Why is fuel density important?
Density is an important fuel property with respect to volumetric fuel economy and maximum power. In such cases lower NOx emissions are observed due to lower peak pressure and temperature, as well as lower PM emissions due to the overall leaning of the air/fuel mixture.
What is energy density of fuel?
In energy storage and fuels In energy storage applications the energy density relates the energy in an energy store to the volume of the storage facility, e.g. the fuel tank. The higher the energy density of the fuel, the more energy may be stored or transported for the same amount of volume.
How does density affect fuels?
Density is mass per unit volume. If a fuel has higher density than other, it means much more mass is entering into the combustion chamber for the same volume, since new generation diesel injectors which supply fuel into combustion chamber for power generation regulate the amount of fuel by volume, not by mass.
What fuel has the highest energy density?
hydrogen
Do fossil fuels have high energy density?
Fossil fuels are more energy dense than other sources. Natural gas, a fossil fuel that occurs in gaseous form, can be found in underground deposits on its own, but is often present underground with oil.
What is energy density food?
Energy density is the amount of energy or calories in a particular weight of food and is generally presented as the number of calories in a gram (kcal/g). Foods with a lower energy density provide fewer calories per gram than foods with a higher energy density.

What Greens last the longest?
Since most greens tend to wilt quickly, cabbage (both the green and red varieties) is your best long-lasting leafy friend. Wrap cabbage heads tightly in plastic and store in the crisper drawer. They’ll last around two weeks and up to a month.
What vegetables last longest?

How long is rice good for?

Can you live on rice?
Man Cannot Live On Rice And Beans Alone (But Many Do) : The Salt Rice and beans is a cultural icon in many parts of the world. It’s pretty healthy and relatively cheap. It may keep people from starving, as TV personality Sean Hannity suggests, but it doesn’t have all the nutrients a body needs for life.
Is Rice left out overnight safe to eat?
After cooking rice, you should not let it sit out for more than an hour. That bacteria can survive even after the rice is cooked, and the longer rice is left out at room temperature, the greater the chances the bacteria will multiply and potentially product toxins.
Is left over rice safe to eat?
Yes, it is fine to eat leftover rice for several days after it was initially cooked. Just make sure it was stored properly and wasn’t kept in room temperature for a long time. “Spores are present in food. “It’s OK to eat for several days if it’s stored correctly.”
Can leftover rice kill you?
You can get food poisoning from rice if you don’t store it in the fridge soon enough after cooking. What makes you sick is Bacillus cereus, says CSIRO food microbiologist Cathy Moir.
