The calorific value of biofuels can vary depending on the type. For example, biodiesel typically has a calorific value of around 30-37 MJ/L (megajoules per liter), while bioethanol ranges from about 26-30 MJ/L. These values can fluctuate based on the feedstock and production methods used. Overall, biofuels generally have lower calorific values compared to conventional fossil fuels.
The calorific value of petrol is typically around 32-35 MegaJoules per liter. This means that when petrol is burned, it releases this amount of energy.
Calorific Value of diesel = 39,000 Kj/Liter 1 HP = 2685 Kj Total calorific value of 6.7 liter diesel = 39,000x6.7 = 2,61,300 Kj HP delivered = 2,61,300/2685 = 97.3 = 97.3x75 Kgf-m/sec
The calorific value of water is 80cal/degree. so it takes 60*80=2400cal of heat.
Petrol is a complex mixture of many hydrocarbons and other substances. If discussion is restricted to octane, C8H18, the standard enthalpy of formation -- the energy contained in its bonds -- is -250 kJ/mole (60 kcal/mole).
source:(http://en.wikipedia.org/wiki/Biofuel)we use biofuels because they do not make as much pollution as normal fuels.
It depends on: 1. Type of gas and its calorific value, 2. Volume of gas per minute/second, 3. Oxidiser and completeness of combustion.
You can not determine in terms of lbs what a human needs to eat a day. Different foods have different calorific/nutritional value per unit weight.
Weigh some 'oven dry' wood, which has had all it's moisture driven off, then use a bomb calorimeter to find out how much energy is released when it is burnt. You can use this to find out a value for how much energy is released (in MJ) per kg.
a lot... you should do it.
A Mcdonalds food nutrition chart lists all the items they sell. Net to each will be the calorific value and how much salt and sugar each contains for a protion .
As much as I know it's about 68%
The cost of biofuel per kilowatt (kW) can vary significantly based on the type of biofuel, production methods, and regional market conditions. Generally, the cost of biofuel can range from $0.05 to $0.20 per kWh, depending on factors such as feedstock prices and processing technologies. Additionally, subsidies and government policies can influence prices in different regions. For precise figures, it's best to refer to current market data or specific biofuel reports.
