6. Solve the following using the psychrometric chart. A filter-dryer exhaust is saturated air at 70F. This air is to be conditioned and then recycled back to the filter. To do this, the filter exhaust is first heated in a heat exchanger and then passed through an adiabatic humidifier where it reached 80%RH at the chamber exit. The chamber exit air is then reheated in a second heat exchanger to the final desired conditions of 130F dry bulb and 96F wet bulb, after which it is fed into the filter-dryer. a. What is the temperature of the recycled water fed to the humidifier spray nozzle? b. What humidifier exit temperature and humidity can be expected for the air? c. How much make-up water per hour wilfbe needed for the humidifier, if the volumetric exit is 5000 CFM? d. What is the heat transferred in the second heat exchanger
