Which of these is the continuity equation for an axisymmetric flow? |
| A. | V<sub> </sub>cot u2061 + ( frac { (V_ )}{ } ) + V<sub> </sub> ( frac { ( )}{ } ) = 0 |
| B. | 2 V<sub>r</sub> + V<sub> </sub>cot u2061 + ( frac { (V_ )}{ } ) + V<sub> </sub> ( frac { ( )}{ } ) = 0 |
| C. | 2 V<sub>r</sub> + V<sub> </sub>cot u2061 = 0 |
| D. | ( frac {1}{r{^2}} frac { }{ r} ) (r<sup>2</sup> V<sub>r</sub>) + ( frac {1}{r sin } frac { }{ } )( V<sub> </sub>sin u2061 ) + ( frac {1}{r sin } frac { ( V_ )}{ } ) = 0 |
| Answer» C. 2 V<sub>r</sub> + V<sub> </sub>cot u2061 = 0 | |
