Which of the following is the correct formula for calculating the degree of reaction of a reaction turbine?

Rd=\(\frac{C_{bl}(C_{w1}+C_{w2})}{2(C_{r2}^2-C_{r1}^2)} \)

Rd=\(\frac{2C_{bl}(C_{w1}+C_{w2})}{C_{r2}^2-C_{r1}^2} \)

Rd=\(\frac{C_{r2}^2-C_{r1}^2}{2C_{bl} (C_{w1}+C_{w2})} \)

Rd=\(\frac{C_{bl}(C_{w1}+C_{w2})}{2(C_{r2}^2-C_{r1}^2)} \)

Rd=\(\frac{2(C_{r2}^2-C_{r1}^2)}{C_{bl}(C_{w1}+C_{w2})} \)

In a single stage reaction turbine, the mean blade velocity is observed to be 200 m/s and the nozzle angle is 20°. The absolute value of the steam leaving the nozzle is 350 m/s. The factor with which the relative velocity of steam changes wit respect to the moving is 2.1. If the moving blade inlet and outlet aangles are equal then calculate the degree of reaction of the turbine.
In a Parson’s reaction turbine, the outlet angle of blade is 25°. Calculate the work done per second by the blades if the blade mean blade speed is 60 m/s and the absolute velocity of the steam leaving the nozzle is 120 m/s. The mass flow rate of steam is 0.1 kg per second.
