Physics Asked on June 27, 2021
Bernoulli’s principle states that, in a steady, incompressible, inviscid flow, the sum of all forms of mechanical energy in a fluid along a streamline is the same at all points on that streamline. This requires that the sum of the fluid’s kinetic energy, gravitational potential energy, and internal energy (i.e. pressure-volume energy) remains constant.
Real fluids are compressible and have viscosity.
What are the common scenarios given in literature or observed in everyday life that produce a fluid flow due to only a change in the fluids kinetic energy? This question supposes that it is possible. If it is not possible, can you explain why not? (E.g., if the kinetic energy changes then so too must the pressure-volume energy because [reasons])
