41. Typically the transverse pressure gradient and thus may be styled as a free surface after separation. 42. A rapidly tightening pressure gradient north of the cyclone generated strong winds throughout coastal New England. 43. These aerodynamic separation processes depend upon diffusion driven by pressure gradients , as does the gas centrifuge. 44. The reason for this is that there is a larger pressure gradient across the aortic valve. 45. The pressure gradient force dictates that air will travel from regions of high to low pressure. 46. The smaller bubble size reduces the bubble pressure gradient and forms a much longer lasting foam. 47. There is a pressure gradient from the perimeter of the bowl or cup toward the center. 48. The pressure gradient force was neglected as it has significant effect only on the updraft in supercells. 49. This pressure gradient provides the centripetal force necessary for the circular motion of each parcel of air. 50. This analysis introduces the non-dimensional pressure gradient
