Question $17$

A $7\mathrm{.}1k\frac{g}{m}in$ stream of refrigerant R$-32$ vapor enters a melter at $40C$ and $23\mathrm{.}5$ atm and exits as liquid at constant temperature and pressure. A $9\mathrm{.}0k\frac{g}{m}in$ stream of ice

and water enters the melter at $0C$ and $1$ atm and exits as liquid at $5C$ and $1$ atm $.$ Calculate the ice and water inlet composition.

The inlet ice percentage is

Express the result to three significant figures.
