The design process that can help avoid the need to resolve higher forms of normalization is the normalization by synthesis approach.

This approach involves designing systems or components from scratch using predefined design rules and guidelines that inherently incorporate normalization principles. Normalization is a process used in database design to eliminate data redundancy and improve data integrity. Higher forms of normalization, such as third normal form (3NF) or Boyce-Codd normal form (BCNF), can become necessary when dealing with complex data structures and relationships. However, to avoid the need for resolving higher forms of normalization, the normalization by synthesis approach can be employed.

In the normalization by synthesis approach, the design process starts from scratch by synthesizing systems or components using predefined design rules and guidelines. These rules and guidelines are already designed to incorporate normalization principles, ensuring that the resulting system or component is inherently normalized up to a certain level. By following this approach, data redundancy and anomalies are minimized from the beginning, reducing the likelihood of needing to address higher forms of normalization later on.

Explanation:

The pressure in the steam line is 1,44 atm.

Streamlined defined as a graph showing the pressure at which a liquid and its vapor are in equilibrium at any temperature. Steam pressures and temperatures in current practice have reached 97–164 bar and 480–565°C or 593°C. The rate of enhancement in efficiency with enhancement in pressure becomes less as the pressure enhances. The steam work through from the boiler into the steam mains. Firstly, the pipework is cold and heat is transformed into it from the steam. The air surrounding the pipes is also cooler rather than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.

The height of a steam gauge = 15 ft = 4,572 m

the gauge reads 450 psi

1 psi = 14.7 atm

450 psi = 6,615 atm

We can use this formula to calculate the pressure:

P = F/h

Pressure (P) = 6,615 atm : 4,572 m = 1,44 atm

(a) The machine's average hourly production rate without considering availability is 6.02 parts/hr.

(b) The machine's average hourly production rate, taking into account availability, is 6.17 parts/hr.

(c) The machine's average hourly production rate when only available during run time is 5.71 parts/hr.

(a) To calculate the average hourly production rate of the machine without considering availability, we need to first calculate the total time it takes to produce a batch of 52 parts.

Total time = (setup time) + (operation time per part x batch size)

Total time = 5.0 hr + (4.2 min/part x 52 parts)/60 min/hr

Total time = 5.0 hr + 3.64 hr

Total time = 8.64 hr

Average hourly production rate = Batch size / Total time

Average hourly production rate = 52 parts / 8.64 hr

Average hourly production rate = 6.02 parts/hr

Therefore, the average hourly production rate of the machine without considering availability is 6.02 parts/hr.

(b) To calculate the average hourly production rate of the machine taking into account availability, we need to first calculate the machine's availability using the mean time between failures (MTBF) and mean time to repair (MTTR) values.

Availability = MTBF / (MTBF + MTTR)

Availability = 37 hr / (37 hr + 0.92 hr)

Availability = 0.975 or 97.5%

Now we can calculate the total time that the machine is available for production:

Available time = Total time x Availability

Available time = 8.64 hr x 0.975

Available time = 8.42 hr

Average hourly production rate = Batch size / Available time

Average hourly production rate = 52 parts / 8.42 hr

Average hourly production rate = 6.17 parts/hr

Therefore, the average hourly production rate of the machine taking into account availability is 6.17 parts/hr.

(c) If availability only applies during the actual run time of the machine and not the setup time, we need to adjust the available time calculation:

Available time = (operation time per part x batch size) / 60 min/hr x Availability

Available time = (4.2 min/part x 52 parts) / 60 min/hr x 0.975

Available time = 4.11 hr

Total time = Available time + setup time

Total time = 4.11 hr + 5.0 hr

Total time = 9.11 hr

Average hourly production rate = Batch size / Total time

Average hourly production rate = 52 parts / 9.11 hr

Average hourly production rate = 5.71 parts/hr

Therefore, the average hourly production rate of the machine taking into account availability only during run time is 5.71 parts/hr.

Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

The mass of air in the tank is approximately 0.838 kg.

To find the mass of air in the tank, we first need to determine the density of the air at the given temperature and pressure.

The ideal gas law can be used for this calculation, which is:

PV = nRT

where:

P is the pressure (500 kPa or 500,000 Pa)

V is the volume (10 m³)

n is the number of moles of the gas

R is the specific gas constant for air (287 J/(kg·K))

T is the temperature (600 K)

First, we'll find the number of moles (n):

n = PV/RT

n = (500,000 Pa * 10 m³) / (287 J/(kg·K) * 600 K)

n = 5000000 / (287 * 600)

n ≈ 28.918 moles

Now, we'll convert moles to mass using the molar mass of air. The molar mass of dry air is approximately 28.97 g/mol or 0.02897 kg/mol:

mass (m) = n * molar mass

m = 28.918 moles * 0.02897 kg/mol

m ≈ 0.838 kg

So, the mass of air in the tank is approximately 0.838 kg.

48. None of the given options match the value.

49. None of the given options match the value.

50. The answer is approximately 3.16. Option c.

To solve the given questions, we can use the fin equation and the concept of effectiveness. Let's calculate the answers step by step:

46. The total heat transfer from the surface per meter length in the case of no fins can be calculated using the equation:

  Q = hAΔT

  Where:

  Q = Heat transfer rate

  h = Heat transfer coefficient

  A = Surface area

  ΔT = Temperature difference

  Q = 40 × (2πrL)

  ΔT = (180 - 25)

  Substituting the values:

  Q = 40 × (2 × 3.14 × 0.05 × 1)

  Q ≈ 100 W

  Therefore, the answer is approximately 100 W. None of the given options match this value.

47. The heat transfer from a single fin can be calculated using the equation:

  Q_fin = Q / (N × Efficiency)

  Where:

  Q_fin = Heat transfer from a single fin

  Q = Total heat transfer rate without fins

  N = Number of fins

  Efficiency = Fin efficiency

  Q_fin = 100 / ([(0.06 - 0.005) + 0.004] / 0.004)

  Q_fin ≈ 13.5 W

  Therefore, the answer is approximately 13.5 W. Option b matches this value.

48. The total heat transfer from the finned tube per meter length can be calculated using the equation:

  Q_total = Q_fin × N

  Where:

  Q_total = Total heat transfer rate with fins

  Q_fin = Heat transfer from a single fin

  N = Number of fins

  Q_total = 13.5 × [(0.05 - 0.006) / 0.004]

  Q_total ≈ 2295 W

  Therefore, the answer is approximately 2295 W. None of the given options match this value.

49. The increase in heat transfer from the tube per meter length can be calculated by subtracting the heat transfer rate without fins from the heat transfer rate with fins:

  Increase = Q_total - Q

  Increase = 2295 - 100

  Increase ≈ 2195 W

  Therefore, the answer is approximately 2195 W. None of the given options match this value.

50. The surface effectiveness for the finned surface can be calculated using the equation:

  Effectiveness = Q_total / (Q_fin × N)

  Effectiveness = 2295 / (13.5 × [(0.05 - 0.006) / 0.004])

  Effectiveness ≈ 3.16

  Therefore, the answer is approximately 3.16. Option c matches this value.

To summarize:

46. None of the given options match the value.

47. The answer is approximately 13.5 W. Option b.

48. None of the given options match the value.

b). 281.85 ohm

c). 10.2 ohm

Explanation:

Given :

Diameter, d = 22 m

Linear strain, \($\epsilon$\) = 3%

                        = 0.03

Young's modulus, E = 30 GPa

Gauge factor, k = 6.9

Gauge resistance, R = 340 Ω

a). Maximum truck weight

σ = Eε

σ = \($0.03 \times 30 \times 10^9$\)

\($\frac{P}{A} =0.03 \times 30 \times 10^9$\)

\($P = 0.03 \times 30 \times 10^9\times \frac{\pi}{4}\times (0.022)^2$\)

 = 342119.44 N

For the four sensors,

Maximum weight = 4 x P

                            =  4 x 342119.44

                            = 1368477.76 N

Therefore, weight in kg is \($m=\frac{W}{g}=\frac{1368477.76}{9.81}$\)

                     m = 139498.24 kg

b). Change in resistance

\(k=\frac{\Delta R/R}{\Delta L/L}\)

\($\Delta R = k. \epsilon R$\)    , since \($\epsilon= \Delta L/ L$\)

\($\Delta R = 6.9 \times 0.03 \times 340$\)

\($\Delta R = 70.38 $\) Ω

For 4 resistance of the sensors,

\($\Delta R = 70.38 \times 4 = 281.52$\) Ω

c). \($k=\frac{\Delta R/R}{\epsilon}$\)

If linear strain,

\($\frac{\Delta R}{R} \approx \frac{\Delta L}{L}$\)  , where k = 1

\($\Delta R = \frac{\Delta L}{L} \times R$\)

\($\Delta R = 0.03 \times 340$\)

When building a 3-dimensional object with linking cubes, it's important to consider each view and how the object would look from each side's projection.

The Top view would show the object from above, allowing you to see the shape and size of the object as a whole. The Front view would show the object from the front, giving you a clear idea of its height and width.

The Right view would show the object from the side, allowing you to see the depth and width.

The Isometric view is a 3-dimensional projection that shows the object in an angled view, giving you a sense of its depth, height, and width all at once. This is a useful view to see the overall shape and proportion of the object.

Therefore, When sketching each view, it's important to consider the line types used to represent the different parts of the object. For example, using different line types to represent hidden lines and visible lines can help to clearly show the 3-dimensional form of the object. The Sketching Reference resource provides information on different sketching line types that can be used.
