Answer:

74,4 litros

Explanation:

Dado que

W = nRT ln (Vf / Vi)

W = 3000J

R = 8,314 JK-1mol-1

T = 58 + 273 = 331 K

Vf = desconocido

Vi = 25 L

W / nRT = ln (Vf / Vi)

W / nRT = 2.303 log (Vf / Vi)

W / nRT * 1 / 2.303 = log (Vf / Vi)

Vf / Vi = Antilog (W / nRT * 1 / 2.303)

Vf = Antilog (W / nRT * 1 / 2.303) * Vi

Vf = Antilog (3000/1 * 8,314 * 331 * 1 / 2,303) * 25

Vf = 74,4 litros

Answer:

u(y)/U = [(y/H) - ((H²/2μ)(dp/dx)(y/H))] × [(1 - y/H)]

Explanation:

The flow is steady, compressible and planar. Thus the incompressible the continuity equation is given as;

(δu/δx) + (δv/δy) = 0

The velocity(v) in the vertical direction would be zero at both boundaries as well as everywhere in the flow.

This means the continuity equation will dictate that:

∂u

/∂x = 0

It means that u is only just a function of y i.e. u = u(y).

Thus, The Navier-Stokes equation in the y-direction will now be reduced to:

∂p

/∂y = 0

This means the pressure can only then be a function of x.

The Navier-Stokes equation in the x-direction would be;

ρ[(∂u

/∂t) + u(∂u/∂x) + v(∂u/∂y) + w(∂u/∂z)] = -dp/dx + μ(∂²u/∂x²) + v(∂²u/∂y²) + w(∂²u/∂z²)

Recall that v = 0 and u = u(y).

Thus, the Navier-Stokes equation in the x-direction would now become;

∂²u/∂y² = (1/μ)(dp/dx)

We now Integrate twice with respect to y to give;

u(y) = (1/2μ)(dp/dx)y² + c1•y + c2)

At boundary condition of y = 0, C2 will be zero.

Thus;

u(y) = (1/2μ)(dp/dx)y² + c1•y)

At height of y = H, we have;

U = (1/2μ)(dp/dx)H² + c1•H) - - - (eq 1)

Making C1 the subject gives;

c1 = (U/H) - (H/2μ)(dp/dx)

Putting that for c1 in (eq 1) and rearranging to simplify gives us;

u(y)/U = [(y/H) - ((H²/2μ)(dp/dx)(y/H))] × [(1 - y/H)]

Answer:

the reduction in the heat gain is 2.8358 kW

Given that;

Shaft outpower of a motor  = 75 hp = ( 75 × 746 ) = 55950 W

Efficiency of motor  = 91.0% = 0.91

High Efficiency of the motor  = 95.4% = 0.954

now, we know that, efficiency of motor is defined as;  =  /

where   is the electric input given to the motor

so

=  /

we substitute

= 55950 W / 0.91

= 61483.5 W

= 61.4835 kW

now, the electric input given to the motor due to increased efficiency will be;

=  /

we substitute

= 55950 W / 0.954

= 58647.79 W

= 58.6477 kW

so the reduction of the heat gain of the room due to higher efficiency will be;

Q =  -

we substitute

Q = 61.4835 kW - 58.6477 kW

Q = 2.8358 kW

Therefore, the reduction in the heat gain is 2.8358 kW

(a) The probability of drawing a black fuse from the second toolbox is 4/7.

(b) The probability of drawing a white fuse from the second toolbox is 3/7.

(c) The probability that one fuse is white is 27/49.

To calculate the probabilities, we need to consider the number of white and black fuses in each toolbox.

First, let's determine the total number of fuses in each toolbox:

First Toolbox:

Total fuses = 4 white fuses + 3 black fuses = 7 fuses

Second Toolbox:

Total fuses = 3 white fuses + 5 black fuses = 8 fuses

(a) The probability that the fuse drawn from the second toolbox is black:

The probability of drawing a black fuse from the second toolbox depends on the fuse selected from the first toolbox. There are two scenarios to consider:

Scenario 1: The fuse selected from the first toolbox is black.

In this case, the second toolbox will have 3 black fuses remaining out of the total 7 fuses.

Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)

Probability = 3/7

Scenario 2: The fuse selected from the first toolbox is white.

In this case, the second toolbox will have 5 black fuses out of the total 7 fuses.

Probability = (Number of black fuses in the second toolbox)/(Total number of fuses in the second toolbox)

Probability = 5/7

To calculate the overall probability, we need to consider the probability of each scenario and weigh it by the probability of selecting a fuse of that color from the first toolbox. Since the fuse from the first toolbox has an equal chance of being white or black, we need to take an average of the probabilities in both scenarios.

Probability of drawing a black fuse from the second toolbox = (Probability of scenario 1 + Probability of scenario 2)/2

Probability of drawing a black fuse from the second toolbox = (3/7 + 5/7)/2

Probability of drawing a black fuse from the second toolbox = 8/14

Probability of drawing a black fuse from the second toolbox = 4/7

Therefore, the probability of drawing a black fuse from the second toolbox is 4/7.

(b) The probability that the fuse drawn from the second toolbox is white:

Similarly, we can calculate the probability of drawing a white fuse from the second toolbox. It will be the complement of the probability of drawing a black fuse.

Probability of drawing a white fuse from the second toolbox = 1 - Probability of drawing a black fuse from the second toolbox

Probability of drawing a white fuse from the second toolbox = 1 - 4/7

Probability of drawing a white fuse from the second toolbox = 3/7

Therefore, the probability of drawing a white fuse from the second toolbox is 3/7.

(c) The probability that one is white:

To calculate the probability that one fuse is white, we need to consider both scenarios: either the fuse drawn from the first toolbox is white and the fuse drawn from the second toolbox is black, or the fuse drawn from the first toolbox is black and the fuse drawn from the second toolbox is white.

Scenario 1: Fuse drawn from the first toolbox is white, and the second toolbox has a black fuse:

Probability = (Probability of drawing a white fuse from the first toolbox) * (Probability of drawing a black fuse from the second toolbox)

Probability = (3/7) * (5/7)

Scenario 2: Fuse drawn from the first toolbox is black, and the second toolbox has a white fuse:

Probability = (Probability of drawing a black fuse from the first toolbox) * (Probability of drawing a white fuse from the second toolbox)

Probability = (4/7) * (3/7)

To calculate the overall probability, we need to sum up the probabilities of both scenarios:

Probability that one fuse is white = Probability

of scenario 1 + Probability of scenario 2

Probability that one fuse is white = (3/7) * (5/7) + (4/7) * (3/7)

Probability that one fuse is white = 15/49 + 12/49

Probability that one fuse is white = 27/49

Therefore, the probability that one fuse is white is 27/49.

The Analytic Hierarchy Process (AHP) can be used to make a decision when selecting a car by considering various criteria and alternatives. AHP provides a structured approach for evaluating and prioritizing different factors.

The AHP method involves breaking down the decision problem into a hierarchy of criteria and sub-criteria. The decision-maker assigns weights to each criterion based on their relative importance. Then, the alternatives (different car options) are evaluated against each criterion, and pairwise comparisons are made to determine their relative performance. These comparisons are converted into numerical values using a scale, such as the Saaty scale, to establish the preference of one alternative over another.

By applying mathematical calculations and aggregating the preferences, the AHP method generates a final ranking of the car alternatives based on their overall performance across the criteria. This enables the decision-maker to select the car that aligns most closely with their preferences and satisfies the desired criteria, considering factors such as price, fuel efficiency, safety features, comfort, reliability, and others.

Answer:

Explanation:

From the information given:

The instantaneous expression of the electric field in the wave is:

\(E(r,t)= (i_x \sqrt{3} -i_z) 2 \ sin (2 \pi*10^8t + 2 \pi x/3+2 \pi z /\sqrt{3} + 30 ^0) , \ V/m\)

To determine the unit vector in line with the wave electric field, we take the first term in E(r,t) for \(I_E^\to\) as:

\(I_E^\to = i_x \sqrt{3}-i_z \\ \\ I_E^\to = \dfrac{i_x \sqrt{3}-i_z}{\sqrt{3 +1}} \\ \\ \mathbf{ I_E = \dfrac{i_x\sqrt{3} -i_z}{2}}\)

The amplitude is denoted by the numerical value after the first term, which is:

\(\mathbf{E_o = 2}\)

The wavelength can be determined by using the expression:

\(\beta =\dfrac{2 \pi}{\lambda }\)

from the given instantaneous expression:

\(\beta = \dfrac{2 \pi}{3}x+\dfrac{2 \pi}{\sqrt{3}}z\)

\(\beta = \sqrt{\dfrac{2 \pi}{(3)^2}+\dfrac{(2 \pi}{(\sqrt{3})^2}}\)

\(\beta = \sqrt{\dfrac{2 \pi}{9}+\dfrac{2 \pi}{{3}}}\)

Factorizing 2π

\(\beta =2 \pi \sqrt{\dfrac{1}{9}+\dfrac{1}{{3}}}\)

\(\beta =2 \pi \sqrt{\dfrac{9+3}{9*3}}}\)

\(\beta =2 \pi \sqrt{\dfrac{12}{27}}}\)

\(\beta =2 \pi \sqrt{\dfrac{4*3}{9*3}}}\)

\(\beta =2 \pi \sqrt{\dfrac{4}{9}}}\)

\(\beta =2 \pi\times {\dfrac{2}{3}}}\)

recall from the expression using in calculating wavelength:

\(\beta =\dfrac{2 \pi}{\lambda }\)

∴

equating both together, we have:

\(\dfrac{2 \pi}{\lambda }= 2 \pi\times {\dfrac{2}{3}}}\)

\(\lambda = \dfrac{3}{2}\)

λ = 1.5 m

In line with the wave direction; unit vector \(i_k\) can be computed as follows:

\(i_k = - [ \beta_1x +\beta_2z]/\beta\)

where;

\(\beta_1 = \dfrac{2 \pi }{3} \ ; \ \beta_2 = \dfrac{2 \pi }{\sqrt{3}} \ ; \ \beta = \dfrac{2 \pi \times 2}{3} ;\)

∴

\(i_k = - \Big[\dfrac{2 \pi}{3}x + \dfrac{2 \pi}{\sqrt{3}} z\Big]\times \dfrac{1}{\dfrac{2 \pi *2}{3}}\)

\(i_k = - \Big[\dfrac{x}{2} + \sqrt\dfrac{{3}}{4}} z\Big]\)

\(i_k = - \Big[\dfrac{1}{2}x + \sqrt{\dfrac{3}{4} }z\Big]\)

\(\mathbf{i_k = - \Big[0.5x +0.86 z\Big]}\)

According to the statement the vertical section at the survey station is -8160.8 ft.

The vertical section at the survey station can be determined by using the formula:Vertical section = (north departure) × (tan azimuth) - (east departure) × (cot azimuth)

where "north departure" refers to the distance traveled in the north direction, "east departure" refers to the distance traveled in the east direction, and "azimuth" refers to the angle between the target point and the north direction in degrees.

Using the given values of north departure, east departure, and azimuth, we get:

Vertical section = (3000 ft) × (tan 24.9°) - (5000 ft) × (cot 24.9°)

Vertical section = (3000 ft) × (0.4794) - (5000 ft) × (1.9198)

Vertical section = 1438.2 ft - 9599 ft

Vertical section = -8160.8 ft (rounded to one decimal place)

Therefore, the vertical section at the survey station is -8160.8 ft.

Since the vertical section is negative, this means that the target point is lower in elevation than the survey station.

Section Key Terms

kinetic friction static friction

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

In engineering, the term "double standard" refers to a situation where two different sets of standards or specifications are applied to similar engineering products or systems.

In software development, testing is the process of evaluating a software application or system to verify that it meets the intended requirements and works as expected. Testing is an important step in the software development life cycle (SDLC), as it helps to identify defects, errors, or vulnerabilities in the software and ensures that the product is of high quality and meets the desired performance standards.

Double standards in engineering can have significant implications for the safety, reliability, and performance of products and systems. They can lead to unequal treatment of manufacturers or suppliers, creating an uneven playing field in the marketplace. This can result in the proliferation of substandard or unsafe products, and erode public trust in the engineering profession as a whole.

To address double standards in engineering, it is essential to ensure that there is a level playing field for all manufacturers and suppliers. This can involve the development of consistent and transparent regulations and standards that are applied equally to all parties. It can also involve the establishment of robust testing and certification processes to ensure that products and systems me et the required specifications.

Additionally, engineers and engineering organizations have a responsibility to be transparent and honest in their communications with regulators, customers, and the public. This includes acknowledging and addressing any double standards that may exist, and taking steps to rectify them.
