An ideal Rankine cycle with reheat uses water as the working fluid. The conditions at the inlet to the first-stage turbine are p1 5 2500 lbf/in.2, T1 5 10008F. The steam is reheated at constant pressure p between the turbine stages to 10008F. The condenser pressure is 1 lbf/in.2 (a) If p/p1 5 0.2, determine the cycle thermal efficiency and the steam quality at the exit of the second-stage turbine.

Explanation:

A) Determine the primary consolidation settlement

attached below is the detailed solution

primary consolidation = 358.77 mm

B) first calculate the degree of consolidation

looking at the attached graph at u = 46% , Tv = 0.35

using the formula ;  Tv = ( Cv*T ) / H^2

where ; Cv = 3.5m^2

             Tv = 0.35

             H = 3 m ( single drained )

hence T = ( Tv * H^2 ) / Cv

              = ( 0.35 * 9 ) / 3.5

              = 0.9 years ≈  1 year

attached below is the remaining part of the solution

Answer:

See explanation

Explanation:

a) The transformer must be a step down transformer because the secondary voltage which it supplies is less than the primary voltage.

b) From;

Ns/Np = Es/Ep

Where;

Ns= number of turns in secondary coil

Np= number of turns in primary coil

Es= voltage in secondary coil

Ep= voltage in primary coil

NsEp = EsNp

Ns = EsNp/Ep

Ns = 10 * 500/120

Ns = 42 turns

c) From;

Es/Ep = Ip/Is

EsIs = EpIp

Ip = EsIs/Ep

Ip = 10 * 900 * 10^-3/120

Ip = 75 mA

You get a result immediately from Euler's formula:

e ^(i π/2) = cos(π/2) + i sin(π/2) = 0 + i * 1 = i

Answer:

t₁ = 378.668 K

Explanation:

From the given information:

The heat dissipated (q) from the electrical device = [tex]10^4 W/m^2[/tex]

The contact resistance between device and aluminium;

(R_{const} ) = 0.5× 10⁻⁴ m² K/W

Conductivity of aluminum (k)  = 238 \ W/mK

The thickness of aluminum plate (L) = 0.004 m

Convection coefficient (h) = 100 \ W/m^2 K

Surrounding temperature (t_2) = 278 \ k

According to Fourier's law of heat conduction.

[tex]q = \dfrac { t_1- t_2 }{R_{const} + \dfrac{L}{k} + \dfrac{1}{h} }[/tex]

[tex]10^4 = \dfrac{t_1 - 278}{0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100} }[/tex]

[tex]10^4 *( 0.5 \times 10^{-4} + \dfrac{0.004}{238} + \dfrac{1}{100}) = t_1 - 278[/tex]

[tex]100.668 = t_1 -278[/tex]

t₁ = 378.668 K

Answer:

b. Transfer pipets; more accurate; measuring pipets.

Explanation:

Transfer pipets can be defined as an ungraduated or graduated disposable plastic instrument which are typically used in science laboratories to transfer or deliver liquids that are small in volume (microliters) . Also, they are generally being referred to as chemical

droppers, teat pipets, eye droppers, pasteur pipets, or droppers. It is made up of an ultra-clear long, slender tube with low density polyethylene (LDPE) and an integral molded bulb. The molded bulb allows a fixed volume of the desired liquid to be dispensed (transfered) or aspirated through compression and relaxation.

Hence, transfer pipets are calibrated to deliver one fixed volume and are more accurate than measuring pipets because of its long, slender tube which limits errors.

Transfer pipets are measurement pipets since they are calibrated to provide a specific volume.

Transfer pipets have been ungraduated as well as graded disposable plastic instruments that were already commonly used during research labs to transmit as well as distribute small-volume liquids.

Combining compression as well as relaxation, the molded bulb permits a set volume of such necessary fluid material to be administered as well as inhaled.

Thus the response above is correct.

Answer:

Since the farmer wants to buy a 10 kg bag of fertilizer, he should buy it from merchant A. However, Merchant A and B are selling at the same price for a unit value. In other words, Both Merchant A and B are selling 1kg of dry fertilizer for $1.

Explanation:

Which merchant has the better deal means which merchant offers the farmer a better deal.

For Merchant A,  10 kg bag = $10

meaning it contains a real 10 kg bag of dry fertilizer which the farmer can use without losing any Kg to drying.

While for Merchant B, 10 kg bag = $8

where the 10kg = 80% dry fertilizer + 20% water content

But the farmer can only use the solid constituents of the bag which means,

Merchant B is giving 80/100 x 10Kg of dry fertilizer for $8

That is, 8kg for $8

Since the farmer wants to buy a 10 kg bag of fertilizer, he should buy it from merchant A. However, Merchant A and B are selling at the same price for a unit value. In other words, Both Merchant A and B are selling 1kg of dry fertilizer for $1.

Follows are the solution to the given question:

Explanation:

In the environment of the piles of earth, its spacecraft faces extreme temperatures:

Therefore, to prevent satellite build sustainability, a temperature control system must be used.

Its skin must be rather permeable in physiological terms.

Its shuttle's surface should have adhered to both the material well.

Whether it gets broken, it ought to be easy to repair.

All tile mostly on the cutter is composed of silicon dioxide particles, that are bonded and create a tile of very low density.

Its heat transfer is so small that even a person may hold a burning hot side on one side of the tile.

Skin that uses a rubber resin to ensure that perhaps the powers may not release the cutting that heat-treated will then the internal body.

The design requirements that led to the combination of ceramic tiles and aluminium materials for the hull of shuttle space are; discussed below.

The space shuttle experiences extreme temperatures during re-entry into the earths atmosphere. Thus, as a result, a thermal protection system must be provided to help prevent damage of the shuttle structure.

Therefore, the skin must be made up of material that has an exceptionally low thermal conductivity and also the material must be able to be firmly attached to the skin and also be able to be easily repaired in case of any damage.

Secondly, the tiles used on the space shuttle will have to be composed of silica fibers that are bonded together to generate a ceramic of low density. The thermal conductivity of the ceramic would have to be low such that if you touch one end while the other is very hot, you will not feel the hotness.

Now, the tiles will be attached to the shuttle skin with the aid of a rubbery polymer which ensures that the forces don't break the tile loose which will then expose the underlying skin to high temperatures.
