| 41. | For an irrotational flow, the flow velocity can be described as the gradient of a velocity potential.
|
| 42. | In fluid dynamics, a flow is considered incompressible if the divergence of the flow velocity is zero.
|
| 43. | By reducing flow velocity to limit solids being transported along with fast flowing liquid, separation can occur.
|
| 44. | If the trailing edge has a non-zero angle, the flow velocity there must be zero.
|
| 45. | By Bernoulli's principle, this increases the flow velocity of the water, thus reducing pressure.
|
| 46. | Here " ? " is the mean flow velocity below steady in this reference frame ).
|
| 47. | The steps of the spillway greatly reduce the kinetic energy of the flow and therefore reduce flow velocity.
|
| 48. | Incompressible flow implies that the density remains constant within a parcel of fluid that moves with the flow velocity.
|
| 49. | With large areas of impervious surfaces, airports must employ methods to collect runoff and reduce its flow velocity.
|
| 50. | The Boussinesq approximation for water waves takes into account the vertical structure of the horizontal and vertical flow velocity.
