Mass flow rate with mach number

WebRelative Mach Number. Firstly, high relative Mach numbers in a compressor imply a high mass flow per unit area, which leads to a more compact ... At lower mass flow rates, when the compressor is closer to stall, the shock structure is … Web21 de jul. de 2024 · Mass Flow Rate If the fluid initially passes through an area A at velocity V, we can define a volume of mass to be swept out in some amount of time t. The volume v is: v = A * V * t A units check gives area x length/time x time = area x length = volume. The mass m contained in this volume is simply density r times the volume. m = r * A * V * t

If the flow has attained the sonic condition (M=1) at a particular area A then increasing that area will indeed increase the mass flow rate but the increase of area will not increase the Mach number at that area …

As a general example of how dimensionless numbers arise in fluid mechanics, the classical numbers in transport phenomena of mass, momentum, and energy are principally analyzed by the ratio of effective diffusivities in each transport mechanism. The six dimensionless numbers give the relative strengths of the different phenomena of inertia, viscosity, conductive heat transport, and diffusive mass transport.
