43.
The acceleration components of a fluid particle are denoted as
1. local tangential acceleration.
2. convective tangential acceleration.
3. local normal acceleration.
4. convective normal acceleration.
In a curved nozzle fitted to the end of straight pipeline carrying water under variable head, the acceleration component that are present would include
1. local tangential acceleration.
2. convective tangential acceleration.
3. local normal acceleration.
4. convective normal acceleration.
In a curved nozzle fitted to the end of straight pipeline carrying water under variable head, the acceleration component that are present would include

Convective tangential acceleration will be there because the magnitude of velocity changes along the nozzle.
Convective Normal acceleration will exist due to the change in the direction of velocity along the nozzle.
Because of a change in the magnitude of velocity at any point concerning time Local tangential will exist but Local Normal acceleration will be zero because the direction of velocity at any cross-section does not change concerning time.
Convective Normal acceleration will exist due to the change in the direction of velocity along the nozzle.

I think the correct answer is B. Because the curved nozzle streamlines are curved and tangential acceleration can not exist.
Tangential ----> Straight streamlines.
Normal ----> Curved streamline.
Local ----> Change with time.
Convective ----> Change with length.
Tangential ----> Straight streamlines.
Normal ----> Curved streamline.
Local ----> Change with time.
Convective ----> Change with length.
