Hint Answer

7. All energy relations satisfy mamatical condition in rmodynamics.

True False

True

All rmodynamic energy relations satisfy mamatical condition of being a set of continuous variables. They are a function of state variables mselves.

Hint Answer

8. The performance of a flow device is expressed in terms of _____

Adiabatic efficiency Isentropic efficiency Thermal efficiency Mechanical efficiency

Isentropic efficiency

The performance of a flow device is expressed in terms of its isentropic efficiency. The actual performance of device is compared with that of its isentropic device. It happens at same inlet and exit conditions.

Hint Answer

9. Isentropic efficiency is defined as ____

The power output of actual turbine/ power output if the turbine were isentropic The power input of actual turbine/ power output if the turbine were isentropic The power output of actual turbine/ power output if the turbine were adiabatic The power output of actual turbine/ power output if the turbine were polytropic

The power output of actual turbine/ power output if the turbine were isentropic

The performance of a flow device is expressed in terms of its isentropic efficiency. The actual performance of device is compared with that of its isentropic device. It happens at same inlet and exit conditions.
