Question

what is the flow of kinetic energy

Answer 1

A nozzle is a steady state flow device to create a high velocity fluid stream at the expense of its pressure. The objective of the device is to increase the flow velocity, hence kinetic energy cannot be ignored. nozzle is treated as adiabiotic
