Heat Engine Work Formula
The following formula is used to calculate the Heat Engine Work.
Whe = Q1 – Q2
- Where Whe is the Heat Engine Work (J)
- Q1 is the initial thermal energy (J)
- Q2 is the final thermal energy (J)
How to Calculate Heat Engine Work?
The following two example problems outline how to calculate the Heat Engine Work.
Example Problem #1:
- First, determine the initial thermal energy (J). In this example, the initial thermal energy (J) is given as 70.
- Next, determine the final thermal energy (J). For this problem, the final thermal energy (J) is given as 30.
- Finally, calculate the Heat Engine Work using the equation above:
Whe = Q1 – Q2
Inserting the values from above and solving the equation with the imputed values gives:
Whe = 70 – 30 = 40 (J)
Example Problem #2:
Using the same process as above, first define the variables required by the formula. In this case, these values are:
initial thermal energy (J) = 90
final thermal energy (J) = 13
Entering these values yields:
Whe = 90 – 13 = 77 (J)
