6 0

Answer:

Pipe racks are construction in chemical and other industries plants, that support the pipe line, electric cables and instrument cable.

Explanation:

The pipe racks also used to support mechanical equipment as valve and vessels. You can transfer material between equipment and sorage or utility areas. Pipe racks aren´t only non-building constructions that have similiraties to the Steel buildings but also have additional loads style. The requirements found in the building codes apply and dictate some of the design requirements.

Some industry references exist to help the designer apply the intent of the code and follow expected engineering practices.

Pipe racks have design criteria: In most of the United States, the governing building code is the International Building Code.

Includes:

*Dead Loads

*Live Loads

*Thermal Loads

*Earthquake Loads

*Wind Loads

*Rain Loads

*Snow Loads

*Ice Loads

*Load Combinations

Also have Design Considerations:

*Layout

*Seismic

*Seismic System Selection

*Period Calculations

*Analisys Procedure

*Selection

*Equivalent Lateral Force Method Analysis

*Modal Response Spectra Analysis

*Drift

*Seismic Detailing Requirements

*Wind

*Pressures and Forces

*Coatings

*Fire Protection

*Torsion on Support Beams

What’s the density if the mass is 40.8g and the volume is 60mL?
luda_lava [24]

Answer:

We have the final answer as

<h2>0.68 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 40.8 g

volume = 60 mL

The density is

density =  \frac{40.8}{60}  \\

We have the final answer as

<h3>0.68 g/mL</h3>

Hope this helps you

Why are iron needles used in compasses
ludmilkaskok [199]

A compass needle points north because the north pole of the magnet inside it is attracted to the south pole of Earth's built-in magnet . <u><em>And irons are heavily attracked to magnet</em></u> .So this is why iron needles used in compasses .

In a titration of monoprotic acids and bases, there is a large change in pHA. at the point where pH = pKa of the acid.B. when th
Jobisdone [24]

Answer:

D. when the number of moles of acid is exactly equal to the number of moles of base.

Explanation:

<em>Regarding options A. and E</em>., pKa and pKb would only be taken into consideration if the titrations were of <em>weak</em> acids and bases. However it is possible to have a titration of monoprotic acids and bases with strong acids and bases.

Another way of looking at the answer is identifying <em>which one best describes the equivalence point</em>.

Why should the boiling point of the solvent be lower than the melting point of the compound being recrystallized?
exis [7]
The recrystallization solvent ought to have a genuinely low breaking point since it makes it simpler for the solvent to vanish out when the arrangement air drys.The breaking point ought to be bring down the softening purpose of the compound.If the breaking point is bigger than the dissolving purpose of the intensify, the crystals will liquefy and turn out as an oil rather than crystals. This would be difficult to examine.

Describe the orbital diagram of an atom with six electrons. Explain how this orbital diagram demonstrates Hund's rule.
densk [106]

Answer:

See explanation

Explanation:

According to Hund's rule, electrons must occur singly first before pairing takes place.

If I want to fill six electrons into orbitals, the filling of electrons will be as follows;

1s2 2s2 2p2.

The first four electrons are filled into the 1s and 2s levels having only one orbital each. The fifth and sixth electrons are filled into 2p orbitals. The 2p level have three degenerate orbitals. The two electrons are singly filled into each of the degenerate orbitals in accordance to Hund's rule.
