A house that measures 15 m long by 9 m wide at the drip line of
the roof is in an area receiving 304 mm of rain a year. How much
rainfall can realistically be collected off that roof in an average
year?
Given: • Area of roof = 15 m x 9 m • Average rainfall in a year
= 304 mm • Runoff coefficient = 0.80
Calculate the volume of water collected and the weight of
collected water per runoff.
