Q
how to calculate engine efficiency
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Engine efficiency can be calculated using the formula for thermal efficiency, which is the ratio of work done by the heat engine to the heat energy supplied to it.
Here's the step-by-step process:
1. Find the amount of energy supplied to the engine. This is typically measured in joules and can be found on the fuel you are using or is often given in problems.
2. Calculate or find the amount of energy or work the engine outputs. This is also typically measured in joules.
3. Divide the work output by the energy input and multiply the answer by 100 to get the efficiency percentage.
The formula to calculate engine efficiency is:
Efficiency = (Work Output/Energy Input) * 100%
For example:
If an engine produces 20,000 joules of work from 50,000 joules of energy input, the engine's efficiency would be (20,000/50,000) x 100 = 40%.
Note: Internal combustion engine efficiencies typically fall into a range around 25% to 50%. Electric engine efficiencies are often above 90%.
