Determine the daily volume of methane and total gas produced in an anaerobic
digester if the biosolids flow rate is 200 m³/d and the COD concentration going into
the reactor is 5,000 g/m³. Assume yield is 0.05 g VSS/g COD, that there is 90%
COD removal, and that methane is 50% of the total gas volume. Assume that actual
gas production at the operating temperature is 0.4 L of CH4 per g of COD. Express
your answer in m³/d and round to the nearest integer.

yield of bacteria that use the organic molecule butyrate (C4 H7O2¯) as their

- In this question, we are going to learn about the gravity model. As discussed in class, an alternative and frequent way to model the demand is doing it in 4 steps: Generation/Attraction, Distribution, Mode choice, and Route choice. In the generation/attraction step, we estimate the number of trips that depart and arrive from each zone, in a similar way as we studied generation in the lectures. The idea of the distribution step is, taking the generation and attraction numbers as known, estimate the number of people going from each zone to each zone. Let's be precise: Consider that you know O₂ for every zone i, representing the number of users that have i as their origin. Similarly, you know Dj, representing the number of users that have j as their destination. We want to estimate Mij, i.e., the number of users going from i to j. The matrix Marrow_forward= a2+ Assume an origin is connected to a destination with two routes. Assume the travel time of each route has a linear relationship with the traffic flow on the route (t₁ = α₁ + b₁x₁ ; t₂ b2x2). Determine under what condition (e.g. a relationship among the parameters of the performance functions) tolling cannot reduce the total travel time of the two routes.arrow_forwardA suburb has 2000 households.
