Rankine Cycle Efficiency Formula
The following formula is used to calculate the Rankine Cycle Efficiency.
Erank = [(h2-h3) – (h1-h4)] / (h2-1) * 100
- Where Erank is the Rankine Cycle Efficiency (%)
- h2 to h3 (J)
- h1 to h4 (J)
- h2 to h1 (J)
How to Calculate Rankine Cycle Efficiency?
The following example problems outline how to calculate the Rankine Cycle Efficiency.
Example Problem #1
- First, determine the h2 to h3 (J). In this example, the h2 to h3 (J) is given as 30 .
- Next, determine the h1 to h4 (J). For this problem, the h1 to h4 (J) is given as 20 .
- Next, determine the h2 to h1 (J). In this case, the h2 to h1 (J) is found to be 15.
- Finally, calculate the Rankine Cycle Efficiency using the formula above:
Erank = [(h2-h3) – (h1-h4)] / (h2-1) * 100
Inserting the values from above and solving yields:
Erank = [30 – 20 ] / (15) * 100 = 66.66 (%)
Example Problem #2
Using the same method as above, determine the variables required by the equation. For this example problem, these are provided as:
h2 to h3 (J) = 40
h1 to h4 (J) = 5
h2 to h1 (J) = 100
Enter these given values yields:
Erank = [40- 5] / 100 * 100 = 35 (%)
