Answer:

The distributions of solid wastes produced daily at a commercial facility are normally distributed with a mean of 10 yd3 and a standard deviation of 7 yd3. If you were to make a container size recommendation for this facility, what size would you propose? What important tradeoffs should be considered when selecting the size of the container?

It's quite perplexing to determine the perfect size of container for a facility whose waste quantity varies and is subject to changes frequently. A certain degree of burstiness is present in the distribution of solid waste generated on a daily basis in a commercial facility. However, using the available mean and standard deviation values, we can infer that a container size of 24 yd3 should be sufficient to hold the daily waste generated, considering that it's two standard deviations above the mean.

When selecting a container size, various tradeoffs must be considered. A large container is more efficient, as it would not require to be emptied as frequently, but it might be expensive and may take up more space. A smaller container may be less expensive and take up less space, but it would need to be emptied more frequently, which can result in higher transportation costs and more time spent on waste management. It is therefore essential to strike a balance between the frequency of emptying and the container size to ensure that the waste is managed effectively and efficiently.

The MMC of the hole diameter is 10.10 mm. The least material condition (LMC) is the smallest size limit of a part that is acceptable for use.  LMC is the smallest allowable size limit that will still allow the part to function as intended. In this case, we will calculate the LMC for a part with a length of \(35.00 ± 0.15 mm.\)

To calculate the LMC, we must subtract the tolerance from the nominal value. The nominal value is the target value of the part dimension. In this case, the nominal value is 35.00 mm.

LMC = Nominal Value - Tolerance LMC = \(35.00 - 0.15LMC = 34.85 mm\)

Therefore, the LMC for the given part is 34.85 mm.

The Maximum Material Condition (MMC) is the largest size limit of a part that is acceptable for use. In other words, MMC is the largest allowable size limit that will still allow the part to function as intended. In this case, we will calculate the MMC of the hole diameter with dimension \(10.0 ± 0.10 mm\).

To calculate the MMC, we must add the tolerance to the nominal value. The nominal value is the target value of the part dimension. In this case, the nominal value is 10.0 mm.

MMC = Nominal Value + Tolerance MMC = \(10.0 + 0.10MMC = 10.10 mm.\)

At time t=2 min, the concentration inside the tank is 0.042 kg/kg and the concentration outside the tank is 0.476 kg/kg.

To determine the concentration inside and outside the tank at 2 minutes, we need to use the mass balance equation:

mass in - mass out + mass generated = change in mass in the tank

At time t=0, the mass in the tank is 8 kg, and there is no mass generated. Thus, we have:

(2.2 + 0.2) kg/min - 2 kg/min + 0 kg/min = dM/dt

Simplifying, we get:

dM/dt = 0.4 kg/min

Integrating both sides, we get:

M(t) = M(0) + (dM/dt) * t

Plugging in the values, we get:

M(2) = 8 kg + (0.4 kg/min) * 2 min = 9.6 kg

Now, we can calculate the concentration inside and outside the tank:

Concentration inside the tank:

At time t=0, the concentration inside the tank is:

Cin(0) = 0 kg/kg (since there is no salt in the tank initially)

At time t=2 min, the amount of salt in the tank is:

Min(2) = 0.2 kg/min * 2 min = 0.4 kg

Thus, the concentration inside the tank is:

Cin(2) = Min(2) / M(2) = 0.4 kg / 9.6 kg = 0.042 kg/kg

Concentration outside the tank:

The rate of salt leaving the tank is 2 kg/min, and at time t=2 min, the total amount of salt leaving the tank is:

Mout(2) = 2 kg/min * 2 min = 4 kg

Thus, the amount of salt remaining in the tank is:

Mrem(2) = M(0) + Min(2) - Mout(2) = 8 kg + 0.4 kg - 4 kg = 4.4 kg

The total mass leaving the tank is 2 kg/min * 2 min = 4 kg. Thus, the concentration outside the tank is:

Cout(2) = Mout(2) / (M(0) + Min(2)) = 4 kg / 8.4 kg = 0.476 kg/kg

Therefore, at time t=2 min, the concentration inside the tank is 0.042 kg/kg and the concentration outside the tank is 0.476 kg/kg.

Efficiency is defined as any performance that uses the fewest number of inputs to produce the greatest number of outputs. Simply put, you're efficient if you get more out of less.

Explanation:

Mechanical advantage is a measure of the force amplification achieved by using a simple machine, such as a wheel and axle. The faucet, which is an example of a wheel and axle, has a mechanical advantage of 10.

In this problem, we are given the radii of the faucet wheel and axle and are asked to calculate the mechanical advantage.

The mechanical advantage (MA) of a wheel and axle is calculated using the following formula:

MA = Radius of wheel / Radius of axle

In this problem, the radius of the faucet wheel is 5 cm, and the radius of the axle is 0.5 cm. We can now plug these values into the formula:

MA = 5 cm / 0.5 cm

The mechanical advantage of this simple machine (faucet as a wheel and axle) is 10. This means that the input force applied to the faucet wheel is amplified by a factor of 10 when transferred to the axle.

Answer:

the projected volumetric flow rate of fuel for each of the two Dreamliner engines is 0.005 m³/s

Explanation:

Given the data in the question;

First we determine the fuel economy of Boeing 767

Range = 12,000 km

fuel capacity = 90,000 L

so,  fuel economy of Boeing 767 will be

η\(_f\) = Range / fuel capacity

η\(_f\) = ( 12,000 km / 90000 L ) ( 1000m / 1 km) ( 3.7854 L/gal × 264.2 gal/m² )

η\(_f\)  = 133,347.024 m/m³

Now, Boeing 787 is 20% more fuel efficient than Boeing 767

so fuel economy of Boeing 787 will be;

⇒ (1 - 20%) × fuel economy of Boeing 767

⇒ (1 - 0.2) × 133,347.024 m/m³

⇒ 0.8 × 133,347.024 m/m³

⇒ 106,677.6 m/m³

Hence, fuel economy of Boeing 787 dream line engine is

⇒ 106,677.6 m/m³ / 2 = 53,338.8 m/m³

Next, we find the velocity of Boeing 787

\(V_{787\) = Mach number of 787 × speed of sound

given that; Mach number is 0.85 and speed of sound is 700 mph

we substitute

\(V_{787\) = (0.85 × 700 mph) × ( 1 hr / 3600 s ) × ( 1609 m / 1 mile )

\(V_{787\) = 265.9319 m/s

Now, to get the Volume flow rate for each dream liner engine { Boeing 787 };

Volumetric flow rate = velocity of flight / fuel economy

we substitute

= 265.9319 m/s / 53,338.8 m/m³

= 0.0049857 ≈ 0.005 m³/s

Therefore,  the projected volumetric flow rate of fuel for each of the two Dreamliner engines is 0.005 m³/s

To meet the necessary criteria for effective fall restraint,the principles are Adequate Anchorage,Proper Fit and Adjustment,Maximum Arrest Force,Compatibility and Integrity and Proper Training and Use.

Fall restraint systems are designed to prevent a person from falling while working at heights. To meet the necessary criteria for effective fall restraint, the system must adhere to several key principles:

1. Adequate Anchorage: The system should be securely anchored to a structure capable of withstanding the anticipated loads. Anchorage points must be structurally sound and capable of supporting the maximum forces that may be exerted during a fall.

2. Proper Fit and Adjustment: The fall restraint system should be properly fitted and adjusted to the individual worker. This includes ensuring that harnesses, belts, and lanyards are correctly sized and adjusted for the user's body type and work requirements.

3. Maximum Arrest Force: The fall restraint system should limit the maximum force exerted on the worker's body in the event of a fall. This helps minimize the risk of injury by reducing the impact force transmitted to the body during a fall arrest.

4. Compatibility and Integrity: All components of the fall restraint system must be compatible with each other and function together as intended. This includes the harness, lanyard, connectors, and anchorages.

Regular inspections and maintenance should be conducted to ensure the integrity of the system.

5. Proper Training and Use: Workers must be adequately trained in the proper use of the fall restraint system. They should understand how to properly don and doff the equipment, inspect it for defects, and recognize when the system is not suitable for use.

By meeting these criteria, fall restraint systems can effectively protect workers at heights, reducing the risk of falls and their associated injuries.

The distributed load, in kips/ft, on a beam supporting an 8" thick stone reinforced concrete slab with a tributary width of 10 feet is 1.2 kips/ft.

A distributed load is a load applied along a line over a given area or length. It is commonly expressed as a force per unit length or area, and its application is consistent along the length of the beam. The beam's weight is a type of distributed load since it is applied uniformly over the beam's length.

The distributed load on the beam is the weight of the slab divided by its tributary area. The slab's tributary area is the area over which the slab is supported by the beam. The slab's tributary area is calculated by multiplying the tributary width by the slab's thickness.

In this case, the tributary width is 10 feet, and the slab thickness is 8 inches or 0.67 feet. The tributary area of the slab is, therefore, 6.7 square feet. The weight of the slab is determined by multiplying the slab's volume by its density. The density of reinforced concrete with stone aggregate is approximately 150 pounds per cubic foot. The slab's volume is determined by multiplying its tributary area by its thickness.

slab's weight = 6.7 * 0.67 * 150 = 674.25 pounds or 0.337125 kips

The distributed load =  slab's weight / tributary area = 0.337125 kips ÷ 6.7 ft² = 0.05 kips/ft

Therefore, the distributed load, in kips/ft, on a beam supporting an 8" thick stone reinforced concrete slab with a tributary width of 10 feet is 1.2 kips/ft.

     An op amp-based circuit known as a differentiator produces an output signal that is proportional to the differentiation of the input signal. In essence, an op amp differentiator is an inverting amplifier with an appropriate capacitor at its input end.

        Depending on the circuit time constant and the amplifier's bandwidth, the differentiator circuit produces the derivative of the input signal over a range of frequencies. Applying the input signal to the inverting input causes the output to be polarity-inverted with respect to the input signal.

       Why is a differentiator opamp used? The major application of this op-amp is to boost weak signal levels. Depending on the components used in the design, an op-amp differentiator can be either active or passive. We will utilize this differentiator amplifier in frequency modulators and wave shaping circuits because it essentially functions as a high pass filter.

      Why do op-amps utilize capacitors? A feedback capacitor is used in a typical op-amp circuit to restrict bandwidth. A feedback capacitor is a typical approach to minimize noise because restricting op-amp bandwidth will do so. Consider that a capacitor functions as a short to "high frequency" AC impulses in order to comprehend how the feedback capacitor operates.
