In this segment, we discuss the nozzles (goal is to increase velocity) and diffusers (goal is to decrease velocity), which are steady flow engineering devices. We also solve 2 example problems. The first problem is for steam entering the nozzle as a superheated vapor and exiting as saturated water and saturated vapor mixture and requires visiting the steam tables (A-5 and A-6 in Appendix 1 Cengel). The second problem is for air going through an adiabatic nozzle and requires visiting the air tables (A-17E in Appendix 2 Cengel).
