b) The argon kappa value is: 1.67 [/].
c) The argon kappa value is: 1.32 [/].
d) The argon kappa value is: 1.4 [/].
What is the gas constant value for argon?
a) The argon gas constant value is: 280.1 [J/kg*K].
b) The argon gas constant value is: 286.7 [J/kg*K].
c) The argon gas constant value is: 2,078.5 [J/kg*K].
d) The argon gas constant value is: 296.9 [J/kg*K].
What is the specific heat value for argon in [J/kg*K]?
a) The argon specific heat value is: 2,092 [J/kg*K].
b) The argon specific heat value is: 2,223 [J/kg*K].
c) The argon specific heat value is: 1,004 [J/kg*K].
d) The argon specific heat value is: 519 [J/kg*K].
What is the ideal Brayton Cycle efficiency dependent on?
a) The ideal Brayton Cycle efficiency is dependent on the compression ratio.
b) The ideal Brayton Cycle efficiency is dependent on the compression ratio and working fluid physical properties.
c) The ideal Brayton Cycle efficiency is dependent on the working fluid physical properties.
d) None of the above.
For the ideal Brayton Cycle, how does an increase in the working fluid mass flow rate for the fixed gas turbine inlet temperature
and compression ratio values impact the power output?
a) As the working fluid mass flow rate increases, the Brayton Cycle power output decreases accordingly.
b) As the working fluid mass flow rate increases, first the Brayton Cycle power output increases accordingly and then it
decreases.
c) As the working fluid mass flow rate increases, the Brayton Cycle power output increases accordingly.
d) The working fluid mass flow rate change has no impact on the power output.
