A simple gas turbine cycle operates with an overall pressure ratio of 6, the compression inlet condition being 1.013bar and 288K and the turbine inlet temperature is 700°C. Assuming the working fluid is air with the flow rate of 10kg/s, calculate:

a. The compressor work b. The turbine work

c. The heat supplied

d. The thermal efficiency​

A saturated soil with a mass of 43.2g. When dried in the oven its mass was 30g, the limit of contraction is 0.4.

For the limit of contraction, we know that:

Limit of contraction (Lc) = (Vw - Vd) / Vw

Lc = (20 - 12) / 20

Lc = 8 / 20

Lc = 0.4

Therefore, the limit of contraction is 0.4.

Now for the dry weight,

Dry unit weight (γd) = γw / (1 + e)

e = (Gs - 1) / Gs

n = e / (1 + e)

w = (wet weight - dry weight) / dry weight

In this case,

γw = 9.81 kN/\(m^3\)

Gs = 2.74.

So,

γd = 2010 / (1 + ((2.74 - 1) / 2.74))

γd = 2010 / (1 + 0.727)

γd = 2010 / 1.727

γd = 1163.54 kg/m^3

e = (2.74 - 1) / 2.74

e = 1.74 / 2.74

e ≈ 0.635

n = 0.635 / (1 + 0.635)

n = 0.635 / 1.635

n ≈ 0.388

w = (43.2 - 30) / 30

w = 13.2 / 30

w ≈ 0.44

Therefore, the dry unit weight (γd) is approximately 1163.54 kg/m^3, the void ratio (e) is approximately 0.635, the porosity (n) is approximately 0.388, and the moisture content (w) is approximately 0.44.

You should wait at least 24 hours before staining pressure treated wood. This will give the wood time to dry out and the chemicals to cure. If you stain the wood too soon, the stain may not penetrate the wood properly and may not last as long.

Pressure treated wood is treated with chemicals to protect it from rot, decay, and insects. These chemicals can make the wood wet and can also make it difficult for stain to penetrate. If you stain the wood too soon, the stain may not be able to penetrate the wood properly and may not last as long.

To determine if the pressure treated wood is dry enough to stain, you can try the "sprinkle" test. Sprinkle water on the wood. If the water beads or pools on the surface, the wood is not dry enough to stain. If the water is absorbed within 10 minutes, the wood is dry enough to stain.

It is also important to consider the weather conditions when staining pressure treated wood. If it is hot and humid, the wood may not dry as quickly. If it is raining, you should not stain the wood at all.

By waiting at least 24 hours before staining pressure treated wood, you can help to ensure that the stain will penetrate the wood properly and will last as long as possible.

The change in annual cost when Q is increased from 340 to 341 is -1.23 and the instantaneous rate of change when Q = 340 is -1.25

The annual inventory cost C for a manufacturer is given as;

C = (1012000/Q) + 7.5Q

where Q is the order size when the inventory is replenished.

Now, the change in C can be calculated by evaluating the cost function at Q = 340 and Q = 341

Change in C = [1,012,000/341 + 7.5*341] - [1,012,000/340 + 7.5*340] ≈ -1.23

Instantaneous rate of change in C is first order derivative C':

C'(Q) = -1,012,000/(Q²) + 7.5

C'(340) = -1,012,000/(340²) + 7.5 ≈ -1.25

Answer:

778.4°C

Explanation:

I = 700

R = 6x10⁻⁴

we first calculate the rate of heat that is being transferred by the current

q = I²R

q = 700²(6x10⁻⁴)

= 490000x0.0006

= 294 W/M

we calculate the surface temperature

Ts = T∞ + \(\frac{q}{h\pi Di}\)

Ts = \(30+\frac{294}{25*\frac{22}{7}*\frac{5}{1000} }\)

\(Ts=30+\frac{294}{0.3928} \\\)

\(Ts =30+748.4\\Ts = 778.4\)

The surface temperature is therefore 778.4°C if the cable is bare

An environmental hazard is a substance, state or event which has the potential to threaten the surrounding natural environment and/or adversely affect human's health. This term incorporates topics like pollution, natural disasters and human-made hazards. Health studies investigate the human health effects of exposure to environmental hazards ranging from chemical pollutants to natural, technological or terrorist disasters. The environment in which we live can be considered as having three fundamental sets of components, physical, chemical, biological. Associations between an exposure and an adverse health effect do not, on their own, prove that the former is the cause of the latter. Many other non-causal associations could explain the findings. Physical hazards involve environmental hazards that can cause harm with or without contact. Examples are earthquakes, electromagnetic fields, floods, light pollution, noise pollution, vibration, x-rays etc. Radioactivity is associated with an exposure dependent risk of some cancers notably leukaemia. The scientific evidence of adverse health effects from general environmental exposure to these fields is "not proven". If there are adverse effects yet to be proven, the risk is probably likely to be small. Chemical substances cause significant damage to the environment. Tobacco smoke is the single biggest known airborne chemical risk to health, whether measured in terms of death rates or ill-health. To a much lesser degree of risk, these adverse effects apply to non-smokers exposed passively to sidestream tobacco smoke. Health effects of concern are asthma, bronchitis, lung cancer and similar lung diseases, and there is good evidence relating an increased risk of symptoms of these diseases with increasing concentration of Sulphur dioxide, ozone and other pollutants. Biohazards generally fall into two broad categories: those which produce adverse health effects through infection (microorganisms, viruses or toxins) and those which produce adverse effects in non-infective (allergic) ways.

Answer:

A

Explanation:

Calculating the flow rate through a pipe can be done using the pipe's cross-sectional area and the pressure difference between the two ends of the pipe. The first step is to determine the pipe's cross-sectional area, which can be calculated using the pipe's diameter.

Once the area is determined, the pressure difference between the two ends of the pipe is measured using a pressure gauge. By using Bernoulli's equation, the flow rate can then be calculated. Bernoulli's equation states that the pressure difference is equal to the fluid's density times the velocity squared times one-half of the cross-sectional area. If the velocity is not known, it can be calculated using the mass flow rate and the density of the fluid. Therefore, by knowing the cross-sectional area, pressure difference, density, and mass flow rate, the flow rate through a pipe can be calculated.

cost of ownership for the Switch LED Lightbulb is $94.99.

To calculate the cost of ownership for the Switch LED Lightbulb, we need to first determine the total electricity cost.  We know that the bulb uses 20 watts of electricity and is estimated to last 25,000 hours. To find the total electricity cost, we need to multiply the wattage by the hours of use and the cost of electricity per kW-hr.
20 watts x 25,000 hours = 500,000 watt-hours
500,000 watt-hours ÷ 1,000 = 500 kWh
500 kWh x $0.086/kWh = $43.00
So the total electricity cost for the Switch LED Lightbulb is $43.00.
Next, we need to add the purchase price of $51.99 to the total electricity cost of $43.00:
$51.99 + $43.00 = $94.99
Therefore, the  correct answer is c. $94.99.

Answer:

A) 211.81 m

B) 65°

Explanation:

We are told that the first friend hits a golf ball on level ground with an initial speed of 47 m/s at an angle of 35° above the horizontal.

Thus;

speed; u = 47 m/s

Projection angle; θ = 35°

A) We want to find how far away from the golfer the ball lands. This is simply the range. Range in projectile motion is given by the formula;

R = (u²•sin 2θ)/g

Plugging in the relevant values, we have;

R = (47² × sin(2 × 35))/9.8

R = 211.81 m

B) We are told that the second ball, travels the same horizontal distance as what is found in part (a).

Thus, R remains 211.81 m

Thus, the angle above horizontal of the initial velocity of this second golf ball will be;

90° - projection angle(θ) = 90 - 35 = 65°

Art Text Questions

Question one: There were seven elements of the design listed in the unit. Please name five of them, and give a short description of each.

Answer: line, shape, space, value, form, texture, and color.

Line: I thin or thick drawn/made considered a moving point in space, It is one-dimensional and can vary in width, direction, and length.

Shape: a two-dimensional form tends to be colored or circled/lined

Space: the feeling of depth or three dimensions there’s a positive and negative space, Positive space is filled in or used to be a part of the drawing, the negative can be the empty space in the painting

Value: it sometimes light and dark colors it is used a scale at times and used to make high or low contrast

Form: has a physical being and the other could be like a message from an image,

Textures: surface quality, there are real and actual textures, some textures aren't as they seem or made something created to look like something it is not

Color: the element of art

Question two: There were also seven principles of the design listed in the unit. List five of the principles of design and explain what each means.

Answer: Emphasis, contrast, balance, pattern, and rhythm.

Emphasis: The principle of art that helps the audience put the story of a painting together in their own minds. Any object or area of emphasis is called a focal point.

Contrast: The arrangement of opposite elements and effects. For example, light and dark colors, smooth and rough textures, large and small shapes.

Balance: The distribution of the visual weight of objects, colors, texture, and space.

Pattern: A design in which lines, shapes, forms, or colors are repeated.

Rhythm: The principle of design that suggests movement or action.

Question three: There are three different ways that balance is used. Please list the three different ways and explain what each means.

Answer: Symmetrical, asymmetrical, and radial

Balance is the principle of design that teaches the work of art should be in harmony, and that its sides “weigh” the same so that it doesn’t look uneven. The three types of balance are symmetrical, asymmetrical, and radial.

Symmetrical balance means the two parts of the art are identical. If we were to separate the picture or art piece in the middle, the two sides would be equal, presenting the same elements and weighing the same.

An asymmetrical balance occurs when the two parts of the painting or work of art are not the same, yet they weigh the same. They are in harmony, but they have different components. For example, maybe one side presents larger elements, but the other side has brighter colors, so there is no tension, and the observer sees composure on the piece.

Radial balance is presented as elements gathered around the joined center. They can go towards it, or from it, but they seem as if to radiate from the same point.

Question four: In the unit, elements of content were discussed. There were four elements of content listed; please name all four and write one sentence explaining each?

Answer: line, shape, form, and texture

Line: Lines, a line is the starting point of every artist's artwork, the line could either be broken, jagged, vertical, horizontal, or diagonal, so basically, a line is the start of the art.

Shape: A shape is anything with edges or is surrounded by an outline, a shape can be anything, but it just has to all end and connect at a certain point to make it a certain shape you want, or you can make your own shape!
