Design of a community biogas plant for a village consisting of 114 families, each family consisting of 5 persons (adults). Two children are equivalent to one person. Village survey report gives the following information’s about cattle’s Cows 185 (10 kg/day); Oxes 135 (12 kg/day); Buffalo 75 (15 kg/day) ; pig 10 ( 3 kg/day); Gas produced from 1 kg of gobar in winter and summer 42 litre and 55 litre. Gas required for cooking/person/day = 0.227 m3 ,Gas required for lighting 100 cp lamp per hour = 0.126 m3 Each family is allotted 2 lamps, which would burn 3 hours daily, Density of slurry 1090 kg/m3 and retention time 35days. Design the following parameters (i) gas required for cooking& Lighting (ii) Diameter of digester Diameter d=
