A treatment plant being designed for cynusoidal city requires an
equalization basin to even outflow and BOD variations.The average
daily flow is 0.400m^3/s.The following flows and BOD5 have been
found to be typical of the average variation over a day.What volume
equalization basin is required to provide for a uniform outflow
equal to the average daily flow?Assume the flows are hourly
averages and that an addition of 25% to the estimated volume will
be provided to account for contingencies.

4. Explain the relation between surface roughness and effective
bondable area on the example of a cosine wave (sketch the surface
and explain how to model the surface area). The cosine waves
amplitude is 25% of the wave length. How many percent larger is
this area as compared to being totally flat (amplitude is 0% of
wave length). Base your calculations on the numeric length integral
for the waves length.

A CM basin with a volume of 475 m3 receives a flow of
2000 m3 d−1. The basin has a dead volume of
42 m3. Find the effluent tracer curve if a mass of 5 g
of tracer is added instantaneously to the influent. Also plot the
effluent tracer curve for the reactor without dead volume.

Determine the terminal settling velocity of a particle having a
density of 2540 kg/m3 and a diameter of 10 mm in water having a
temperature of 10C. You may assume that the particle is a perfect
sphere (shape factor = 1). What would be the settling velocity for
the same particle if the water temperature decreased to 5C?

The sediment settling velocity, ωs (ms-1) in stagnant water is
dependent on the sediment diameter, d (m), sediment density, ρs
(kgm-3), water density, ρ (kgm-3),dynamic viscosity of water, μ
(kgm-1 s-1), and gravitational acceleration, g (ms-2).By applying
the dimensional analysis, develop the equation in terms of phi, π
to
explain the ωs.

How did Congress devise the Medicare D drug benefit? Would you
have designed it in that way? What would you have done differently
and why? Should physicians be allowed to purchase their own imaging
equipment? Why or why not?

A heating system is designed to keep the inner wall surface
temperature of a room at
25C. Only one wall of the room is contacted with the outer
environment. The crosssectional view of the wall is schematically
shown in Fig. H1. The height, width and
thickness of the wall are 2.5 m, 10 m and 0.2 m, respectively.
The wall is made from red
bricks with a thermal conductivity of 0.72 W/m.K and solar
absorptivity of s = 0.63.
