If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
Which is an impossible value of efficiency for a heat engine?
100% efficiency is impossible for a heat engine working between two reservoirs at different temperatures according to the second law of thermodynamics.
What is the efficiency of a machine that requires 100 joules of input energy to do 35 joules of useful work?
The machine efficiency is 35 percent (35/100).
What would a machine that had 100 percent mechanical efficiency be called?
A machine with 100 percent mechanical efficiency would be called an ideal machine, as it would have no energy losses due to friction, heat, or other inefficiencies.
Why isn't it possible to attain an efficiency of 100 percent in heat engines?
It is impossible to achieve 100% efficiency in heat engines due to the second law of thermodynamics, specifically the Kelvin-Planck statement, which states that it is impossible for any device that operates on a cycle to receive heat from a single reservoir and produce an equivalent amount of work. Some amount of energy will always be lost as heat to the surroundings, limiting the maximum efficiency that can be achieved.
Does a refrigerator have 100 percent efficiency?
nothing has 100% efficiency.
If the output work of a simple machine is than the input work the machine is said to have less than 100 percent efficiency?
input
Can a car have a 100 percent efficiency?
No. Nothing mechanical can ever have a 100% efficiency by any physical evaluation.
What would cause the calorimeter efficiency to be less than 100 percent?
why is the efficiency of a calorimeter less than 100%
How does the output work compare to the input work for a machine that has an efficiency equal to 100 percent?
If a machine has 100 percent efficiency, the output work = the input work. That's actually basically what the efficiency of a machine is - output work / input work * 100.
How do you breed cool fire dragon 100 percent answer?
its impossible to breed cool fire dragon with 100 percent chance
Why is it that is impossible to have a 100 percent efficiency?
Achieving 100 percent efficiency is impossible due to the inherent limitations imposed by the laws of thermodynamics, particularly the second law, which states that energy transformations always result in some energy being lost as waste heat. Additionally, real-world processes involve friction, resistance, and other forms of energy dissipation that prevent complete conversion of input energy into useful work. Even in idealized systems, factors such as material imperfections and external influences introduce inefficiencies. Thus, some energy is always lost in any real process, making 100 percent efficiency unattainable.
When efficiency is at 100 percent it is known as what with power factor?
"Unity"
How do you get 100 percent in 13 subjects?
Impossible closest answer is 7,692....
Why can efficiency never can be 100 percent?
The laws of thermodynamics imply that there will always be some loss of efficiency.
Which is an impossible value of efficiency for a heat engine?
100% efficiency is impossible for a heat engine working between two reservoirs at different temperatures according to the second law of thermodynamics.
What is the formula to calculate percent efficiency?
(work out/work in) x 100
