Which one step up the voltage to a range of 138000 765000 volts?

Answers

Answer 1

The most efficient way to step up the voltage from 138000 to 765000 volts would be to use a transformer.

What is voltage?

Voltage is an electrical potential difference between two points in an electrical circuit. It is measured in volts (V) and is the amount of electrical energy that can push electrons through a conductor, such as a wire. Voltage can be thought of as the pressure that causes electrons to flow.

A transformer is an electrical device used to transfer electrical energy between two or more circuits by means of electromagnetic induction. It works by changing the voltage of an AC electrical signal by using the principles . By connecting the primary winding of a transformer to a \(138000 V AC\) source, and the secondary winding to a\(765000 V AC\) load, the voltage can be increased from \(138000\) to \(765000\) volts.

if the height of a 12 in. wide rectangular beam section is increased from 16 in. to 32 in. (i.e., initial section is 12x16 in. and final section is 12x32 in.), the maximum flexure or bending stress in the beam becomes?

Answers

The maximum flexure or bending stress in the beam is increased by a factor of 4.

The maximum flexure or bending stress in a beam is calculated using the equation:

σ = Mc/I

Where,

σ = Maximum flexure or bending stress (MPa)

M = Maximum bending moment (N.m)

c = Distance from Neutral Axis to outermost fibre (mm)

I = Moment of Inertia (mm4)

For the given beam,

Initial Section: 12 x 16 in.

Final Section: 12 x 32 in.

For the initial section:

I1 = b1 x h12^3/12 = 12 x 162^3/12 = 24576 in4

For the final section:

I2 = b2 x h22^3/12 = 12 x 322^3/12 = 98304 in4

Therefore, the Moment of Inertia (I) is increased by a factor of 4 (I2 = 4 x I1).

Since M and c remain unchanged, the maximum flexure or bending stress (σ) is increased by a factor of 4 (σ2 = 4 x σ1).

Acme Logistics provides "Less than truck load" (LTL) services throughout the U.S. They have several hubs where they use cross-docking to move goods from one trailer to another. Acme built its last hub 10 years ago, and it had 36 dock doors. The cost index at that time was 140, and the total cost was $6 million. Acme plans a new hub that will have 48 dock doors. The cost index now is 195, and Acme will use a capacity factor of 0.82. What is the estimated cost of the new hub?

Answers

Answer:

The answer is "$10.12 million"

Explanation:

To find the price of the 36 dock doors only at the current rate, just use the cost index.  

\(C_n=C_k \times (\frac{I_n}{I_k})\\\\\)

     \(= 6 \times \frac{195}{140} \\\\= \$ \ 8 \ million\)

Its current cost of 36 dock doors is, thus,\(\$ \ 8 \ million\). To calculate the price for 48 dock doors, just use the second formula now:

\(\to (\frac{C_A}{C_B})=(\frac{S_A}{S_B})^{X}\\\\\to C_A=C_B \times (\frac{S_A}{S_B})^{X}\\\\\)

         \(=8 \times (\frac{48}{36})^{0.82}\\\\= \$ 10.12 \ million\)

a commercial refrigerator with r-134a as the working fluid is used to keep the refrigerated space at -35 c by rejecting waste heat to cooling water that enters the condenser at 18 c at a rate of 0.25 kg/s and leaves at 26 c. the refrigerant enters the condenser at 1.2 mpa and 50 c and leaves at the same pressure subcooled by 6 c. if the compressor consumes 3.3 kw of power , determine (a) the mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.

Answers

At 1.2mpa pressure and 50c

What is pressure?
By pressing a knife against some fruit, one can see a straightforward illustration of pressure. The surface won't be cut if you press the flat part of the knife against the fruit. The force is dispersed over a wide area (low pressure).

a)Mass flow rate of the refrigerant
Therefore h1= condenser inlet enthalpy =278.28KJ/Kg
saturation temperature at 1.2mpa is 46.29C
Therefore the temperature of the condenser

T2 = 46.29C - 5
T2 = 41.29C

Now,
d)power consumed by compressor W = 3.3KW
Q4 = QL + w = Q4
QL = mR(h1-h2)-W
= 0.0498 x (278.26 - 110.19)-3.3
=5.074KW
Hence refrigerator load is 5.74Kg

(COP)r = 238/53
(Cop) = 4.490

Therefore the above values are the (a) mass flow rate of the refrigerant, b) the refrigerant load, c) the cop, and d) the minimum power input to the compressor for the same refrigeration load.

2..Three formations, each 25 m thick, overlie one another. If a constant-velocity vertical flow field is set up across the set of formations with h = 120 m at the top and h = 100 m at the bottom, calculate h at the two internal boundaries. The hydraulic conductivity of the top formation is 0.0001 m/s, the middle formation 0.0005 m/s, and the bottom formation 0.0010 m/s.

Answers

The values of h at the two internal boundaries are :

h₁ = 104.625 m h₂ = 101.55 m

Given data :

Z₁ = Z₂ = Z₃ = 25 m

h top = 120 m

h bottom = 100 m

K₁ = 0.0001 m/s

K₂ = 0.0005 m/s

K₃ = 0.0010 m/s

First step : Calculate the value of Keq

we will apply the formula below since flow is perpendicular to the bedding plane

Keq = \(\frac{Z1 + Z2 + Z3 }{\frac{Z1}{K1}+\frac{Z2}{K2} + \frac{Z3}{K3} }\)  ----- ( 1 )

Insert values given above into equation 1

Therefore ; Keq = 2.307 * 10⁻⁴ m/s

Next step : determine the hydraulic gradient

Hydraulic gradient ( Ieq ) = head loss / length

                                          = ( 120 - 100 ) / 3 * 25

                                   Ieq  = 0.266

Given that the flow is perpendicular to bedding plane

q1 = q2 = q3

V₁ = V₂ = V₃ = V

K₁i₁ = K₂i₂ = K₃i₃ = Keq * ieq

Hence :

V = Keq* Ieq

   = 2.307 * 10⁻⁴ * 0.266

   = 6.15 * 10⁻⁵ m/s .

Also;

K₁i₁ =  Keq * ieq = K₂i₂ = K₃i₃

therefore :

  i₁ = 0.615

  i₂ =  0.123

  i₃ = 0.0615

Final step : determine the value of h at the two internal boundaries

Pressure at point 1 ( i.e. pressure between first two formations )

h₁ = h top - i₁L₁

   = 120 - 0.615 * 25

   = 104.625 m

Pressure at point 2 ( i.e. pressure between the 2nd and 3rd formation )

h₂ = h₁ - i₂L₂

    = 104.625 - 0.123 * 25

    = 101.55 m

Therefore we can conclude that The values of h at the two internal boundaries are :  h₁ = 104.625 m , h₂ = 101.55 m

3. a nominal passband gain of 20 dB, which drops to 14 dB at the cutoff frequency
Write the formula for H(s) that satisfies these requirements.

Answers

Answer:

H(s) =  10 / [ 1 + s / (200*10^3π ) ]^2

Explanation:

Characteristics of the high pass filter

Cutoff frequency = 100 kHz

stopband attenuation rate = 40 dB/decade

nominal passband gain = 20dB  = 20logK = 20

Formula for H(s) satisfying the requirements above

given that the stopband attenuation = 40 dB/decade the formula for H(s) that will satisfy the requirements is a second order filter

H(s) = K / ( 1 + s/Wo ) ^2  ----- ( 1 )

Wo = 2πf = 2π ( 100 * 10^3 ) =  200 * 10^3 π

 K = 10

What might the effect of using salt on snowy and icy roads be on Montgomery County's Water Supply?" What might the effect of using salt on snowy and icy roads be on Montgomery County's Water Supply?"

Answers

The use of salt on snowy and icy roads could have a negative effect on Montgomery County's Water Supply. The salt used on the roads for melting ice can cause a number of issues for water supplies and ecosystems, and Montgomery County is no exception.

When salt is used to melt snow and ice on the road, it can dissolve into the water and run off into streams, rivers, and lakes. The salt lowers the freezing point of water and melts ice, but it also alters the chemical makeup of the water, making it more saline.

Determine the gage pressure at the center of pipe A in pounds per square inch and

in kilopascals.

Answers

Answer: the stress is 384 pounds per square inch.

Step-by-step explanation:

Let S represent the stress in the material of the pipe.

Let P represent internal pressure of the pipe.

Let D represent internal diameter of the pipe.

Let T represent the thickness of the pipe.

The stress in the material of a pipe subject to internal pressure varies jointly with the internal pressure and the internal diameter of the pipe and inversely with the thickness of the pipe. Introducing a constant of proportionality, k, the expression becomes

S = kPD/T

The stress is 100 pounds per square inch when the diameter is 5 inches, the thickness is 0.75 inch, and the internal pressure is 25 pounds per square inch. It means that

100 = (k × 25 × 5)/0.75

125k = 100 × 0.75 = 75

k = 75/125 = 0.6

The equation representing the relationship becomes

S = 0.6PD/T

If the internal pressure is 40 pounds per square inch, the diameter is 8 inches and the thickness is 0.50 inch, then the stress would be

S = (0.6 × 40 × 8)/0.5

S = 384

Explanation:

what could happen if the engine was uncowled during the starting and operating procedures

Answers

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity.

What is the engine starting procedure?

Closing the throttle, turning off the fuel pump, setting the mixture control to idle cutoff, and simply cranking the engine is the most reliable hot start method I've found.

What is the procedure for engine failure?

If an engine fails during rollout or just before takeoff, immediately shut both throttles and land the aircraft safely. Before reaching a safe single engine speed right away after takeoff, drop your nose to increase velocity. If you are unable to climb, close both throttles and land straight ahead.

What happens if engine fails during take off?

The typical practice for the majority of aircraft would be to abandon takeoff if an engine failed during takeoff. In small aircraft, the pilot should turn the throttles down to idle, activate the speed brakes (if provided), and apply the brakes as needed if the engine fails before VR (Rotation Speed).

A doctor is deciding how to treat a given disease. the doctor will precribe one medication, one dietary change, and one type of vitamin supplement. there are five medications, five dietary changes, and five types of vitamins the doctor might prescribe. how many combina-tions are possible?

Answers

The total combinations are possible is 125 combinations.

We need to know about math combinations to solve this problem. The combination is the number of ways to choose a sample of r elements from a set of n distinct objects where order does not matter and replacements are not allowed. It can be written as

nCr = n! / (r!(n-r)!)

where n is object and r is a sample

From the question above, we know that

1  vitamin supplement chosen has combination

5C1 = 5! / 1!(5-1)! = 5 combination

1 meditation chosen has combination

5C1 = 5! / 1!(5-1)! = 5 combination

and 1 dietary chosen has combination

5C1 = 5! / 1!(5-1)! = 5 combination

Hence, the total combination is

C = Cvitamin x Cmeditation x Cdietery

C = 5 x 5 x 5

C = 125 combinations
