Question
The annual average rainfall in a tropical city is 1000 mm. On a particular rainy day (24-hour period), the cumulative rainfall experienced by the city is shown in the graph. Over the 24-hour period, 50% of the rainfall falling on a rooftop, which had an obstruction-free area of , was harvested into a tank. What is the total volume of water collected in the tank in liters?
Correct answer
(C) 7,500
Solution
From the graph, the cumulative rainfall at the end of 24 hours is 300 mm.
Total depth of rainfall = .
Area of the rooftop = .
Total volume of water falling on the rooftop = .
Since 50% of this water is harvested:
Volume collected = .
Converting to liters ():
Volume in liters = .
Total depth of rainfall = .
Area of the rooftop = .
Total volume of water falling on the rooftop = .
Since 50% of this water is harvested:
Volume collected = .
Converting to liters ():
Volume in liters = .
