The solution of the equations is a flow velocityIt is a vector fieldto every point in a fluid at any moment in a time interval it gives a vector whose direction and magnitude are those of the velocity of the fluid at that point in space and at that moment in time. At low pressures and temperatures Z is nearly equal to 100 whereas at higher pressures and temperatures it may range between 075 and 090. Fluid Mechanics Lecture 2 Compressible And Incompressible Flow And Flow Fluid Flow Fluid Mechanics Fluid ρ A dV ρ V dA AV dρ 0. . Compressibility becomes important for High Speed. APPLICABILITY AND DEFINITIONS. In case of incompressible flow the density ρ is constant and hence the integration of d P ρ is equal to P ρ. Fluid continuity equation. For the case of compressible flow the continuity equation and the Navier-Stokes equation must be augmented by the energy conservation equation as well as thermodynamic relations that spe...
