What does 35 percent efficient mean?
A system that is 35 percent efficient converts 35 percent of the input energy into useful work or output, while the remaining 65 percent is lost, often as waste heat or through other inefficiencies. For instance, in an engine, if it burns fuel to produce power, a 35 percent efficiency means that only 35 percent of the fuel's energy is effectively used for propulsion, with the rest wasted. This efficiency rating helps gauge performance and indicates potential areas for improvement.
Which component is NOT needed in a typical overhead cam engine?
I can only guess, but a push rod is a correct answer.
Is edenpure a efficient electric space heater?
Efficient, yes. But a poor choice for a heater. It's just a marketing gimmick. Every electric heater is nearly 100 percent efficient. Efficiency is a term not understood by many. Energy efficiency - useful work per quantity of energy. In other words, What is the job of an electric heater? To make heat. How much of the electricity fed to the heater is turned into heat? All of it. That makes it 100 percent efficient. In contrast an incandescent light bulb is only about 5 percent efficient, only 5% of the electricity fed to it is converted to light the other 95% is converted to heat.
Wy is the transfer of energy and matter in a food chain only about 10 percent efficient?
The transfer of energy and matter in a food chain is only about 10% efficient due to energy loss at each trophic level. This loss occurs through processes such as respiration, heat loss, and incomplete digestion. As a result, only a small portion of the energy consumed by organisms is converted into biomass that can be passed on to the next trophic level.
Why is there only 0.4 percent of oxygen in the exhaust gases coming out of the car engine?
There is only 0.4 percent of oxygen in the car exhaust gases coming out of a car engine because most of it is used up in the combustion process. Exhaust fumes also contain carbon monoxide.
Is there anything special about the smart car's engine?
No, it is typical turbo charged engine. It does have only 3 cylinder but that is nothing new and has been done before. It does have an unusual manual transmission that has no clutch pedal.
Is Gas more energy efficient for Cooking?
Gas cooking should be more energy efficient than electric, as the thermal energy from burning the gas goes directly into the food in the pan, whereas if the gas is used in a power plant you probably lose about 60 percent of the energy, only 40 percent goes into making the electricity
Can a device be 100 percent efficient when it comes to heat transfer?
Only if you're referring to an electric heater ... since all loses are also heat. The real world answer is no.
Which is the most efficient fuel engine?
The most efficient fuel engine is generally considered to be the hydrogen fuel cell engine, which converts hydrogen gas into electricity with water vapor as the only byproduct. Fuel cells can achieve efficiencies of up to 60%, and when used in hybrid systems, overall efficiency can be even higher. However, traditional internal combustion engines, particularly those using diesel fuel, can also be quite efficient, reaching around 30-40% efficiency under optimal conditions. The choice of the most efficient engine often depends on specific applications and energy sources available.
How many people are accepted into Princeton?
Only seven percent of students who apply to Princeton will be accepted. The students who are accepted to Princeton have graduated in the top ten percent of their class.
Is fuel injection for diesel engines more efficient?
diesel only comes in fuel injection, the fuel needs high pressure to ignite, and cannot only be sucked in like with a carburator on a petrol engine
What are the differences between bronze through platinum power efficiency on power supply's.?
The 80+ certification ensures that the power supplies you're buying achieves at least 80% efficiency from power draw (out from the outlet) to what your computer actually gets. The Bronze to Platinum and Titanium ratings up the minimum requirements from as high as 85 to 90% efficiencies.
