In a city, the chemical formula of biodegradable fraction of municipal solid waste (MSW) is C
H
O
N. The waste has to be treated by forced-aeration composting process for which air requirement has to be estimated.Assume oxygen in air (by weight) = 23 %, and density of air = 1.3 kg/m
. Atomic mass: C = 12, H = 1, O = 16, N = 14.C and H are oxidized completely whereas N is converted only into NH
during oxidation.For oxidative degradation of 1 tonne of the waste, the required theoretical volume of air (in m
/tonne) will be (round off to the nearest integer)Your answerChoose one option.
