Answer:

  (a) 100 V

  (b) 60 Hz

  (c) 95.106 V

  (d) 25 V, 75 V

  (e) 23.776 V, 71.329 V

  (f) see attached

Explanation:

The peak value of the sine function is 1, so the peak value of U is ...

  100·1 = 100 V.

__

The argument of the sine function is 2πft, so f = 120πt/(2πt) = 60 Hz.

__

When t=0.020, the voltage is ...

  U = 100sin(120π·0.020) = 100 sin(2.4π) ≈ 95.106 V

__

The resistors are in the ratio of 1 : 3, so divide the source voltage in that ratio.

The peak voltage across the 5Ω resistor is 1/4 of 100 V, or 25 V.

The peak voltage across the 15Ω resistor is 3/4 of 100 V, or 75 V.

__

The same fractions as in (d) apply to the instantaneous voltage.

The voltage on the 5Ω resistor is 1/4·95.106 V ≈ 23.776 V

The voltage on the 15Ω resistor is 3/4·95.106 V ≈ 71.329 V

Answer:

Actual COP = 5.368

Maximum theoretical COP = 6.368

Explanation:

Given - An ideal vapor compression refrigeration cycle operates with a condenser pressure of 900 kPa. The temperature at the inlet to the compressor is -5oC.

To find -  If this device operates using R134a as the working fluid. Calculate the actual COP of this device as well as the maximum theoretical COP.

Proof -

Given that,

An ideal vapor compression refrigeration cycle operates with a condenser pressure of 900 kPa.

From Refrigerant 134-a Table

At T1 = -5°C

h1 = 247.505 KJ/kg

S1 = 0.93434 KJ/kg

At P2 = 900 KPa

S1 = S2

h2 = 274.679 Kj/Kg

h3 = h4 = 101.61 KJ/g

So,

Compressor work (Wc) = h2 - h1

                                       = 274.679 - 247.505

                                       = 27.174

⇒Compressor work (Wc) = 27.174 KJ/kg

Now,

Heat out (Qout) = h2 - h3

                          = 274.679 - 101.61

                          = 173.069

⇒Heat out (Qout) = 173.069 KJ/kg

Now,

Heat input (Qin) = h1 - h4

                          = 274.505 - 101.61

                          = 145.895

⇒Heat input (Qin) = 145.895 KJ/kg

So,

Actual COP at the refrigerator is -

(COP)R = (Qin)/(Wc)

            = (145.895)/ (27.174)

            = 5.368

⇒Actual COP = 5.368

Now,

Maximum theoretical COP is -

(COP) = (Qout)/(Wc)

          = (173.069)/ (27.174)

          = 6.368

⇒Maximum theoretical COP = 6.368

The appropriate feature engineering step for binning would be:

a. When we want to create defined groups from a continuous feature.

Binning is a useful technique in feature engineering when we want to convert a continuous feature into discrete or categorical groups. It involves dividing the range of values of a continuous feature into bins or intervals and assigning each value to a corresponding bin. This allows us to create defined groups or categories based on the values of the continuous feature.

Binning can be beneficial in various scenarios. For instance, it can help simplify complex data patterns, handle outliers or noise, and capture non-linear relationships between the feature and the target variable. Binning can also be used to address issues related to model complexity, data sparsity, or limited sample sizes.

By transforming a continuous feature into discrete groups, binning can enable models to capture patterns and make predictions based on the created categories. It allows for a more interpretable representation of the data and can improve the performance of certain machine learning algorithms, especially those that work better with categorical or ordinal data.

In summary, binning is an appropriate feature engineering step when we want to create defined groups or categories from a continuous feature. It can help simplify complex data patterns, handle outliers, and capture non-linear relationships, ultimately enhancing the modeling and prediction capabilities of machine learning algorithms.

In other words, it ensures that all instances of the superclass are covered by at least one subtype of the generalization. An example of how the exhaustion rule works in the company entity type modeling:

Consider the company entity, which can have two subtypes: Hotel Company and Insurance Company. There are no other subtypes. The exhaustion rule implies that every company must be either a Hotel Company or an Insurance Company or both. In this case, each company is identified as being one or both of the subtypes, ensuring that all companies are accounted for and that there are no company instances that are not part of the subtype.

Using α = 0.4, the forecasted sales for 2011, 2012, and 2013 would all be $48,000, which is the same as the actual sales in 2009.

Using α = 0.8, the forecasted sales for 2011, 2012, and 2013 would also be $48,000.

In both cases, the forecasts for 2011, 2012, and 2013 remain the same as the actual sales in 2009 due to the zero difference between the actual and forecasted sales values.

To forecast sales for 2011, 2012, and 2013 using exponential smoothing, we need to apply the formula:

Forecast for the next period = Previous period's forecast + α * (Actual value - Previous period's forecast)

Given that the actual 2009 sales are $48,000 and are considered the forecast for 2010, we can calculate the forecasts for subsequent years using different values of α.

(a) For α = 0.4:

- Forecast for 2011 = $48,000 + 0.4 * ($48,000 - $48,000) = $48,000

- Forecast for 2012 = $48,000 + 0.4 * ($48,000 - $48,000) = $48,000

- Forecast for 2013 = $48,000 + 0.4 * ($48,000 - $48,000) = $48,000

Using α = 0.4, the forecasted sales for 2011, 2012, and 2013 would all be $48,000, which is the same as the actual sales in 2009.

(b) For α = 0.8:

- Forecast for 2011 = $48,000 + 0.8 * ($48,000 - $48,000) = $48,000

- Forecast for 2012 = $48,000 + 0.8 * ($48,000 - $48,000) = $48,000

- Forecast for 2013 = $48,000 + 0.8 * ($48,000 - $48,000) = $48,000

Using α = 0.8, the forecasted sales for 2011, 2012, and 2013 would also be $48,000.

Therefore, the minimum protrusion we would expect for 93.3% (30) of assembled parts is 2.65 mm.

To answer this question, we need to first understand what is meant by "protrusion". Protrusion refers to the amount of the bolt that extends beyond the bottom of the nut once the clamp is fully assembled.
Given that 93.3% (30) of the parts meet the tolerances shown, we can assume that there will be some variation in the assembled parts. In other words, not all assembled parts will be exactly the same.
To determine the minimum protrusion we would expect for this share of assembled parts, we need to consider the worst-case scenario, which is when all the tolerances stack up against us.
The tolerances shown in the diagram indicate that the thickness of the four materials can vary by up to ±0.1mm, and the height of the nut can vary by up to ±0.05mm. This means that the total height of the assembled parts can vary by up to ±0.4mm (4 x 0.1mm), and the height of the nut can vary by up to ±0.05mm.

To calculate the minimum protrusion, we need to consider the case where the nut is at its maximum height tolerance (+0.05mm), and the four materials are at their minimum thickness tolerance (-0.1mm each, for a total of -0.4mm). This would result in the total height of the assembled parts being -0.35mm (i.e., lower than the nominal height of the clamp).

To ensure that the bolt always protrudes from the bottom of the nut, we need to add the height of the nut to the total height of the assembled parts. In this worst-case scenario, the total height would be:
-0.35mm (total height of assembled parts) + 3mm (height of nut) = 2.65mm
Therefore, the minimum protrusion we would expect for 93.3% (30) of assembled parts is 2.65mm.
