21. With these conditions, the wind velocity component perpendicular to the boundary remains unaffected by the pressure change. 22. Why does the parcel keep its initial horizontal velocity component but not its velocity in the PGF direction. 23. The velocity components , in the directions respectively, can be obtained directly from by differentiating with respect to. 24. Experimentally it is found that the velocity component of rotational flow is proportional to r ^ 2, therefore: 25. These problems do not exist in Stereoscopic PIV, which uses two cameras to measure all three velocity components . 26. The phase shifts measured from left and right apertures are combined to give the axial and lateral velocity components . 27. The elliptic equation is derived from the continuity equation wherein velocity components are expressed in terms of p _. 28. Variations of the line-of-sight velocity component cause tiny shifts in the star's spectrum. 29. This is the velocity component of the star's equatorial rotation along the line of sight to the Earth. 30. The space velocity components of this system are U = 141, V = 7 and W = 7.
