A nozzle is so shaped that the average flow velocity changes linearly from 1.5 m/s at the beginning to 15 m/s at its end in a distance of 0.375 m. The magnitude of the convective acceleration (in m/s²) at the end of the nozzle is _________
-
- 5.5 m/s²
- 55 m/s²
- 45 m/s²
- 4.5 m/s²
Correct Option: B
54
| Convective acceleration = a | + v | + | ||||
| ∂x | ∂y | ∂δ |
| = 1.5 × | = 54 m/s² | |
| 0.3375 |
