In an attempt to conserve water and to be awarded leed (leadership in energy and environmental design) certification, a 20,000-liter cistern has been installed during construction of a new building. the cistern collects water from an hvac (heating, ventilation, and air-conditioning) system designed to provide 2830 cubic meters of air per minute at 22°c and 50% relative humidity after converting it from ambient conditions (31°c, 70% relative humidity). the collected condensate serves as the source of water for lawn maintenance. estimate (a) the rate of intake of air at ambient conditions in cubic feet per minute and (b) the hours of operation required to fill the cistern.
