Degree of Reaction for Turbine Solution

Follow our step by step solution on how to calculate Degree of Reaction for Turbine?

FIRST Step Consider the formula

R = \frac{ΔE rotor drop}{ΔE stage drop}

Next Step Substitute values of Variables

∴

R = \frac{14KJ}{56KJ}

Next Step Convert Units

∴

R = \frac{14000J}{56000J}

Next Step Prepare to Evaluate

∴

R = \frac{14000}{56000}

LAST Step Evaluate

∴

R = 0.25
