octane has a density of 703 kg/m3 and a heat of combustion of 46.8 MJ/kg. How much energy would 100 L of gasoline produce? Answer in megajoules.
2. The total heating value of liquid propane after vaporization is 35.4 MJ/kg and that of heating oil is 45 MJ/kg. The average prices of heating oil and liquid propane are $3.18 and S2.65 per US gallon respectively (density of heating oil and liquid propane are 3.4 and 2.2 kg/US gallon respectively) but an after burning clean up equipment costing $10,000 that would last for 25 years would be needed for using heating oil as fuel. What type of fuel...
Suppose gasoline has an emissions factor of 92g of CO2/MJ and costs $1.78/liter, and biodiesel has an emissions factor of 54g of CO2/MJ and costs $2.05/liter. You may assume gasoline and biodiesel both have energy densities of 38 MJ/liter. What is the cost of mitigating CO2 by switching from gasoline to biodiesel, in dollars per kilogram of CO2 emissions prevented? We'll cover how to do calculations like this in the course, so don't worry if you struggle. Give it your...
Pure gasoline has an energy density of 115,600 BTU per gallon, while ethanol has an energy density of 75,670 BTU per gallon. Gasoline costs $2.6 per gallon. What would the price of E85 (85% ethanol, 15% gasoline) have to be for its energy cost to be the same as that of pure gasoline? The price of E85 is determined to be_____
BoNUs: Energy Storage Consider the capacitor as a device for storing energy. The practical limitation on the potential difference between the plates of a capacitor is the "dielectric strength" of the dielectric material between the plates. This is the maximum field strength that can exist without causing a spark. It is typically on the order of 107 v/m for a good liquid dielectric with K ะ 2.3 and ะ 1 g/cm3 (a) Neglecting the weight of the electrodes and case,...

How much total energy (in MJ) is contained by a tank holding 287 kg of water if that tank is in the back of a truck that is traveling at 35 m/s at an elevation of 298 m, and the specific internal energy of the water is 60 kJ/kg?
If a blend of gasoline has an energy content of 11,670 Wh/kg, how much fuel (in gal) is needed to convert 353 gal of water at 81.3oC to steam at 100oC? Assume all of the energy of the fuel is completely transferred to the water. The density of the fuel is 0.777 g/mL. 1 Wh is equivalent to 3600 J.
