Steam enters a converging nozzle at 3.0 mpa and 500°c with a ney at 1.8 mpa. for a nozzle exit area of 32 cm^2, determine the exit ver exit mach number if the nozzle: pa and 500°c with a negligible velocity, and it exits cm, determine the exit velocity, mass flow rate, and (a) (b) is isentropic has an efficiency of 94 percent

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
