Work Ratio Formula:
| From: | To: |
The Work Ratio in practical cycle is defined as the ratio of net work to the total turbine work. It is an important parameter in thermodynamic cycle analysis, particularly in gas turbine and jet engine performance evaluation.
The calculator uses the Work Ratio formula:
Where:
Explanation: The formula calculates how much of the turbine work is available as net work output after accounting for the work consumed by the compressor.
Details: Work ratio is crucial for evaluating the efficiency of practical thermodynamic cycles. A higher work ratio indicates better cycle performance, as more of the turbine work is available as useful output.
Tips: Enter both compressor work and turbine work in Joules. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the typical range of work ratio values?
A: Work ratio typically ranges between 0 and 1, with values closer to 1 indicating more efficient cycles.
Q2: Can work ratio be negative?
A: In practical cycles, work ratio should be positive. A negative value would indicate that compressor work exceeds turbine work, which is not feasible in normal operation.
Q3: How does work ratio relate to cycle efficiency?
A: While work ratio indicates the proportion of useful work, cycle efficiency considers both work output and heat input to evaluate overall performance.
Q4: What factors affect work ratio in practical cycles?
A: Component efficiencies, pressure ratios, and temperature ratios all influence the work ratio in thermodynamic cycles.
Q5: Is work ratio the same as thermal efficiency?
A: No, work ratio focuses on the mechanical work relationship between compressor and turbine, while thermal efficiency considers the complete energy conversion process.
