Solutions

Expert Solution

I have solved all the parts except the last part.You can find the work done by the turbine from the steady flow energy equation in first part where the heat transfer will be zero and change in potential energy will also be equal to zero.Hence work done is equal to sum of change in enthalpy and change in kinetic energy.Just put all the values.
