Anode beds are usually filled with coke breeze, which is a byproduct of coal. Coke breeze is a substance that is used as a bed material in many electrochemical processes. This substance is made up of fine particles of coke, which are produced during the process of manufacturing coke from coal.
Coke breeze is used as a bed material in anode beds because it has several properties that make it ideal for this purpose.
Firstly, coke breeze is a good electrical conductor, which means that it can carry the electrical current that is needed for the electrochemical process. Secondly, it has a high porosity, which allows for good gas flow and distribution. Finally, it is chemically stable, which means that it will not react with the substances that are being processed in the anode bed.
In conclusion, anode beds are usually filled with coke breeze, which is a substance that has several properties that make it ideal for use as a bed material. Its good electrical conductivity, high porosity, and chemical stability make it the perfect substance for carrying out electrochemical processes.

For a building to maintain positive pressure with various fuel-burning appliances operating, a(n) _____ should be used.
Answer:
A fan/blower should be used
Explanation:
In a building the air pressure could be positive or negative and each if these depends on the air tightness of the building and could also be caused sometimes by wind and other factors.
When there is positive pressure, we have it that the pressure in the building is more than the outside pressure. Positive pressure also helps with an improvement in the quality of air in a building since it would take out smokes and other particulates.
Therefore to maintain positive pressure a fan or blower should be used.

for a 10-ton-capacity refrigeration system, the pressure of refrigerant in the evaporator is 210 kpa, whereas in the condenser it is 750 kpa. if ammonia (r-717) is used under saturated conditions, calculate the theoretical power required to operate the compressor.
To calculate the theoretical power required to operate the compressor in a 10-ton-capacity refrigeration system using ammonia (r-717) under saturated conditions, we can use the following formula:Power = mass flow rate x specific enthalpy changeFirst, we need to determine the mass flow rate of the refrigerant. We can do this using the following formula:
Mass flow rate = refrigeration capacity / (specific enthalpy change x refrigerant density)
Since the refrigeration capacity is given as 10 tons, we need to convert this to kilowatts (kW) by multiplying by 3.517:
Refrigeration capacity = 10 tons x 3.517 kW/ton = 35.17 kW
Next, we need to determine the specific enthalpy change of the refrigerant. This can be found by subtracting the specific enthalpy of the refrigerant in the evaporator from the specific enthalpy of the refrigerant in the cSpecific enthalpy change = h2 - h1
To find the specific enthalpies, we can use a refrigerant table. For ammonia (r-717) at 210 kPa, the specific enthalpy in the evaporator (h1) is 349.7 kJ/kg, and at 750 kPa, the specific enthalpy in the condenser (h2) is 400.8 kJ/kg.Substituting these values into the formula, we get:Specific enthalpy change = 400.8 - 349.7 = 51.1 kJ/kg
Finally, we need to determine the refrigerant density. At 210 kPa, the density of ammonia (r-717) under saturated conditions is 480 kg/m³.Substituting all of these values into the mass flow rate formula, we get:
Mass flow rate = 35.17 kW / (51.1 kJ/kg x 480 kg/m³) = 1.007 kg/s
Now we can use the power formula to calculate the theoretical power required to operate the compressor:Power = 1.007 kg/s x 51.1 kJ/kg = 51.48 kWTherefore, the theoretical power required to operate the compressor in a 10-ton-capacity refrigeration system using ammonia (r-717) under saturated conditions is approximately 51.48 kW.

Answer:
Use a non digital multimeter.
Explanation:
If a digital multimeter displays "000" when reading amperage, the technician should adjust the multimeter to a higher amperage range.
Why should the technician do this?This is because "000" typically indicates that the current being measured is too low for the current range selected on the multimeter.
By switching to a higher amperage range, the technician can get a more accurate reading and ensure that the multimeter is properly measuring the current in the circuit under test.

A coil having a resistance of 10 ohms and an inductance of 4 H is switched across a 20W dc source. Calculate (a) time required by the current to reach 50% of its final steady value, (b) value of the current after 0. 5 second
(a) The time constant of the circuit can be calculated as:
τ = L/R = 4/10 = 0.4 seconds
At t = τln(2), the current will have reached 50% of its final steady value. Therefore:
t = τln(2) = 0.4ln(2) ≈ 0.277 seconds
(b) The current in the circuit can be calculated using the formula:
i(t) = (V/R)(1 - e^(-t/τ))
At t = 0.5 seconds, we have:
i(0.5) = (20/10)(1 - e^(-0.5/0.4))
≈ 1.98 amps
Therefore, the value of the current after 0.5 seconds is approximately 1.98 amps.

A baker deck decorates 42 cupcakes and 30 minute she decorated cupcakes at a constant rate how many cups cage the baker decorate pre-minute
Answer: 1.4 cupcakes per minute.
Explanation:
Here's the correct question:
A baker decorates 42 cupcakes in 30 minutes. How many cupcakes can the baker decorate per minute?
Since the baker decorates 42 cupcakes in 30 minutes, the number of cupcakes that the baker decorates for each minutes since it's at a constant rate will be the total number of cupcakes made divided by the number of minutes. This will be:
= 42cupcakes / 30minutes
= 1.4 cupcakes per minute.
Therefore, the number of cupcakes that the baker can decorate per minute is 1.4cupcakes/minute
Consider the beam and loading shown where P is 144 kN and E = 200 × 109 Pa.
Determine the deflection at point C. (Round the final answer to two decimal places.)
The deflection at point C is 0.0025 m or 2.50 mm (rounded to two decimal places). To determine the deflection at point C, we can use the formula.
δ = (PL³)/(48EI)
Where δ is the deflection, P is the load, L is the length of the beam, E is the modulus of elasticity, and I is the moment of inertia.
First, we need to calculate the moment of inertia of the beam. Since it is a rectangular beam, the moment of inertia can be found using the formula:
I = (bh³)/12
Where b is the width and h is the height of the beam. In this case, b = 0.1 m and h = 0.2 m. So, I = (0.1 × 0.2³)/12 = 0.000133 m⁴.
Next, we can plug in the values to get:
δ = (144 × 10³ × 3³)/(48 × 200 × 10⁹ × 0.000133) = 0.0025 m

The settlement analysis for a proposed structure indicates that the underlying clay layer will settle 7.5 cm in 3 years, and that ultimately the total settlement will be about 32 cm. However, this analysis is based on the clay layer being doubly drained. It is suspected that there may be no drainage at the bottom of the layer (i.e., clay has single drainage condition). Answer the following questions based on single drainage only, assuming cv = 1.5 x 10-4 cm 2 /s for both single and double drainage.
a. How will the total settlement change from the double to the single drainage case?
b. How long will it take for 7.5 cm of settlement to occur if there is only single
Answer:
A) For a double drainage system the time taken for total settlement will differ from that of a single drainage system, because in a double drainage case clay water escapes from both sides unlike in a single drainage case. hence water and air will be be expulsed faster for a double drainage making it attain total settlement faster.
B) for only single = 12 years
Explanation:
Given data :
ultimate clay settlement = 32 cm
settlement of clay in 3 years = 7.5 cm
Cv ( coefficient of consolidation ) = 1.5 x 10^-4 cm^2 /s
A) For a double drainage system the time taken for total settlement will differ from that of a single drainage system, because in a double drainage case clay water escapes from both sides unlike in a single drainage case. hence water and air will be be expulsed faster for a double drainage making it attain total settlement faster.
note : Total settlement is the same in both drainage system.
B) Determine how long it will take for 7.5 cm of settlement to occur if there is only single
applying the relation below
Tv = Cv t / H^2
where Tv = time factor , d = thickness of layer , H = drainage path
Given that Tv and Cv are constant in both cases
t ∝ H^2 hence
\(\frac{t1}{t2} = \frac{H^21}{H^22}\) ------ ( 1 )
t1 = time for single drainage for d meters , t2 = time for double drainage for d meters
equation 1 can be rewritten as
t1/t2 = d^2 / (d/2)^2
∴ t1 = 4t2
given that t2 = 3 years ( value gotten from question )
t1 = 4 * 3 = 12 years
