Which of the following is the correct formula for calculating the degree of reaction of a reaction turbine? |
| A. | R<sub>d</sub>= ( frac{2C_{bl}(C_{w1}+C_{w2})}{C_{r2}^2-C_{r1}^2} ) |
| B. | R<sub>d</sub>= ( frac{C_{r2}^2-C_{r1}^2}{2C_{bl} (C_{w1}+C_{w2})} ) |
| C. | R<sub>d</sub>= ( frac{C_{bl}(C_{w1}+C_{w2})}{2(C_{r2}^2-C_{r1}^2)} ) |
| D. | R<sub>d</sub>= ( frac{2(C_{r2}^2-C_{r1}^2)}{C_{bl}(C_{w1}+C_{w2})} ) |
| Answer» C. R<sub>d</sub>= ( frac{C_{bl}(C_{w1}+C_{w2})}{2(C_{r2}^2-C_{r1}^2)} ) | |
