Question
In an attempt to conserve water and to be awarded LEED (Leadership in Energy and Environmental Design) certification, a 20.0x
103 L cistern has been installed during construction of a new building.
The cistern collects water from an HVAC (heating, ventilation and air-conditioning) system that is designed to provide 100 x 105
ft/min air at 22.0°C and 40.0 % relative humidity after converting it from ambient conditions (35.0 °C, 86.0 % relative humidity).
The collected condensate serves as the source of water for lawn maintenance. Assume P-1 atm.
