A $2 \mathrm{~m}^{3}$ biogas plant is to be operated using cow-dung as feedstock. The cow-dung is mixed with water in proportion of 1: 1 (by weight) to form a slurry of density $1090 \mathrm{~kg} \mathrm{~m}^{-3}$. The yield of biogas is $0.036 \mathrm{~m}^{3} \mathrm{~kg}^{-1}$ of cow-dung. If the hydraulic retention time is 40 days, volume of the digester of the biogas plant will be____________ $\mathrm{m}^{3}$
