Fun With Math and Water

This is one of my summer projects.

  • North Wing: 24×60
  • South Wing: 23×48
  • Great Room: 26×26
  • Studio: 32×18
  • Garage: 40×60

Total area of roofs:  6096 sqft

Last Year’s Rainfall:  17.5 inches

SUPPLY (gallons) = INCHES OF RAINFALL X 0.623 X CATCHMENT AREA (sq ft of roof) X .90 (runoff coefficient for a metal or asphalt roof)

59,815.476 gallons of rain water to plan to try collect this coming winter.

Oy Vey!
