$3.(15$ points$)$ Saturated liquid $R-134$ a enters an adiabatic nozzle at $600$ kPa with a velocity of $5\frac{m}{s},$ and leaves as a subcooled liquid at $18C.$

Please include a picture.

Don't forget: $1k\frac{J}{k}g=1000\frac{m^2}{s^2}$

Set up the energy balance and determine the exit velocity of the refrigerant, in $\frac{m}{s}.$
