Q 9. Design a Biogas system for cooking for a family of six members by determining the estimation of total gas required, amount of feedstock (or dung), required and the number of animals required to have feedstock of a given amount. Consider the following parameters for system design About 350-450 liters of biogas required per day per person for cooking (in engine about 450 liters/hp/hour of biogas is required) Average production of dung per animal per day: o Cow- 10 kg/day Bullock - 14 kg/day o Buffalo - 15 kg/day

Q 9. Design a Biogas system for cooking for a family of six members by determining the
estimation of total gas required, amount of feedstock (or dung), required and the number of
animals required to have feedstock of a given amount. Consider the following parameters for
system design
About 350-450 liters of biogas required per day per person for cooking (in engine
about 450 liters/hp/hour of biogas is required)
Average production of dung per animal per day:
Cow- 10 kg/day
Bullock -
14 kg/day
o Buffalo - 15 kg/day
Page 2 of 3
1000 liters of gas is equivalent to 1 m' of gas.
Average gas production from dung is about 40 liters/kg of fresh dung.
Retention period of dung slurry in digester is 50 days.
