Given,
Per day consumption of gas per person is liters
Thus, total gas to be produced per day
lites
liter cubic meter
Thus, total gas produced per day cubic meter
Total weight of slurry produced
cubic centi meter gram/cm 3
kilo gram per day
Retention Period is of days, thus the digester must be able to hold atleast days slurry
Volume of bio digester considering days retention
cubic meter
The average calorific calorific value of biogas is about MJ/m³
Thus, energy produced per day
Mj
Mj
Energy produced in a year
Mj
Mj Kj
Thus, Energy produced in a year in Kilo joules
Kilo Joules
Amount of solid dung
kilo gram per day
An average cow produce kilograms of dung
Thus, number of cow required
cows
cows
If more members are added, the requirement of cow dungwill increase as energy requirement will increase, thereby the size of biodigester and slurry input will also increase.
with per person daily consumption of liter gas , the additional requirement of gas will be
liters
Total increased gas requirement per day would be cubic meter, there by increasing the tota gas requirement from cubic meter to cubic meter
