Two streams are mixed in an adiabatic mixer, as shown in the figure. It is known that: • Sream 1 is saturated liquid/saturated vapour mixture at 1 bar with flow rate 1.19 kg/s and quality 0.20 • Stream 2 is superheated vapour at 1 bar and 430°C • Stream 3, the product stream, is a saturated liquid/saturated vapour mixture at 1 bar with quality 0.94 Neglect kinetic and potential energy changes and calculate the mass flow rate of the superheated vapour stream, in kg/s.

Fluid Kinematics

The branch of science that deals with objects which are either in motion or stationary are studied under the branch of classical mechanics. Fluid mechanics is a subcategory of classical mechanics that deals with the behavior of fluids at rest (fluid statics) or in motion (posing some velocity). In fluid kinematics, studies focus on the associated motion of fluid particles or groups of particles, and its associated parameters like displacements, velocity, and acceleration without concerning about the forces that caused the motion. All the laws of classical mechanics are applied in the study of fluid kinematics.
