Brayton Cycle
1 / 10
The Brayton cycle is less efficient than the Carnot cycle because:
The Brayton cycle rejects heat to the atmosphere, unlike the Carnot cycle, which is fully reversible, reducing its efficiency
2 / 10
Increasing the turbine inlet temperature in a Brayton cycle:
Higher turbine inlet temperatures increase the work output and efficiency of the Brayton cycle.
3 / 10
The ideal Brayton cycle consists of how many processes?
The Brayton cycle includes isentropic compression, isobaric heat addition, isentropic expansion, and isobaric heat rejection.
4 / 10
The exhaust gases in a Brayton cycle are typically:
In an open Brayton cycle, exhaust gases are released to the atmosphere after expansion in the turbine.
5 / 10
In a Brayton cycle, the turbine work output is used to:
The turbine produces work, part of which drives the compressor, with the remainder as net work output.
6 / 10
Which component of the Brayton cycle adds heat to the working fluid?
The combustion chamber adds heat to the air at constant pressure in the Brayton cycle.
7 / 10
The efficiency of an ideal Brayton cycle depends on:
The efficiency of an ideal Brayton cycle increases with the pressure ratio across the compressor, as it affects the work output.
8 / 10
In an ideal Brayton cycle, the compression process is assumed to be:
The compression in an ideal Brayton cycle is isentropic (adiabatic and reversible), meaning no heat is transferred, and entropy remains constant.
9 / 10
What is the primary working fluid in a Brayton cycle?
Air is the primary working fluid in the Brayton cycle, as it is compressed and heated in gas turbines.
10 / 10
The Brayton cycle is commonly associated with which type of engine?
The Brayton cycle is the thermodynamic cycle used in gas turbine engines, where air is compressed, heated, and expanded to produce work.
