HELPP!!! Calculating voltage drop

Answer:

The initial speed need is 6.7689 m/s

Explanation:

 Given the data in the question;

first we determine the acceleration due to gravity in the distant planet;

g = F / m

given that; m = 55 kg and F = 180 N

g = 180 / 55

g = 3.2727 m/s²

Now, the relation between chasm distance and the initial speed;

d = v₀²sin2∅ / g

where d is the width of the chasm

we solve for  v₀

v₀²sin2∅ = gd

v₀² = dg / sin2∅

v₀ = √[ gd / sin2∅ ]

so we substitute in our values;

v₀ = √[ (3.2727×7.0 ) / sin2(15°) ]

v₀ = √[ (22.9089 ) / sin( 15° + 15°) ]

v₀ = √[ (22.9089 ) / sin( 30°) ]  

v₀ = √[ (22.9089 ) / 0.5 ]  

v₀ = √[ 45.8178 ]

v₀ = 6.7689 m/s

Therefore, The initial speed need is 6.7689 m/s

reactive power = 1.915 Var

power factor = 0.64 ( leading )

Explanation:

i) complex power

P = Vrms *  Irms

  = 17.67∠40°  * 0.1414∠-10°

  = 2.5∠50° VA

ii) Apparent power

s = Vrms * Irms

  = 17.67 * 0.1414

  = 2.5 VA

iii) Average power absorbed

Absorbed power ( p )  = Vrms * Irms * cos∅

  = 17.67 * 0.1414  * cos ( 50 )

  = 1.6 watt

iv) Reactive power

P =  Vrms * Irms * sin∅

  = 17.67 * 0.1414  * sin ( 50 )

  = 1.915 VAR

v) power factor

P.F = cos ∅ = p /s

                   = 1.6 watt / 2.5 VA  = 0.64.

A Bode plot is a graphical representation of the frequency response of a system, and it provides valuable insights into the behavior of the system at different frequencies. In non-unity feedback systems, the feedback signal is not the same as the input signal, and the transfer function of the system can be expressed as H(s) = G(s) / (1 + H(s)F(s)), where G(s) is the open-loop transfer function and F(s) is the feedback transfer function.

To sketch a Bode plot of a non-unity feedback system, you need to follow these steps:

1. Determine the open-loop transfer function G(s) and the feedback transfer function F(s).
2. Multiply G(s) by 1 + H(s)F(s) to get the overall transfer function H(s).
3. Convert H(s) into its frequency domain equivalent H(jw).
4. Plot the magnitude and phase of H(jw) as a function of frequency (w) on a log-log scale.
5. Identify the frequency at which the magnitude of H(jw) crosses 0 dB (the gain crossover frequency) and the phase of H(jw) crosses -180 degrees (the phase crossover frequency).
6. Draw a straight line from the gain crossover frequency to the low-frequency asymptote and from the phase crossover frequency to the high-frequency asymptote.

In summary, sketching a Bode plot of a non-unity feedback system involves determining the transfer function, converting it to its frequency domain equivalent, and plotting the magnitude and phase on a log-log scale. By analyzing the plot, you can gain insights into the system's behavior at different frequencies and identify any frequency-dependent problems that may need to be addressed.

To sketch a Bode plot of a non-unity feedback system, you must first determine the transfer function of the system.

This can be done by applying the feedback rule to the open-loop transfer function. Once you have the transfer function, you can use the Bode plot technique to determine the frequency response of the system. A Bode plot consists of two plots: one for the magnitude response and one for the phase response.
To draw the magnitude plot, you can convert the transfer function to its polar form and plot the magnitude (in decibels) versus the frequency (in radians per second) on a logarithmic scale. You can then identify the corner frequencies, where the slope of the magnitude plot changes. These corner frequencies correspond to the poles and zeros of the transfer function.
To draw the phase plot, you can plot the phase angle (in degrees) versus the frequency (in radians per second) on a logarithmic scale. You can identify the phase shift at each corner frequency and at the crossover frequency, where the phase angle is -180 degrees.
Once you have both plots, you can combine them to create the Bode plot. The Bode plot shows how the magnitude and phase of the system response change with frequency. This information can be used to analyze the stability and performance of the system.

Answer:

Shelf life.

Explanation:

In Business, an inventory is a term used to describe a list of finished goods, goods still in the production line and raw materials that would be used for the manufacturing of more goods in a bid to meet the unending consumer demands.

Simply stated, an inventory can be classified into three (3) main categories; finished goods, work in progress, and raw materials.

An inventory is recorded as a current asset on the balance sheet because it's primarily the most important source of revenue for a business entity.

Also, the three (3) main cost concept associated with an inventory are;

1. First In First Out (FIFO).

2. Last In First Out (LIFO).

3. Weighted average cost.

Shelf life can be defined as a measure of the length of time that a particular product could be kept or stored without it getting bad or becoming unsuitable for use by the consumers. Thus, the shelf life of a product is largely dependent on its expiration date.

Hence, merchandise without an expiration date like electronics, tools and home goods typically have a longer shelf life.

Answer & Explanation:

i) If a student foolishly decides to binge drink 21 beers on their 21st birthday, they would consume a total of 21 x 170 = <<21*170=3570>>3570 calories of digestible energy. Since one calorie is equivalent to raising the temperature of one gram of water by one degree Celsius, and one gallon of water is equivalent to 3,785 grams, the student would have consumed enough energy to raise the temperature of 3,785 grams x 3570 calories = 13,678,950 calories of water from 24 °C to 100 °C. This means that the student could have heated 13,678,950 / 100 = <<136789500/100=136789.5>>136789.5 grams of water from room temperature to boiling, which is equivalent to 136789.5 / 3,785 = <<136789.5/3785=36.19>>36.19 gallons of water.

ii) The energy equivalent of the beer consumed by the student is 3570 calories x 4.184 joules/calorie = 14,889.48 joules. Since one BTU is equivalent to 1,055 joules, this energy is equivalent to 14,889.48 joules / 1,055 joules/BTU = <<14889.48/1055=14.15>>14.15 BTU.

iii) If the student had purchased an equivalent amount of electrical energy from the utility company, they would have to pay 14.15 kW-hr x $0.10/kW-hr = $<<14.15*0.1=1.42>>1.42. This is cheaper than buying beer, as a can of beer typically costs more than $1.42.

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

Answer:

a) the heat exchanger area required for the evaporator is 11178.236 m²

b) the required flow rate is 1993630.38 kg/s

Explanation:

Given the data in the question;

Water temperature near the surface = 300 K

temperature at reasonable depths ( cold ) = 280 K

power plant output W' = 2 MW

efficiency η = 3% = 0.03

we know that; efficiency η = W'\(_{power-out\) / Q\(_{supplied\)

we substitute

0.03 = 2 / Q\(_{supplied\)

Q\(_{supplied\) = 2 / 0.03

Q\(_{supplied\) = 66.667 MW = 66.667 × 10⁶ Watt

T\(h_{in\) = 300 K       T\(h_{out\) = 292 K

T\(c_{in\) = 290 K       T\(c_{out\) = 290 K    

Now, Heat transfer in evaporator;

Q = UA( LMTD )

so

LMTD = (ΔT₁ - ΔT₂) / ln( ΔT₁ / ΔT₂ )

first we get ΔT₁ and ΔT₂

ΔT₁ = T\(h_{in\) - T\(c_{out\)  = 300 - 290 = 10 K

ΔT₂ = T\(h_{out\) - T\(c_{in\)  = 292 - 290 = 2 K

so we substitute into our equation;

LMTD = (10 - 2) / ln( 10 / 2 )

LMTD = 8 / ln( 5 )

LMTD = 8 / 1.6094379

LMTD = 4.97

a) Heat transfer Area will be;

Q\(_H\) = UA( LMTD )

we substitute

66.667 × 10⁶ = 1200 × A × 4.97

66.667 × 10⁶  = 5964 × A

A = (66.667 × 10⁶) / 5964

A = 11178.236 m²

Therefore, the heat exchanger area required for the evaporator is 11178.236 m²

b) Flow rate  

we know that;

Q\(_H\) = m'C\(_P\)( \(T_{in\) - \(T_{out\) )  

specific heat capacity of water Cp = 4.18 (kJ/kg∙°C)

we substitute

66.667 × 10⁶ = m' × 4.18 × ( 300 - 292 )

66.667 × 10⁶ = m' × 33.44

m' = ( 66.667 × 10⁶ ) / 33.44

m' = 1993630.38 kg/s

Therefore, the required flow rate is 1993630.38 kg/s
