What are the coventional representative of automation

Answer:

They moved fresh water around their vast empire with aqueducts and canals.

Explanation:

An extremum is a point where the function has its highest or lowest value, and at which the slope is zero.

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum is as follows;

Reason:

The given parameters are;

Form of silo = Cylinder surmounted by a hemisphere

Cost of construction of hemisphere per square unit = 2 × The cost of of construction of the cylindrical side wall

Required:

The dimensions to be used if the volume is fixed and the cost of construction is to be kept to a minimum

Solution:

The fixed volume of the silo, V, can be expressed as follows;

\(V = \pi \cdot r^2 \cdot h + \dfrac{2}{3} \cdot \pi \cdot r^3\)

Where;

h = The height of the cylinder

r = The radius of the cylinder

The surface area is, Surface Area = 2·π·r·h + 2·π·r²

The cost, C = 2·π·r·h + 2×2·π·r² = 2·π·r·h + 4·π·r²

Therefore;

\(C = 2 \times \pi \times r\times \dfrac{V - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } + 4 \cdot \pi \cdot r^2 = \dfrac{8 \cdot r^3 \cdot \pi + 6 \cdot V}{3 \cdot r}\)

At the minimum value, we have;

Which gives;

16·π·r³ = 6·V

Which gives;

\(h = \dfrac{\dfrac{8 \cdot \pi \cdot r^3}{3} - \dfrac{2}{3} \cdot \pi \cdot r^3 }{\pi \cdot r^2 } = 2 \cdot r\)

h = 2·r

The height of the silo, h = 2 × The radius, 2

Therefore, the dimensions to be used if the volume is fixed and the cost is to be kept to a minimum is, height, h = 2 times the radius

Whenever bidding is done for seeking professional services, selection of contractor should be done using qualifications-based selection.

While seeking professional service, focus is on selecting the best quality and value matter, hence the contracting agency with best experience and skill for the job is selected.

In fully developed laminar flow in a pipe, the velocity profile is parabolic, meaning that the velocity is highest at the center of the pipe and decreases towards the walls.

The average velocity, also known as the mean velocity, is calculated by taking the integral of the velocity profile across the cross-section of the pipe and dividing it by the area of the cross-section.

Since the velocity profile is parabolic, the average velocity will be less than the velocity at the center of the pipe. This is because the velocity at the walls is zero, and the average velocity takes into account the lower velocities near the walls.

To summarize, in fully developed laminar flow, the average velocity is lower than the velocity at the center of the pipe due to the parabolic velocity profile.

Given the values of the barometer and atmospheric pressure on the ground and at the top of the building, its height is measured at 371.77 meters. The calculation steps are described below.

Entrance of a building = 99.4 kpa

Top of the building = 94.7 kpa

Gravity on earth = 9.80 m/s²

Air density = 1.29 kg/m3

Entrance of a building - Top of the building = 99.4 – 94.7 = 4.7

Building height = 4.7 kpa / (9.80 m/s² * 1.29 kg/m3)

Converting kilopascals (kpa) to newton/m2:

4.7 kpa = 4700 n/m2 (newton = (kg*m)/ s²)

Solving units of measurement for density and gravity:

m/s² * kg/m3 = kg/ (s² * m²)

Solving for units of newtons and meters:

n/m2 = ( (kg*m)/ s² ) / m² = (kg*m)/ ( s² * m² ) = kg/ ( s² * m )

After:

kg/ ( s² * m ) / ( kg/ ( s² * m²) ) = m

Finally;

Building height = 4700 / (9.8 * 1.29) m

Building height = 4700 / 12.64 m

Building height = 371.77 m

Explanation:

The continuity equation allows finding the results for the speed and flow of the outlet pipe are:

Fluid mechanics studies the movement and fluid dynamics, it is described  by two fundamental relationships:

          \(P_1 + \frac{1}{2} \rho v_1^2 + \rho g y_1 = P_2 + \frac{1}{2} \rho v_2^2 + \rho g y_2\)  

Where P is the pressure, v the velocity, y the height, the subscripts are two selected points of interest in the pipe.

            \(A_1v_1 = A_2 v_2\)

Where A₁ and A₂ is the area of ​​the inlet and outlet pipes and v₁ and v₂ are the velocities of the fluid at the inlet and outlet

They indicate the inlet and outlet diameters of the pipe are d₁ = 0.02 m and d₂ = 0.1 m, the inlet velocity v₁ = 10 m / s, with the continuity equation let's find the outlet velocity

         \(v_2 = ( \frac{A_1}{A_2} )^2 \ v_1\)  

the cross section of the tavern is

        A = \(\pi r^2 = \pi \ d^2/4\)  

Where r is the radius and d is the diameter

Let's substitutes

        \(v_2 = (\frac{d_1}{d_2} )^2 \ v_1\)  

        \(v_2 = (\frac{0.02}{0.1} )^2 \ 10\)  

        v₂ = 0.4 m / s

The flow  (Q) is defined as the amount of liquid that passes through the section of the pipe per unit of time, we can see that this is the same conservation of mass, therefore

        Q = A v

        Q = \(\pi \frac{d_2^2}{4} \ v_2\)π d2 ^ 2 v2

        Q = \(\pi \ \frac{0.1^2}{4} \ 0.4\)

        Q = 3.14 10⁻³ m ^ 3 / s

As the transported liquid is water

         1 liter water = 1 kg

Consequently

         1 m³ = 1000 liter = 1000 kg of water

Let's reduce the flow

         Q = 3.14 10⁻³ m³/s ( \(\frac{10^3 kg}{1 m^3}\) )

         Q = 3.14 kg / s

There are a few key benefits to a pre-construction and design specialist taking an interdisciplinary approach:

To maximize employability options. Having exposure to different fields and skills makes a specialist a more versatile and attractive job candidate. They can work across multiple areas of design, planning, architecture and construction.

To draw on a varied creative tool set. Exposure to fields like architecture, engineering, economics, sustainability and more provides many perspectives and solutions to tapping into. This leads to more innovative and well-rounded design thinking.

To integrate well with other team members. Understanding the methods, priorities, constraints and languages of fields like architecture, engineering, planning, and construction allows a specialist to collaborate more effectively. They can translate across disciplines and facilitate joined-up thinking.

To understand constraints and optimally balance priorities. No design or pre-construction problem has limitless options. An interdisciplinary approach helps gain insights into the constraints each field operates under and how to optimize solutions across ecological, economic, functional and other priorities.

To consider impacts holistically. Many impacts, like environmental sustainability, cost efficiency and user experience, span multiple disciplines. An interdisciplinary mindset is needed to evaluate options based on overall impact, not just impacts within one area of focus.

Of these options, I believe "To integrate well with other team members" is the strongest summary of why an interdisciplinary approach is so valuable for this type of specialist role. Understanding other fields in depth helps in collaborating, communicating clearly, addressing concerns proactively and finding optimal compromise - all of which are key to successfully interweaving different areas of expertise on a team.

The moment of inertia of one piece is 125 times smaller than the moment of inertia of original bar.

A body's resistance to having the speed of its rotation about an axis changed by the application of a torque is measured by the term "moment of inertia" in physics (turning force). The axis could be fixed or not fixed, internal or external.

Nevertheless, the moment of inertia (I), which is always specified in relation to that axis, is calculated as the sum of the products obtained by multiplying the mass of each particle of matter in a given body by the square of that particle's distance from the axis.

The moment of inertia can be compared to mass in linear momentum when calculating the angular momentum of a rigid body.
