(Nov/Dec-2009)Īns: The stagnation state of a fluid is defined as the state of the fluid attained, when the flow is isentropically decelerated to zero velocity at zero elevation. Define stagnation state and stagnation enthalpy. Īns: Mach number is defined as the ratio of local velocity of fluid to local sonic velocity at the same point.Ĥ. The velocity of sound in air is calculated by a RT. ![]() ![]() What is the velocity of sound in air at 27oC? (May 2009)Īns: The velocity of sound is defined as the velocity at which pressure waves are transmitted through the medium. Examples are incompressible fluid – water, oil and compressible fluid – air, hydrogen.Ģ. The compressibility factor is one for incompressible fluid and is less than one for compressible fluid. (Nov/ Dec- 2006)Īns: Density is constant for incompressible fluid flow and it is variable for Distinguish between compressible fluid and incompressible fluid flow.
