With regard to the data rate, note that since the message is not that big, X is likely to be on the order of 1 millisecond. (Option C)

The speed of the cars   is irrelevant in this scenario.The only thing that matters isthe amount of time it takes to transmit the data.

The data rate of the wireless technology is   equivalent to fast Ethernet speed, which is 100 Mbps.The message is 19.9452909 MB, which is 19,945,290.9 bytes. The time it takes to transmitthe message   is

Answer:

  13/80

Explanation:

The product is ...

  (1 3/10)×(1/8) = (13/10)×(1/8) = (13×1)/(10×8) = 13/80

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

To calculate the required processing and assembly operations, workers, and total floor space for the new factory, we can break down the problem into smaller parts and analyze each element.

(a) Processing and assembly operations:

Number of components made in the factory: 250 components * 35% = 87.5 (round up to 88 components)

Processing operations for components: 88 components * 8 processing operations = 704 processing operations

Assembly operations for final product: 1 assembly operation (as each product is assembled in one workstation)

Total operations = 704 processing operations + 1 assembly operation = 705 operations

(b) Number of workers (direct labor only):

Processing workers: 704 processing operations / 1 (one worker per work cell) = 704 workers

Assembly workers: 13 models * 1000 units/model = 13,000 units/year

Assembly time per unit: 48 min/unit = 0.8 hr/unit

Assembly time for all products: 13,000 units * 0.8 hr/unit = 10,400 hr

Assembly workers required: 10,400 hr / 2,000 hr/shift = 5.2 (round up to 6 workers)

Total workers = 704 processing workers + 6 assembly workers = 710 workers

(c) Total floor space required:

Processing floor space: 704 work cells * 25 m2/cell = 17,600 m2

Assembly floor space: 6 workstations * 25 m2/station = 150 m2

Total production area: 17,600 m2 + 150 m2 = 17,750 m2

Additional allowance (45%): 17,750 m2 * 45% = 7,987.5 m2

Total floor space = 17,750 m2 + 7,987.5 m2 = 25,737.5 m2 (round to 25,738 m2)

In summary, the XYZ Company will require:

(a) 705 processing and assembly operations,

(b) 710 workers (direct labor only), and

(c) 25,738 m2 of total floor space for the new plant.

The injection molding department of a company that operates 24x7 uses an average of 34 gallons of special lubricant per day. The usage of lubricant is normally distributed with a standard deviation of 4.4 gallons per day and it takes 6.5 weeks for an order of lubricant to be delivered. If the largest service level is 73% The reorder point for the injection molding department is approximately 1549.508 gallons.

To calculate the reorder point, we need to consider the lead time demand, which is the demand during the time it takes for a new order to be delivered.

Given that the injection molding department operates 24x7 and uses an average of 34 gallons of special lubricant per day, we can calculate the daily demand as 34 gallons.

Since the demand follows a normal distribution with a standard deviation of 4.4 gallons per day, we can use the Z-score formula to calculate the safety stock. The Z-score represents the number of standard deviations from the mean.

To determine the Z-score corresponding to a service level of 73%, we can use a Z-table or a statistical calculator. The Z-score for a 73% service level is approximately 0.57.

Next, we need to calculate the lead time demand. The lead time is given as 6.5 weeks, and since there are 7 days in a week, the lead time is equal to 6.5 x 7 = 45.5 days.

To calculate the lead time demand, we multiply the average daily demand by the lead time in days. Therefore, the lead time demand is 34 gallons/day x 45.5 days = 1547 gallons.

To calculate the reorder point, we add the lead time demand to the safety stock. The safety stock is given by the formula: Safety Stock = Z-score x standard deviation.

Using the given standard deviation of 4.4 gallons per day and the calculated Z-score of 0.57, the safety stock is 0.57 x 4.4 gallons/day = 2.508 gallons.

Finally, we can calculate the reorder point by adding the lead time demand to the safety stock: Reorder Point = Lead time demand + Safety stock.

Reorder Point = 1547 gallons + 2.508 gallons = 1549.508 gallons.

Lens shades 4 to 6 are ideal for gas welding or oxyfuel torch welding/ oxyfuel gas cutting because In AWS Z49.1, the numbers for welding lens shades range from 4 to 14. Lens shades 4 to 8 are useful for low light intensity welding and cutting tasks such as gas cutting, brazing, or soldering, among others.

Selecting the right lens shade for welding:

The first and most important point to remember is to never look at welding without wearing black safety glasses or a suitable helmet. Next, what is the appropriate glass shade for various welding processes?

Looking directly at the welding arc without eye protection, or failing to follow this rule, can result in varying degrees of eye burn.

These burns do not usually result in permanent damage, but they can be excruciatingly painful for several days after exposure.

A helmet-style head shield, as shown in the figure below, is standard equipment for shielding the welder's face and eyes from the arc's direct rays.

To reduce reflection, these shields are typically made of a non-flammable insulating material and are black or gray in color. They are designed to shield the face, neck, and ears from the arc's direct radiant energy.

Glass lens shade for Gas welding and Gas cutting:

Lens shades 4 to 6 are ideal for gas welding or oxyfuel torch welding. The gas lens for oxyfuel gas cutting is determined by the material thickness to be cut, and the same is true for OFW welding, where the thickness to be welded determines the lens shade.

Answer:

Explanation:

Consider the outer surface of the roof to be \(T_{out}\)

Since, the heat conducted is equal to the sum of the heat transferred through convection and the rest by radiation

\(Q_{cond}=Q_{rad}+Q_{conv}\)

Rewrite the equation as follows

\(kA_s\frac{\Delta T}{L} =\epsilon \sigma A_s(T_s^4-T_{\infty}^4)+hA_s \Delta T\\\\k\frac{\Delta T}{L} =\epsilon \sigma (T_s^4-T_{\infty}^4)+h \Delta T\)

\(k\frac{T_{in}-T_{out}}{L} =\epsilon \sigma (T_{out}^4-T_{rad}^4)+h(T_{out}-T_{\infty})\)

subsititute

k = 2 W/m

\(15^o C=T_{in}\)

0.22 for L

\(0.9 = \epsilon\)

\(5.67\times 10^{-8}W/m^2.K^4=\sigma\)

\(255=T_{rad}\)

\(15W/m^2.K = h\)

\(10^oC=T_{\infty}\)

\(2\times \frac{15 -T_{out}}{0.22} =[0.9\times(5.67\times10^-^8)\times((T_{out}+273)^4-255^4)]+[15\times(T_{out}-10)]\\\\T_{out}=7.7^oC\)

Hence, the temperature of outer surface of the roof is \(T_{out}=7.7^oC\)

Calculate the surface area of the roof

\(A_s=b\times l\)

Here, b is the width , l is the length

substitute 15 for b , 20 for l

\(A_s=15 \times 20\\\\=300m^2\)

Write the equation for conduction

\(Q_{cond}=kA_s\frac{\Delta T}{L}\)

substitute 2W/m.K for k

\(300m^2 \ \ for \ A_s\\\\(15-7.7)^oC \ \ for \ \Delta T\\\\0.22m \ for \ L\)

\(Q_{cond}=2\times 300 \times \frac{15-7.7}{0.22}\\\\=19,000\)

Therefore, the total heat transferred through conduction is \(Q_{cond}=19,9009W\)

Consider the amount of  natural gas required be R and the cost incurred in running  the furnace through the night be M

\(R=\frac{Q_{cond}}{0.85} \times T\)

Duration of time T = 14 x 3600s

\(R=\frac{19909\times(14\times3600)}{0.85}kJ\\\\= \frac{19909\times(14\times3600)}{0.85\times105500}therm\\\\=11.2 \ therm\)

And the required money for the gas M = 11.2 x $1.2

= $13.44

Therefore, the money lost through the roof due to the heat transfer M=$13.44

The largest potential fuel resource that is estimated to exist is natural gas.

Natural gas is a fossil fuel that is found underground and is composed primarily of methane. It is believed that there are vast reserves of natural gas around the world, with some estimates suggesting that there is enough natural gas to meet global demand for hundreds of years. Natural gas is considered to be a cleaner-burning fuel than other fossil fuels such as coal or oil, and is therefore often touted as a more environmentally-friendly energy source. In recent years, there has been a significant increase in the use of natural gas for power generation and other applications, as countries seek to transition away from more polluting fossil fuels.
