Enter the output and input energy values into the calculator to determine the system efficiency. The efficiency is calculated as a percentage.
System Efficiency Formula
The following formula is used to calculate the system efficiency:
E = (OE / IE) * 100
Variables:
- E is the efficiency (%)
- OE is the output energy (joules)
- IE is the input energy (joules)
To calculate the system efficiency, divide the output energy by the input energy and then multiply by 100 to get the percentage.
What is System Efficiency?
System efficiency is a measure of how effectively a system converts input energy into useful output energy. It is expressed as a percentage and indicates the proportion of input energy that is successfully transformed into the desired form without being lost as waste energy. High system efficiency is desirable as it means less energy is wasted and operating costs are lower.
How to Calculate System Efficiency?
The following steps outline how to calculate the System Efficiency.
- First, determine the output energy (OE) in joules.
- Next, determine the input energy (IE) in joules.
- Use the formula from above = E = (OE / IE) * 100.
- Finally, calculate the System Efficiency (E) in percentage.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
Output energy (OE) = 150 joules
Input energy (IE) = 200 joules
