Question

in a rain water harvesting system the rainwater from a roof of 22mx20m drains into a cylindrical tank having diameter of base 2m and height 3.5m if the tank is full fund the rainfall in cm

Answer 1

Answer:

Step-by-step explanation:

Volume of roof = 22×20×h (l×b×h)

Height of roof = Height of rain

Volume of cylinder = πr^2h

= 22/7×(1×1×3.4)

Volume of water of roof = volume of cylinder

22×20×h = 22/7×1×1×3.5

h = 3.5/7×20

h = 1/40

h = 0.025m

h = 2.5cm

Therefore, height of rain is 2.5cm.
