How to check if a flow is incompressible
WebLet us define “incompressibility” as a good approximation when the ratio δ ρ/ρ is much smaller than unity. To determine the conditions for this approximation we must estimate the magnitude of changes in density. Steady Flow In steady flow, the maximum change in pressure can be estimated from Bernoulli’s relation to be δp=ρu 2.
