Generally, frictional losses are more predominant for the machines being not 100% efficient. This friction leads to the loss of energy in the form of heat, into the surroundings. Some of the supplied energy may be utilised to change the entropy (measure of randomness of the particles) of the system.

Answer:
Exit velocity
m/s.
Explanation:
Given:
At inlet:

Properties of steam at 100 bar and 600°C

At exit:Lets take exit velocity 
We know that if we know only one property inside the dome then we will find the other property by using steam property table.
Given that dryness or quality of steam at the exit of nozzle is 0.85 and pressure P=80 bar.So from steam table we can find the other properties.
Properties of saturated steam at 80 bar

So the enthalpy of steam at the exit of turbine



Now from first law for open system

In the case of adiabatic nozzle Q=0,W=0

m/s
So Exit velocity
m/s.
