In an attempt to conserve water and to be awarded LEED (Leadership in Energy and Environmental Design) certification, a 15.0 x 10° 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 1.00 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.
