To solve this problem it is necessary to apply the concepts related to the adiabatic process that relate the temperature and pressure variables
Mathematically this can be determined as
Where
Temperature at inlet of turbine
Temperature at exit of turbine
Pressure at exit of turbine
Pressure at exit of turbine
The steady flow Energy equation for an open system is given as follows:
Where,
m = mass
= mass at inlet
= Mass at outlet
= Enthalpy at inlet
= Enthalpy at outlet
W = Work done
Q = Heat transferred
= Velocity at inlet
= Velocity at outlet
= Height at inlet
= Height at outlet
For the insulated system with neglecting kinetic and potential energy effects
Using the relation T-P we can find the final temperature:
From this point we can find the work done using the value of the specific heat of the air that is 1,005kJ / kgK
So:
Therefore the maximum theoretical work that could be developed by the turbine is 678.248kJ/kg

And I took the test, so take my word for it.</span>
After putting stuff through google and some calculators, I’d say the answer is C.
Answer:
Explanation:
Given that,
The angular velocity of a wave, 
The maximum displacement of the wave, A = 10 cm (let)
The maximum acceleration of the wave is given by :
Put all the values,
So, the maximum acceleration of the wave is equal to 
.
Answer:
Explanation:
So average velocity is calculated as
Hence in our given case total displacement would be 5 m as the car moves a distance 7m to 2m.
Time taken for this moment is given to be 3 seconds.
Hence substituting back we get the average velocity as
Hence this is the average velocity in this case.
