Answer:
Temperature at the exit =
Explanation:
For the steady energy flow through a control volume, the power output is given as
Inlet area of the turbine =
To find the mass flow rate, we can apply the ideal gas laws to estimate the specific volume, from there we can get the mass flow rate.
Assuming Argon behaves as an Ideal gas, we have the specific volume
as
for Ideal gasses, the enthalpy change can be calculated using the formula
hence we have
<em>Note: to convert the Kinetic energy term to kilojoules, it was multiplied by 1000</em>
evaluating the above equation, we have
Hence, the temperature at the exit =
