How to find pit capacity/ How many literes pit will store
(22/7)*r*r*h
r – radius of cement ring
h – height of rings
22/7 – pie value (3.14)
- To find out your pit capacity first you need to have radius of cement ring and height of all rings
- Substitute all the values in above formula you will get the capacity of pit.
- 1 feet cube area(1′ length * 1′ width * 1′ height) will store upto 28 ltrs of water.
- So multiply your pit cubic area with 28 and you will get your pit storage capacity in liters
- Above formula will work only if your tank shape is in round shape
