The Mach number for a body moving through a fluid with velocity V is defined as V/c where c is the speed of sound in the fluid. This dimensionless parameter is usually considered to be important in fluid dynamics problems when its value exceeds 0.3.
What would be the velocity of a body at a Mach number of 0.3 if the fluid is
(a) air at standard atmospheric pressure and 10 °C,
(b) water at the same temperature and pressure?
