Fill in the blank: The direct-current system grounding connection shall be made at any _____ point(s) on the PV output circuit.

Answers

Answer 1

The direct-current system grounding connection shall be made at any accessible point(s) on the PV output circuit.

In a direct-current (DC) photovoltaic (PV) system, grounding is an important safety measure. The grounding connection provides a path for the discharge of electrical faults or surges, reducing the risk of electrical shock and equipment damage. The specific location for the grounding connection is flexible and can be made at any accessible point on the PV output circuit. This allows for flexibility in system design and installation while ensuring the safety and protection of the system and personnel.

Determine the carburizing time necessary to achieve a carbon concentration of 0.30 wt.% at a position of 4 mm into an iron-carbon alloy that initially contains 0.10 wt.% C. The surface concentration is to be maintained at 0.90 wt.% C, and the treatment is to be conducted at C. Use the diffusion data for -Fe in Table 5.2

Answers

Answer:

the carburizing time necessary to achieve a carbon concentration is 31.657 hours

Explanation:

Given the data in the question;

To determine the carburizing time necessary to achieve the given carbon concentration, we will be using the following equation:

(Cs - Cx) / (Cs - C0) = ERF( x / 2√Dt)

where Cs is Concentration of carbon at surface = 0.90

Cx is Concentration of carbon at distance x = 0.30 ; x in this case is 4 mm = ( 0.004 m )

C0 is Initial concentration of carbon = 0.10

ERF() = Error function at the given value

D = Diffusion of Carbon into steel

t = Time necessary to achieve given carbon concentration ,

so

(Cs - Cx) / (Cs - C0) = (0.9 - 0.3) / (0.9 - 0.1)

= 0.6 / 0.8

= 0.75

now, ERF(z) = 0.75; using ERF table, we can say;

Z ~ 0.81; which means ( x / 2√Dt) = 0.81

Now, Using the table of diffusion data

D = 5.35 × 10⁻¹¹ m²/sec at (1100°C) or 1373 K

now we calculate the carbonizing time by using the following equation;

z = (x/2√Dt)

t is carbonizing time

so we we substitute in our values

0.81 = ( 0.004 / 2 × √5.35 × 10⁻¹¹ × √t)

0.81 = 0.004 / 1.4628 × 10⁻⁵ × √t

0.81 × 1.4628 × 10⁻⁵ × √t = 0.004

1.184868 × 10⁻⁵ × √t = 0.004  

√t = 0.004 / 1.184868 × 10⁻⁵

√t = 337.5903

t = ( 337.5903)²  

t = 113967.21 seconds

we convert to hours

t = 113967.21 / 3600

t = 31.657 hours

Therefore, the carburizing time necessary to achieve a carbon concentration is 31.657 hours

Water enters a vertical jet with low velocity and a pressure of 350 kPa. What is the maximum height that the water can rise above the jet

Answers

The maximum height that the water can rise above the jet is: 35 meters.

Maximum height that the water can rise above the jet

Given:

P = 350 kPa = 350000 Pa

We would use pressure(p)  formula to determine the maximum height that the water can rises above the jet by solving for h (height).

Using this formula

Pressure(P) = P₀ + ρgh

Where;

P₀ represent Pressure at the fluid's surface

ρ represent Density of the fluid = 1000 kg/m³

g represent acceleration due to gravity = 10 m/s².

h represent height

Solving for h (height)

350000 = 0 + (1000 × 10 ×h)

350000 = 10000h

Divide both side by  10000h

h = 350000/10000

A +7.5% grade meets a horizontal grade on a section of a rural mountainous highway. If the length of the crest vertical curve formed in that section is 300 ft long, determine the safe operating speed on the highway.

Answers

Using the formula of comfort condition it is possible to determine the safe operating speed on the highway.

What is a deflection angle?

In physics, we define angular deviation as the angle resulting from the deflection of light when reflected from a prism. A prism has the ability to separate white light into several other colors, which are reflected by the object.

The comfort condition formula is given by: [tex]L=2(\frac{NV^{3} }{C} )^{\frac{1}{2} }[/tex]

Where, L is the length of the vertical curve, N is the grade, V is the safe speed operation and assuming the standart value for C (0,6 m/s3) it is possible to calculate:

[tex]C = 0,6 m/s^{3} = 1,968 ft/s^{3}\\ N= N1 - N2 = 7,5-0 = 7,5% = 0,075[/tex]

Changing the values in the formula:

[tex]L=2(\frac{NV^{3} }{C}){\frac{1}{2} } \\300 = 2(\frac{0,075.V^{3} }{1,968})^{\frac{1}{2} } \\V = 83,89 ft/s[/tex]

So, the safe operating speed on the highway is 83,89 ft/s.

Water enters a vertical jet with low velocity and a pressure of 350 kPa. What is the maximum height that the water can rise above the jet

Answers

The maximum height that the water can rise above the jet is; 35 m

How to find the height pressure of water?

The formula for pressure here is;

P = P₀ + ρgh

where;

P₀ is the pressure at the fluid's surface.

ρ is the density of the fluid. (density of water = 1000 kg/m³)

g is the acceleration due to gravity = 10 m/s².

h is height of rise of fluid

Now, the pressure at water surface is zero because the pressure the atmosphere exerts on the water is equal to the pressure the water exerts on the atmosphere. Thus, P₀ = 0 Pa

We are given P = 350 kPa = 350000 Pa. Thus;

350000 = 0 + (1000 * 10 * h)

Answers

The maximum load that may be applied to a specimen with a cross-sectional area of 130 mm² is; 35535 N

How to find Elastic Modulus?

We are told that for an alloy, the yield stress is 345-MPa and the elastic modulus (E) is 103-GPa.

Now, we want to find the maximum load that may be applied to a specimen with a cross-sectional area of 130-mm² without plastic deformation. Thus;

We are given the parameters;

Yield Stress; σ = 345 Mpa = 345 * 10⁶ Pa

Elastic Modulus; E = 103 GPa = 103 * 10⁹ Pa

Cross sectional Area; A = 130 mm² = 103 * 10⁻⁶ m²

Formula for stress without Plastic deformation is;

σ = F_max/Area

where;

σ is stress

F_max is maximum force

Area is Area

Thus making maximum force the subject of the formula gives;

F_max = σ * A

Plugging in the relevant values for stress and area gives us;

F_max = 345 * 10⁶ * 103 * 10⁻⁶

F_max = 35535 N

D) A two-sample t-test for means 20 A) A chi-square goodness of fit test C) A matched-pairs t-test for means E) A linear regression t-test Let be the population mean of excess weight amongst Australians. The hypotheses for the required test are(a) H0 : > 10 against HA : = 10(b) H0 : > 10 against HA : 10(c) H0 : = 10 against HA : > 10(d) H0 : = 10 against HA : 10(e) none of these (a) Derive the mean stock price in the Cox-Ross-Rubinstein model using MGF method. (b) What is the mean and variance of a stock's price after 8 time periods with initial price S, = $100 and parameters u =1.01, d =0.99, and p=0.51?(c) Refer to (b), approximate the probability that the stock's price will be up at least 30% after 1000 time periods. the largest number of advertisements use this approach to grab our attention and appeal to us as consumers: the need for affiliation. true or false determine whether the improper integral diverges or converges. f [infinity]/0 1/e^2x e^-2x dx converges diverges Solve the equation x + x = 132 using a trial and improvement method. You MUST show all your working. assuming that the population was in hardy-weinberg equilibrium for the g locus, what was the frequency of allele g in the gray moths that emerged in 1980? A. 0.33 B. 0.50 C. 0.67 D. 0.75 what type of domain name system (dns) record holds information such as 2001:4860:4860:8888? mergesort is a complicated process, but what is it actually doing? we are going to take a closer look at the process in this exercise. you are given the merge sort algorithm and you need to add some print statements so that you can see what actually is happening.
