Which of these is not an assumption used in modeling an idea

Which of these is not an assumption used in modeling an ideal turbine? A. Nogligible extenal work done B. Nogligible change in kinetic energy D. Negligible heat translor with the surroundings E. Nogligible change in enthalpy

Solution

1) E)negligible change in enthalpy, The enthalpy change is significant in turbines

2)E)negligible change in enthalpy, The enthalpy change is significant in turbines

3)A) negligible external work done, The external work done is significant in this process

4)E)negligible change in enthalpy, The enthalpy change is significant in turbines
