Hot, moist outside air passes over a cooling coil, from which it exits in a saturated state at p=14.7lbf/in^2 and T=65F. The air is then mixed adiabatically with room air at p=14.7lbf/in^2, T=75F, phi=25%. The mixing process occurs at constant pressure. The dry air mass flow rate leaving the cooling coil is 250lbm/h, and the dry air mass flow rate entering the mixing chamber from the room is 750 lbm/h. Using the psychometric chart, determine the following:

i) the humidity ratio leaving the cooling coil

ii) the humidity ratio leaving the room

iii) the humidity ratio leaving the mixing chamber

iv) the final mixed air temperature (F)

v) the final mixed air relative humidity
