    Generating Power given Calorific Values & Densities

    Hi, Q: Sludge gas is 70% methane with a calorific value of 22MJ/m^3. Work out how much oxygen is required as m^3 of air to generate a 100 MWh of power if the density of the sludge gas is 1.03kg/m^3 and the density of air 1.3kg/m^3 which is also 23% by weight oxygen. This is a practice question...
