| 1. | The velocity at the stagnation points is zero .
在停滞点处，流速为零。 |
| 2. | Rates of flow are represented by the slopes .
流速由斜率模拟。 |
| 3. | The pressure is p, the velocity is v .
压力为P，流速为V。 |
| 4. | A low rate is enough to prevent flushing of reductants .
缓慢的流速足以防止还原剂的散失。 |
| 5. | The velocity in the intake is not equal to the stream velocity .
进口的流速不等于河水流速。 |
| 6. | The velocity of the fluid is inversely proportional to the spacing of the steamlines .
流体的流速与流线的间距成反比。 |
| 7. | The river was not high, so there was not more than a two-or three-mile current .
河里的水不大，所以流速也不过二三英里。 |
| 8. | At some higher velocity the ripples or dunes disappear and the bed becomes flat .
流速增大时，沙纹、沙垄消失，河床变平。 |
| 9. | The hydrometric pendulum is sometimes used to determine flow velocities in open channels .
测流速的摆锤有时用于确定明渠中的流速。 |
| 10. | The maximum surface velocity near the center is somewhere between one and two feet per day .
靠近中心的最大表面流速为每天大约12英尺。 |
