It is the ratio of inertial forces acting on the fluid to the surface tension acting forces. ‘D’ is characteristic length,  fluid density,  fluid velocity and  is surface tension acting on the fluid. |

Weber Number
Reynolds Number
| Reynolds number is ratio of the inertial forces in a flowing fluid to the viscous forces acting on the fluid. |
Mach Number
| Mach number for a moving object is the ratio of speed of that object moving in a fluid (u) to the speed of sound in the fluid (a). |
froude number
| Fraude number is ratio of inertial force to gravitational force. It is a measure for resistance to the motion of a body moving through water. ‘u’ is velocity of the moving object and ‘L’ is characteristic length of that object. |
What is Geology?
Geology is the study of the Earth, the materials of which it is made, the structure of those materials, and the processes acting upon them. It includes the study of organisms that have inhabited our planet. An important part of geology is the study of how Earth’s materials, structures, processes and organisms have changed over time.
