Refrigerant $134$a flows at steady state through a horizontal tube having an inside

diameter of $2-in.$ The refrigerant enters the tube with a quality of $0\mathrm{.}2,$ temperature

of $68F,$ and velocity of $25f\frac{t}{s}.$ The refrigerant exits the tube at $95$ psia as a

saturated liquid. Determine $($a$)$ the mass flow rate of the refrigerant $($in $k\frac{g}{s}),$ and

$($b$)$ the velocity of the refrigerant at the exit $($in $f\frac{t}{s}).($Hint: same as above. Obtain

specific volumes from NIST, calculate using given quality and use that to calculate

mass flow rate$).$
