The liquid volume of the activated sludge aeration tank for Perryville without additional information and calculations based on the specific design parameters and wastewater characteristics.

Without knowing the assumptions or data provided in Example 16-1, it is not possible to accurately estimate the liquid volume of the completely mixed activated sludge aeration tank for Perryville.

In general, the design of a wastewater treatment plant involves a complex set of calculations and considerations, taking into account the specific characteristics of the influent wastewater, the desired effluent quality, the type and size of treatment units, and other factors.

The design of the activated sludge process, in particular, requires knowledge of parameters such as the sludge age, hydraulic retention time, and mixed liquor suspended solids concentration, which can affect the performance and sizing of the aeration tank.

Given the design flow rate of 34,560 m³/d and the influent BOD of 188 mg/L, one approach would be to estimate the required volume of the aeration tank based on the hydraulic retention time (HRT) and the mixed liquor suspended solids (MLSS) concentration.

Assuming an MLVSS of 2,000 mg/L, a typical MLSS concentration for activated sludge systems, and a desired HRT of 8-12 hours, the required volume of the aeration tank would be between 2,743 and 4,115 m³.

The correct answer is b. When traffic volumes are highest.

A tunnel requires its highest level of lighting when traffic volumes are highest to ensure safe passage for drivers. This is because high traffic volumes lead to reduced visibility due to the buildup of exhaust fumes, dust, and other pollutants in the tunnel. These pollutants can absorb or scatter the light, making it difficult for drivers to see clearly. Therefore, a higher level of lighting is required to compensate for the reduced visibility and ensure safe driving conditions.
However, it is important to note that lighting requirements may vary depending on the specific location, length, and design of the tunnel. Factors such as the width of the tunnel, curvature, gradient, and the presence of other structures or obstacles can affect lighting needs. For example, a shorter tunnel with minimal curves and gradients may require lower lighting levels than a longer tunnel with more complex design features.

Modulus of Rupture = 940.3 ksi, Apparent modulus of elasticity = 42,999 ksi.

Using the information provided, we can calculate the modulus of rupture (MOR) and the apparent modulus of elasticity (MOE) of the wood lumber.

The equations to calculate these values are:

[tex]MOR = (3FL)/(2bd^2)[/tex]

[tex]MOE = (FL^3)/(4bd^3δ)[/tex]

Where:

F = maximum load (240 kips)

L = span (4 ft or 48 in.)

b = width of the lumber (4 in.)

d = depth of the lumber (unknown)

δ = deflection at mid-span (2.4 in.)

To solve for d, we can use the ratio of the width to the depth of the lumber, which is assumed to be 1:2 based on the given orientation. Therefore, we have:

b/d = 1/2

d = 2b

Substituting the known values, we get:

d = 2b = 2(4 in.) = 8 in.

Now we can calculate the MOR and MOE:

[tex]MOR = (3FL)/(2bd^2) = (3*240 kips*48 in.)/(2*4 in.*8 in.^2) = 940.3[/tex] ksi

[tex]MOE = (FL^3)/(4bd^3δ) = (240 kips*(48 in.)^3)/(4*(4 in.)*(8 in.)^3*(2.4 in.)) = 42,999 ksi[/tex]

Therefore, the modulus of rupture of the wood lumber is 940.3 ksi and the apparent modulus of elasticity is 42,999 ksi.

Note that the units of MOR and MOE are both in ksi (kips per square inch), which is a common unit used for strength and stiffness of materials.
