Question

In a rain-water harvesting system, the rain-water from a roof of 22 m  20 m drains into a cylindrical tank having diameter of base 2 m and height 3·5 m. If the tank is full, find the rainfall in cm. Write your views on water conservation.

Answer 1

Answer:

2.5 cm

Step-by-step explanation:

volume of roof is equal to volume of Cylindrical tank

l × b × h = Π r^2 h

22×20×h = Π (1)^2 × 3.5

h = 1/40 m

or h = 2.5 cm

so the rainfall in cm is 2.5 cm

views on water conservation:

1. environment friendly

2. can be used in future

3. conservation of resources

any other relevant point
