WebFor incompressible steady laminar inviscid flows, Bernoulli’s equation is: This equation relates the flow velocity u to the driving pressure P and the potential energy associated with any other time-independent conservative forces acting on the fluid. The SI (mks) units of this equation are J/kg, meaning the equation expresses a kinetic ... WebUsing Bernoulli's equation, the pressure coefficient can be further simplified for potential flows (inviscid, and steady): = where u is the flow speed at the point at which pressure coefficient is being evaluated, and Ma is the Mach number: the flow speed is negligible in comparison with the speed of sound.For a case of an incompressible but viscous fluid, … lithonia lighting closet light
What is the relation between incompressible flow and laminar flow?
