Where is this used?

What is the isentropic heat drop?

Malik said:   1 decade ago
The flow through nozzles is deemed as adiabatic i.e. isentropic, because heat doesn't find time to loss in space due to very high speed of fluid, but practically there should be some heat losses, isentropic heat drop represent our assumption i.e (s=constant) & heat drop represent the very actual case,

What is internal efficiency?

Bapun said:   10 years ago
Its answer in book is nozzle efficiency.

So how is the right answer?

Bhairabmondal. said:   10 years ago
It is called nozel efficiency.

Mvk said:   9 years ago
Is there any significance of internal efficiency in turbines?

Only stage efficiency and overall efficiency are calculated.

Engr Arshad jamali said:   9 years ago
It is also called as nozzle efficiency.

Vijay kumar said:   9 years ago
It's right answer is that nozzle efficiency.

Nayan Gogoi said:   8 years ago
It's Nozzle efficiency.
