# Learn the tricks to design a circular sedimentation tank

This construction video tutorial shows the step-by-step process for creating the design of a sedimentation tank having rectangular shape.

In this video, the proper solution is provided to solve out the following problem :-

Problem: Create the design of a circular sedimentation tank based on the capacity of 10000 ??^3/day. Water will remain for 2 hours in tank (detention period).

Here, design means to determine the diameter and the depth of the height of the tank. The capacity of the tank should be determined in volume.

The capacity is 10000 cubic meter per day and 1 day is equal to 24 hours. So, just divide 10000 by 24 and multiply with 2 i.e.

1000/24 x 2 (as water remains for 2 hours) = 833.34, the volume of water

To find out the volume of circular tank, use the following formula :-

Volume = area of base x height

Volume = pD2/4 x H

As the value of height is unknown, just assume 3 meter for it

So, 833.34 = pD2/4 x 3
