You cool, and partially condense, $200$ lbm$/$hr of a saturated vapor containing $65$ wt$\%$ NH$3,35$ wt$\%$ water vapor, at $160\backslash$deg F and $1$ atm by passing it through a heat exchanger, removing $75,000$ BTU$/$hr of heat. Determine the mass flow rate, fraction vapor, and composition of the vapor and liquid after the heat exchanger.
