How many joules are lost to the environment for each 100 joules of chemical energy stored in the coal?
It depends on the efficiency of the coal conversion process. If the process is 30% efficient, then 70 joules would be lost to the environment for every 100 joules of chemical energy stored in coal.
How many joules are in 56 kilo joules?
There are 56,000 joules in 56 kilojoules. This is because there are 1,000 joules in a kilojoule.
Can you Convert 5.42 calories to joules?
Yes. 5.42 calories equates to 22.692456 joules.
What is the heat of solution for barium chloride in joules?
The heat of solution for barium chloride is -61.7 kJ/mol. To convert this to joules, multiply by 1000 to get -61,700 J/mol.
How many joules are in an apple?
An average apple contains about 52 calories, which is equivalent to approximately 217 joules.
What is the effciency of a car's engine when heat input is 2000000 joules and the waste heat is 1500000 joules?
The efficiency of the car's engine is calculated as the ratio of the useful work output to the total heat input. In this case, the useful work output is 500000 joules (2000000 J - 1500000 J) and the total heat input is 2000000 joules. Therefore, the efficiency is 500000 joules / 2000000 joules, which equals 0.25 or 25%.
What is the efficiency of a cars engine when heat input 2000000 joules and waste heat is 150000 joules?
The efficiency of the car's engine can be calculated using the formula: Efficiency = (Useful energy output / Total energy input) * 100%. In this case, the useful energy output is the heat used for work, which is (2000000 - 150000) Joules. Therefore, the efficiency would be ((2000000 - 150000) / 2000000) * 100% = 92.5%.
What is the efficiency of a car's engine when the heat input is 100000 joules and the waste heat is 75000 joules?
25%
What is the efficiency of lawn mower's engine when the heat input is 1000 joules and the waste heat is 750 joules?
25 percent
What is efficiency of lawn mower's engine when the heat input is 1000 joules and the waste heat is 750 joules?
25 percent
What is the efficiency of a car's engine when he input is 20000 joules and the waste heat is 15000 joules?
The efficiency of the car's engine is calculated by dividing the useful energy output by the energy input. In this case, the useful energy output would be 5000 joules (20000 input - 15000 waste heat), thus the efficiency would be 5000/20000 = 0.25 or 25%.
What is efficiency measured in?
Efficiency is measured in joules.
If an engine must do 500 joules of work to pull a 100 newtons load up to a height of 4 meters What is the efficiency of the engine?
400
What is the efficiency of a street cleaners engine when is that heat input is 200000 Joules and the waste he is 150000 Joules?
The efficiency of the street cleaner's engine is calculated by dividing the useful output (work done) by the input energy. In this case, the useful output is 150000J (work done) and the input energy is 200000J. The efficiency would be 150000J / 200000J = 0.75 or 75%.
What is the machine efficiency of a machine that produces 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
If an engine must do 500 joules of work to pull a 10 kg load up4 meters what is the engine's efficiency?
energy required to lift up 10kg=10x9.81x4=392.4 joule. enegy produced by the engine=500 joule efficiency=392.4/500=78.48%
What is the mechanical efficiency of a machine that produce 400 joules of work output from a work input of 500 joules?
The efficiency is 80%. To find the efficiency, 400/500 = 80%.
