Question 2Gas Turbine - Assistant Engineer
70% to passIn a gas turbine, the air charge is permitted to be compressed adiabatically by what factor, process, or condition?
ARapid heat transfer
BLow-compression ratio
CInterstage cooling
DSpeed of the process
AI Explanation
The correct answer is D) Speed of the process. In a gas turbine, the air charge is permitted to be compressed adiabatically, meaning that the compression process occurs without heat transfer to or from the surrounding environment. The speed of the compression process is a key factor that determines the degree of adiabatic compression that can be achieved. The other answer choices are incorrect because: A) Rapid heat transfer would mean the process is not adiabatic; B) Low-compression ratio would not maximize the efficiency of the adiabatic compression; and C) Interstage cooling is not a factor in the initial adiabatic compression stage.
