9.Practical bio gas.

Aim: Getting knowledge about bio gas practically

Requirement: Calculator, Tape

Process:

·       First we want to measure the area of tank.

·       Then measure the height of tank.

·       Formula is     pie r2xh=Volume.

·       After this we will get volume of tank.

·       Then subtract height from volume of tank.

·       You will get the quantity of gas inside.

·       When we add hot water into biogas its gas quantity increases,4ltrs 70cm to 75cm

·       When its morning tanks height is75cm, in afternoon tanks height is increased to 80cm. (when we put 5kgs dung into biogas).

·       When we put 4ltrs of hot water in evening tanks height increased 2cm only because of low temperature.

Conclusion:      

·       Gas increases when temperature is high.

·       Water vapor also come with methane.

·       We want to separate water vapor from methane gas then only fire will fire continuously.

·       We want to note readings continually to make a conclusion on bio gas.
