Heat Added in Gas Turbine Combustion Solution

STEP 0: Pre-Calculation Summary

Formula Used

Heat Added = Enthalpy after Combustion-Enthalpy before Combustion
Q = h₃-h₂
This formula uses 3 Variables

Variables Used

Heat Added - (Measured in Joule) - Heat added is the amount of heat added to a system.
Enthalpy after Combustion - (Measured in Joule) - Enthalpy after combustion is the increase in the enthalpy of fluid after adding heat.
Enthalpy before Combustion - (Measured in Joule) - Enthalpy before Combustion is the amount of energy contained by fluid after compression.

STEP 1: Convert Input(s) to Base Unit

Enthalpy after Combustion: 1700 Kilojoule --> 1700000 Joule (Check conversion here)
Enthalpy before Combustion: 310 Kilojoule --> 310000 Joule (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q = h₃-h₂ --> 1700000-310000

Evaluating ... ...

Q = 1390000

STEP 3: Convert Result to Output's Unit

1390000 Joule -->1390 Kilojoule (Check conversion here)

FINAL ANSWER

1390 Kilojoule <-- Heat Added

(Calculation completed in 00.020 seconds)
