Degree of Reaction for Turbine Solution

STEP 0: Pre-Calculation Summary

Formula Used

Degree of Reaction = (Enthalpy Drop in Rotor)/(Enthalpy Drop in Stage)
R = (ΔE_{rotor drop})/(ΔE_{stage drop})
This formula uses 3 Variables

Variables Used

Degree of Reaction - Degree of reaction is defined as the rate of energy transfer by virtue of change of static pressure to the total energy transfer.
Enthalpy Drop in Rotor - (Measured in Joule) - Enthalpy Drop in Rotor is the decrease in the amount of energy.
Enthalpy Drop in Stage - (Measured in Joule) - Enthalpy drop in stage is the decrease in the amount of energy.

STEP 1: Convert Input(s) to Base Unit

Enthalpy Drop in Rotor: 14 Kilojoule --> 14000 Joule (Check conversion here)
Enthalpy Drop in Stage: 56 Kilojoule --> 56000 Joule (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

R = (ΔE_{rotor drop})/(ΔE_{stage drop}) --> (14000)/(56000)

Evaluating ... ...

R = 0.25

STEP 3: Convert Result to Output's Unit

0.25 --> No Conversion Required

FINAL ANSWER

0.25 <-- Degree of Reaction

Ideal Turbine Work given Pressure Ratio

Go Turbine Work = Specific heat at constant pressure*Turbine Inlet Temperature*((Turbine Pressure Ratio^((Heat Capacity Ratio-1)/Heat Capacity Ratio)-1)/(Turbine Pressure Ratio^((Heat Capacity Ratio-1)/Heat Capacity Ratio)))

Efficiency of turbine in actual gas turbine cycle

Go Efficiency of Turbine = (Turbine Inlet Temperature-Turbine Exit Temperature)/(Turbine Inlet Temperature-Isentropic Turbine Exit Temperature)

Efficiency of Turbine in actual Gas Turbine Cycle given Enthalpy

Go Efficiency of Turbine = (Turbine Inlet Enthalpy-Turbine Exit Enthalpy)/(Turbine Inlet Enthalpy-Isentropic Turbine Exit Enthalpy)

Turbine Work in Gas Turbine given Temperature

Go Turbine Work = Specific heat at constant pressure*(Turbine Inlet Temperature-Turbine Exit Temperature)

Degree of Reaction for Turbine

Go Degree of Reaction = (Enthalpy Drop in Rotor)/(Enthalpy Drop in Stage)

Turbine Work given Enthalpy

Go Turbine Work = Turbine Inlet Enthalpy-Turbine Exit Enthalpy

Degree of Reaction for Turbine Formula

Degree of Reaction = (Enthalpy Drop in Rotor)/(Enthalpy Drop in Stage)
R = (ΔE_{rotor drop})/(ΔE_{stage drop})
