Homework Statement
A very simplified schematic of the rain drainage system for a home is shown. Rain falling on the slanted roof runs off into gutter around the roof edge it then drains through downspouts into a main drainage pipe M below the basement which carries the water to an even larger pipe below the street. Apply the following:
1.)the downspouts have h1= 11m
2.)the floor drain has height h2=1.2m
3.)pipe M has radius 3cm
4.) the house has side width w=30 m and front length L=60 m
5.) all the water striking the roof goes through pipe M
6.) the initial speed of the water in a downspout is negligible
7.) the wind speed is negligible
At what rainfall rate, in centimeters per hour, will water from pipe M reach the height of the floor drain and threaten to flood the basement.
