At a certain elevation, the pilot of a balloon has a mass of 120 lb and a weight of 119 lbf. What is the local acceleration of g

ravity, in ft/s2, at that elevation? If the balloon drifts to another elevation where g = 32.05 ft/s2, what is her weight, in lbf, and mass, in lb?

Response:

1) g=31.87ft/s^2

2)m=120

W=119.64lbf

Clarification:

initial segment

the weight of an object with a specified mass is determined using the equation

W=mg

we need to convert 120lb into slug

m=120lbx1slug/32.147lb=3.733slug

calculating for g

g=W/m

g=119/3.733=31.87ft/s^2

subsequent segment

the mass remains unchanged

m=120lb=3.733slug

Weight

W=3.733slug*32.05ft/s^2=119.64lbf

Describe the grain structure of a metal ingot that was produced by slow-cooling the metal in a stationary open mold.
pantera1 [220]
In the scenario of a metal ingot cooling slowly, the microstructure tends to be coarse. The surface, exposed to higher temperatures for extended periods during cooling, features smaller grain sizes as they have less time to form. However, as we delve deeper into the ingot, the grains gradually extend, leading to equiaxed grain formation at the center.

Viktor [230]

Explanation:

At a temperature of 33^{\circ} C and relative humidity of 86%, the humidity ratio stands at 0.0223 with a specific volume of 14.289.

At a temperature of 33^{\circ} C and relative humidity of 40%, the humidity ratio is 0.0066 while the specific volume is 13.535.

To determine the mass of air, the following formula can be used:

\begin{aligned}m _{1} &=\frac{ v }{ v }(1- w ) \\&=\frac{1 \times 10^{5}}{13.535}(1-0.0066) \\&=7339.49 lb / min \\v _{ a } &=\frac{ m _{1} v }{(1- w )} \\v _{ a } &=\frac{7339.49 \times 14.289}{(1-0.0223)} \\v _{ a } &=107266.0 ft ^{3} / min\end{aligned}

Now, we will calculate the volume

\begin{aligned}m _{ w } &=\frac{ v _{ a }}{ v _{ a }} w _{ a }-\frac{ v _{ i }}{ v _{ i }} w _{ i } \\&=\frac{107266.0}{14.289} \times 0.0223-\frac{100000}{13.535} \times 0.0066 \\&=118.64 lb / min\end{aligned}

The duration required to fill the cistern can be determined with the equation:

Time \(=\frac{\text { cistern volume }}{\text { removal water perminute volume }}\)

By substituting the values into the preceding formula, we find:

\(\frac{\left(15 \times 10^{3} L\right) \times\left(0.0353147 ft ^{3} / L \right)}{(118.641 b / min ) \times\left(\frac{1}{62.41 lb / ft ^{3}}\right)}\)\\\(=279.09\) minutes\\\(=4.65\) hours.

Thus, the hours necessary to fill the cistern amount to 4.65 hours.

The components of an electronic system dissipating 90 W are located in a 1-m-long circular horizontal duct of 15-cm diameter. Th
iogann1982 [279]

Answer:

Provided information

 an electronic system dissipating = 90 W

diameter = 15 cm

The duct has components cooled by forced air entering at 32°C with a flow rate of 0.65 m3 /min

85% of the generated heat is transferred to the air in the duct, and 15% is lost through the duct's outer surfaces.

See the attached images for the solution.

Explanation:

Consult the attached pictures for a thorough breakdown of the explanation.

___________ is NOT a common injury that an automotive tech may experience at work.
Viktor [230]

Answer: The most frequently occurring injuries were sprains/strains, accounting for 39% of the total; lacerations comprised 22%, and contusions represented 15%. Almost half (49%) of the injuries led to one or more days of lost or restricted work; 25% resulted in 7 or more days lost or restricted.

Explanation:

Sprains/strains were the predominant injuries happening, making up 39% of all cases, while lacerations followed at 22% and contusions at 15%. Of these injuries, 49% caused employees to miss or face restricted workdays, with 25% leading to a minimum of 7 days lost or restricted.
