Unpublished paper, 'On the true theory of pressure as applied to elastic fluids' by Robert Moon

Description

Moon aims to show that in elastic fluids in motion, or tending to move, it is not generally true that the pressure depends solely on the density, as is assumed in the ordinary theory of the motion of elastic fluids; and to show that, within certain limits and under certain circumstances, pressure may be transmitted instantaneously from one point of an elastic fluid to other points situated at finite distances from the first, before any change has been effected in the density of the intermediate fluid, in a manner analogous to that in which, in the theory of dynamics as applied to rigid bodies, force is assumed to be propagated instantaneously from one point to another.
