B)False.......they travels at the same speed
To solve this problem it is necessary to apply the concepts of heat change and thermal efficiency.
The heat rate can be expressed under the function
Where,
m = Mass
Enthalpy at each state
Our values are given as,
From the tables of Enthalpy of Water at 200°C (Saturated liquid state)
At the same time for 80°C
Applying the equation of Heat,
Replacing,
Therefore the efficiency would be
Therefore the actual thermal efficiency of the turbine in percent is 0.0579.
