Hoof nippers allow you to trim around the hoof wall until the horse's foot is the proper length. Every barn or stable should be equipped with at least one of these essential horseshoeing tools.
Asked by: Anthony Matarazzo. Mach number is a common 'ratio' unit of speed when one is talking about aircrafts. By definition, Mach number is a ratio of the speed of a body (aircraft) to the speed of sound in the undisturbed medium through which the body is traveling.
The local speed of sound, and thereby the Mach number, depends on the condition of the surrounding medium, in particular the temperature and pressure. The Mach number is primarily used to determine the approximation with which a flow can be treated as an incompressible flow. The medium can be a gas or a liquid.
