1. Nevertheless, understanding potential flow is important in many branches of fluid mechanics. 2. Potential flow finds many applications in fields such as aircraft design.3. The Prandtl Glauert transformation is a linearized approximation of compressible, inviscid potential flow . 4. Disproportional flow can lead to turbulent and hydraulic instability and potential flow short-circuiting. 5. However, potential flows also have been used to describe compressible flows. 6. Here depression, despair and wasted human potential flow through the streets. 7. The solution to potential flow around a circular cylinder is doublet, and a vortex. 8. This is known as the potential flow theory that works remarkably well in practice. 9. This implies that a potential flow is an irrotational flow. 10. This has direct consequences for the applicability of potential flow .
