The ratio of velocity of fluid in an undisturbed stream to the velocity of sound wave is known as Mach number.
-
The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly contracted to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden contraction, assuming coefficient of contraction as 0.62, is

All the gases are considered to have compressible flow and all the liquids are considered to have incompressible flow.
