Question
The ideal efficiency of simple gas turbine cycle principally depends on:Group of answer choicesMinimum cycle temperaturePressure RatioMaximum cycle temperatureAll of the above
Solution
The ideal efficiency of a simple gas turbine cycle principally depends on all of the above. This includes the minimum cycle temperature, the pressure ratio, and the maximum cycle temperature.
Here's why:
-
Minimum cycle temperature: The lower the minimum temperature (the temperature at which the gas enters the turbine), the less work the turbine has to do to compress the gas. This increases the efficiency of the turbine.
-
Pressure ratio: The pressure ratio (the ratio of the pressure of the gas at the end of the compression to the pressure at the beginning of the compression) also affects the efficiency. A higher pressure ratio means that the turbine can extract more work from a given amount of gas, which increases the efficiency.
-
Maximum cycle temperature: The higher the maximum temperature (the temperature at which the gas leaves the turbine), the more work the turbine can extract from the gas. This increases the efficiency of the turbine.
Therefore, all of these factors - minimum cycle temperature, pressure ratio, and maximum cycle temperature - play a role in determining the ideal efficiency of a simple gas turbine cycle.
