Answer:
hello some data related to your question is missing attached below is the missing data
answer : 63700 Ib/hr
Explanation:
Given data :
Limestone mix : consists of 94% CaCO3 and 6% inert material
Actual feed rate = 36,000 Ib/hr
SO2 in flue gas = 20,314 Ib/hr
FGD efficiency = 97%
resulting sludge contains 58% solids
Calculate the Total sludge production rate
First : determine SO2 removed in sludge
= 0.97 * 20314
= 19704.58 Ib/hr
next : moles of SO2 removed
= 19704.58 / 64 Ib/ Ib mol
= 307.88 Ib mol / hr
also moles of CaSO3 produced = 307.88 Ib mol / hr
mass of CaSO3 = 307.88 * 120 = 36946.09 Ib/hr
Therefore Total sludge production rate
= 36946.09 / 0.58
= 63700.15 Ib/hr

Argue why electrode therapy is NOT the most effective treatment for brain disorders, and recommend an alternative treatment.
Answer:
Due to risk of damaging of brain.
Explanation:
The electrode therapy is not the most effective treatment for brain disorders because there are various other treatments which can treat the brain disorder without causing damage to the brain. electrode therapy greatly damaged the brain instead of treatment of brain disorder. Medication is the best way to treat brain disorder so that's why electrode therapy is not considered as the most effective treatment for brain disorders, and the doctors recommend an alternative treatment.
Railroad tracks made of 1025 steel are to be laid during the time of year when the temperature averages 4C (40F). Of a joint space of 5.4 mm (0.210 in.) is allowed between standard rails of length 11.9 m (39 ft), what is the highest possible temperature that can be tolerated without the introduction of thermal stresses
Answer:
41.5° C
Explanation:
Given data :
1025 steel
Temperature = 4°C
allowed joint space = 5.4 mm
length of rails = 11.9 m
Determine the highest possible temperature
coefficient of thermal expansion ( ∝ ) = 12.1 * 10^-6 /°C
Applying thermal strain ( Δl / l ) = ∝ * ΔT
( 5.4 * 10^-3 / 11.9 ) = 12.1 * 10^-6 * ( T2 - 4 )
∴ ( T2 - 4 ) = ( 5.4 * 10^-3 / 11.9 ) / 12.1 * 10^-6
hence : T2 = 41.5°C

Explanation:
Consider a homogeneous, bare, spherical, source-free, critical, uranium-fueled reactor operating at a power Po. Explain how and why the power increases, decreases, or remains unchanged as a result of each of the separate changes to the reactor.
a. The reactor is deformed into the shape of a football (ellipsoid).
b. A person stands next to the core.
c. The temperature of the core is raised.
d. A neutron source is brought close to the core.
e. An energetic electron beam impacts the core.
f. The reactor is run at high power for a long time.
g. The core is launched into outer space.
h. A sheet of cadmium is wrapped around the core.
i. The enrichment of the fuel is increased.
Answer:
a) unchanged
b) unchanged
c) Increase
d) Increase
e) unchanged
f ) Increase
g) unchanged
h) decrease
i) unchanged
Explanation:
Determine how and why the power increases, decreases, or remains unchanged
a) The reactor been deformed will not cause an increase in power i.e. power remains unchanged and this is because power change/generated does not depend on dimension
b) No change will happen to the power ( Unchanged )
c) When the temperature of the core is raised the power increases and this is because of the increase in bombarding of particles causing an increase in charge particle
d) When a neutron source is brought close to the core the power will increase and this is because the presence of more neutron in the core results to an increase in energy released ( more power will be generated )
e) An energetic electron beam impacting the core will not cause an increase in power ( reason been that it is lighter than neutron ) power unchanged
f ) When the reactor is run at a high power there would be an increase in power generated
g) When the core is launched into outer space the power generated remains unchanged
h) when a sheet of Cadmium is wrapped around the core the power generated will be decreased ( reason : Cadmium can absorb neutrons thereby reducing reaction)
i) Increase in the enrichment of the fuel will not cause an increase in the power generated but it will sustain the reaction ( unchanged power )
Leticia radio is getting interference whenever she uses it in her dining room. What's the most likely reason/s.
Answer: D. There is a dimmer switch
Explanation:
Dimmer switches have been known to cause radio interference especially the solid state ones. To counter this, dimmer switches usually come with a component to suppress radio interference, this doesn't work for all dimmers and the cheaper dimmers are usually more prone to this problem.
If Leticia's dining room makes use of a dimmer switch, it is the most probable reason for radio interference.
A key joint in a precision machining process has a lower specification limit of a width of 0.99 mm and an upper specification limit of 1.01 mm. The standard deviation is 0.005 mm and the mean is 1 mm. What is the process capability index for the precision machining process
Answer:
the process capability index for the precision machining process is 0.667
Explanation:
Given the data in the question;
Lower Specification Limits LSL = 0.99 mm
Upper Specification Limits USL = 1.01 mm.
The standard deviation σ = 0.005 mm
mean μ = 1 mm
capability index Cpk = ?
Cpk = min( USL - μ / 3σ, μ - LSL / 3σ )
we substitute
Cpk = min( 1.01 mm - 1 mm / 3(0.005 mm ), 1 - 0.99 mm / 3(0.005 mm) )
Cpk = min( 0.01 mm / 0.015 mm, 0.01 mm / 0.015 mm )
Cpk = min( 0.6666, 0.6666 )
∴ Cpk = 0.6666 ≈ 0.667
Therefore, the process capability index for the precision machining process is 0.667
Air entrainment is used in concrete to: __________.
1. Strengthen the concrete
2. Increase the resistance of the concrete to freeze thaw damage
3. Create a better surface appearance
4. Make the concrete easier to handle during placement
5. Help evaporate excess water from the curing concrete
The answer is number 2) Increase the resistance of the concrete to freeze-thaw damage.
Air entrainment is used in concrete to Increase the resistance of the concrete to freeze thaw damage.
What is air entrainment?Microscopic air bubbles embedded in the concrete's surface reduce internal pressure by creating little spaces for water to expand into during freeze-thaw cycles.
Without these pockets, water has nowhere to escape, which causes concrete to crack and/or scale, severely reducing the lifespan of a structure. An air entraining additive, or AEA, is used to add air to the concrete mix.
To fit the requirements of the task at hand, a mix's air content can be changed. When pouring concrete in locations that experience freeze-thaw conditions, using air-entrained concrete is advantageous.
Therefore, Air entrainment is used in concrete to Increase the resistance of the concrete to freeze thaw damage.

Answer:
Space Rovers
Explanation:
The engineering advancement of the invention space rovers has changed space exploration tremendously. The first space rover ever to go out onto another planet was made by NASA and put on mars to learn more about the red planet and see if there where any plausible signs of past or maybe even present life. This mission was incredibly successful and for the first time in space exploration history, there was a spacecraft that you could move around that could with do the conditions of the planet for weeks, months, sometimes years at a time, moving around taking pictures and constantly collecting data. This was revolutionary for scientists, this way they could get copious amounts of information just on rover and not having to send multiple crafts only to die in the first few hours but sending back a relative amount of information. With rovers you can have them collect samples and bring the back to earth, not something that could’ve been done without a human, until rovers. They have completely changed and improved collecting data from other planets and have been one of the most revolutionary inventions when it comes to space exploration.

Polarization: Unpolarized light passes through three ideal polarizing filters. The first filter is oriented with a horizontal transmission axis, the second one has its transmission axis at 30° from the horizontal, and the third filter has a vertical transmission axis. What percent of the light gets through this combination?
Answer:
the percentage of light that gets through this combination is 9.38
Explanation:
Given the data in the question;
Let us represent the incident unpolarized light with [tex]I_0[/tex].
So, the amount of light intensity passing through the first polarizer will be;
[tex]I_1[/tex] = [tex]I_0[/tex] / 2 ------ let this be equation 1
An the amount of light intensity passing through the second polarizer will be;
[tex]I_2[/tex] = [tex]I_1[/tex]cos²θ
given that; the second one has its transmission axis at 30°
so, we substitute;
[tex]I_2[/tex] = [tex]I_1[/tex] × cos²( 30° )
[tex]I_2[/tex] = [tex]I_1[/tex] × 0.75
[tex]I_2[/tex] = 0.75[tex]I_1[/tex]
from equation; [tex]I_1[/tex] = [tex]I_0[/tex] / 2
[tex]I_2[/tex] = 0.75( [tex]I_0[/tex] / 2 )
[tex]I_2[/tex] = 0.375[tex]I_0[/tex] .
Now, the amount of light intensity passing through the third polarizer will be;
[tex]I_3[/tex] = [tex]I_2[/tex]cos² ( 90° - 30° )
[tex]I_3[/tex] = [tex]I_2[/tex] × cos²( 60° )
[tex]I_3[/tex] = [tex]I_2[/tex] × 0.25
we substitute
[tex]I_3[/tex] = 0.375[tex]I_0[/tex] × 0.25
[tex]I_3[/tex] = 0.09375[tex]I_0[/tex]
∴ [tex]I_3[/tex]/[tex]I_0[/tex] × 100 = 0.09375 × 100
⇒ 9.38%
Therefore, the percentage of light that gets through this combination is 9.38

a poorly tighten terminal is often the cause of a/an ? a) open circuit b) circuit breaker interrupt c)short circuit d) ground fault
Answer: b) circuit breaker interrupt
Explanation:
Wires connect to outlets through terminals and these terminals need to be tight to ensure that electricity flows with the minimum amount of resistance.
If the terminal is poorly tightened, what happens is that resistance will build up as the appliance is being used and this resistance will make the terminal hotter.
The heat will continue to rise until the circuit breaker trips to interrupt the circuit and protect the appliance.
