Final answer:
Exhaust gas temperature (EGT) on a turbine engine indicates the temperature of the gases exiting the engine after combustion. It is obtained using pyrometers or thermocouples placed in the exhaust system to measure the temperature of the gases.
Step-by-step explanation:
Exhaust gas temperature (EGT) on a turbine engine indicates the temperature of the gases exiting the engine after combustion. It is an important parameter for monitoring the engine's performance and ensuring efficient operation. EGT is obtained using pyrometers or thermocouples placed in the exhaust system to measure the temperature of the gases.
