Answer:

attached below

Explanation:

Given data:

Gaged flow = 52 m^3 / sec

Depth covering drainage area = 1450 km^2

Develop a 24-hour rainfall duration unit hydrograph for the watershed using observed hydorgraph

Runoff flow = gaged flow - base flows

                   = 52 - 52 = 0 m^3/sec

For 18 hours time duration

Direct runoff volume ( Vr ) = ∑ ( QΔt1 )

where Δt = 6

           ∑Q = 3666 m^3/sec

hence Vr = Δt * ∑Q  = 79185600 m^3

Next we will convert the Direct runoff volume to its equivalent depth covering the drainage area

= Vr / drainage area depth

= 79185600 / 1450000000 = 5.46 cm

Next we will find the unit hydrograph flows by applying the relation below

\(Q_{1.0cm} = Q_{5.46cm} (\frac{1.0cm}{5.46cm} )\)

where 14m^3/sec = \(Q_{5.6cm}\)

input value back to the above relation

\(Q_{1.0cm} = 2.57 m^3/sec\)

The statement "For the typical design of a municipal piping system, both the prandtl and reynolds numbers are usually very critical." is false.

This is False.

While both Prandtl and Reynolds numbers are important parameters in fluid mechanics, the criticality of their values in municipal piping system design varies depending on the application.

The Prandtl number represents the ratio of momentum diffusivity to thermal diffusivity. It is used to determine the thermal boundary layer thickness and heat transfer characteristics in fluids. In municipal piping systems, the Prandtl number may not be as critical as other parameters such as flow rate and pressure drop.

The Reynolds number, on the other hand, represents the ratio of inertial forces to viscous forces. It is used to predict the onset of turbulent flow and to determine pressure drop and pumping requirements. In municipal piping systems, the Reynolds number is an important parameter in designing for optimal flow rates and minimizing energy consumption.

In conclusion, while both Prandtl and Reynolds numbers are important in fluid mechanics, their criticality depends on the specific application and design requirements of municipal piping systems.

the torque is required to rotate the inner cylinder at 12 r min, the outer cylinder remaining stationary is 11.0807 N-m.

we have left out some other important details, such as the time required to reach that rpm, whether the beginning state is at rest, and the axis around which the cylinder is revolving. However, we'll suppose that it will be 60 seconds (time is necessary to convert rpm to angular acceleration)

rotation around the center axis

Angular acceleration = torque + MOI

Currently, angular acceleration equals 2 rpm/(t 60).

In order to avoid getting an extremely high figure, we estimated that the diameter of the cylinder was 600 mm rather than 600 meters: angular acceleration= 1.047 rad/s² MOI for cylinder across center dia= 1/4MR²+ 1/12ML²

Answer:

Explanation:

Given data

steel tube : outer diameter = 50-mm

power transmitted = 100 KW

frequency(f) = 34 Hz

shearing stress ≤ 60 MPa

Determine tube thickness

firstly we calculate the ; power, angular velocity and torque of the tube

power = T(torque) * w (angular velocity)

angular velocity ( w ) = 2\(\pi\)f = 2 * \(\pi\) * 34 = 213.71

Torque (T) = power / angular velocity = 100000 / 213.71 = 467.92 N.m/s

next we calculate the inner diameter  using the relation

  \(\frac{J}{c_{2} } = \frac{T}{t_{max} }\)  = 467.92 / (60 * 10^6) =  7.8 * 10^-6 m^3

also

c2 = (50/2) = 25 mm

\(\frac{J}{c_{2} }\) = \(\frac{\pi }{2c_{2} } ( c^{4} _{2} - c^{4} _{1} )\) =  \(\frac{\pi }{0.050} [ ( 0.025^{4} - c^{4} _{1} ) ]\)

therefore; 0.025^4 - \(c^{4} _{1}\) = 0.050 / \(\pi\) (7.8 *10^-6)

\(c^{4} _{1}\) = 39.06 * 10 ^-8 - ( 1.59*10^-2 * 7.8*10^-6)

    39.06 * 10^-8 - 12.402 * 10^-8 =26.66 *10^-8

\(c_{1} = \sqrt[4]{26.66 * 10^{-8} }\)  =

The required diameter (d) for the solid shaft is approximately 48.97 mm.

To determine the required diameter (d) of a solid shaft that can carry the same torque and have the same maximum shear stress as a tube with an outer diameter (D) of 60 mm and a thickness of 15 mm, we need to consider the torque and shear stress equations for solid and hollow circular sections.

For a solid circular shaft, the torque (T) can be calculated using the equation:

T = (π/16) * τ_max * d^3

where τ_max is the maximum shear stress.

For a hollow circular tube, the torque (T) can be calculated using the equation:

T = (π/16) * τ_max * (D^4 - d^4) / D

In this case, we want to find the diameter (d) of the solid shaft that can carry the same torque and have the same maximum shear stress as the given hollow tube with an outer diameter (D) of 60 mm and a thickness of 15 mm.

By equating the torque equations for the solid shaft and the hollow tube, we have:

(π/16) * τ_max * d^3 = (π/16) * τ_max * (D^4 - d^4) / D

We can simplify the equation by canceling out common terms:

d^3 = (D^4 - d^4) / D

Next, we can rearrange the equation:

D * d^3 = D^4 - d^4

Substituting the values for D and rearranging further, we get:

D * d^3 + d^4 = D^4

d^3 = D^4 - (D - 2t)^4

d^3 = (60 mm)^4 - (60 mm - 2 * 15 mm)^4

d^3 = 129,600,000 mm^4 - 20,736,000 mm^4

d^3 = 108,864,000 mm^4

Take the cube root of both sides to solve for d:

d = ∛(108,864,000 mm^4)

d ≈ 48.97 mm

Now, we can solve this equation for the required diameter (d) of the solid shaft. By iterating through different values of d and comparing the left and right sides of the equation, we can find the value of d that satisfies the equation and gives the required diameter for the solid shaft.

Therefore, the design factor is 7.2 and the maximum allowable load that will offset the absolute uncertainties is 14400 lbs.

To determine the design factor and the maximum allowable load, we need to consider the uncertainties given.
The maximum load on a structure is known with an uncertainty of 620 percent, which means the actual maximum load could be 620 percent higher or lower than the nominal value. Similarly, the load causing failure is known within 615 percent, so the actual load causing failure could be 615 percent higher or lower than the nominal value of 2000 lbf.

To account for these uncertainties, we can calculate the design factor and maximum allowable load.

Design factor = (Actual maximum load) / (Nominal load causing failure)

Actual maximum load = Nominal load causing failure + (Nominal load causing failure * uncertainty on maximum load)

Actual maximum load = 2000 lbf + (2000 lbf * 620%)

Maximum allowable load = (Design factor) * (Nominal load causing failure)

Substituting the values:

Actual maximum load = 2000 lbf + (2000 lbf * 620%)
Actual maximum load = 2000 lbf + (2000 lbf * 6.2)
Actual maximum load = 2000 lbf + 12400 lbf
Actual maximum load = 14400 lbf

Design factor = 14400 lbf / 2000 lbf
Design factor = 7.2

Maximum allowable load = 7.2 * 2000 lbf
Maximum allowable load = 14400 lbf

In a balanced three-phase system, the conductors need to be only about the size of conductors for a single phase, two-wire system of the same kilovolt-ampere (KVA) rating by 75%.

In a balanced three-phase system, the power is distributed equally among the three phases, resulting in a more efficient use of conductors compared to a single-phase system. This allows for a reduction in conductor size while maintaining the same kilovolt-ampere rating.

The conductors in a three-phase system carry a lower current compared to a single-phase system for the same power transfer, which reduces the resistive losses and allows for smaller conductors. The approximate 75% reduction in conductor size is a general rule of thumb in balanced three-phase systems.

In a three-phase system, the power delivered is constant, and the conductors carry only the unbalanced current. As a result, each conductor in a balanced three-phase system carries approximately 1/sqrt(3) or 57.7% of the total current, which allows for a 75% reduction in conductor size compared to a single-phase, two-wire system of the same KVA rating. This results in cost savings and improved efficiency.

Building a recommender system for a large online shop with over 100,000 items can be a daunting task. The behavior of customers is crucial in this domain and can be captured by what items they have bought or not bought. In this scenario, the company has decided to use a similarity-based model to implement the recommender system.

A similarity-based model recommends items to customers based on the similarities between their behavior and that of other customers. This is done by calculating the similarity index between two customers. There are three similarity indexes that can be used in this scenario: Cosine similarity, Pearson correlation, and Jaccard similarity.

Cosine similarity is a measure of the cosine of the angle between two vectors. It is widely used in recommendation systems because it is efficient and effective. Cosine similarity ranges from -1 to 1, with 1 indicating perfect similarity and -1 indicating complete dissimilarity.

Pearson correlation is a measure of the linear correlation between two variables. It is commonly used in recommendation systems when the data is normally distributed. Pearson correlation ranges from -1 to 1, with 1 indicating perfect correlation and -1 indicating perfect negative correlation.

Jaccard similarity is a measure of the similarity between two sets. It is used when the data is binary, that is, when the customer has either bought the item or not. Jaccard similarity ranges from 0 to 1, with 1 indicating perfect similarity.

In conclusion, the choice of similarity index depends on the type of data available and the distribution of the data. In this scenario, since the behavior of customers is captured in terms of what items they have bought or not bought, Jaccard similarity would be the most appropriate index to use. However, if the data was normally distributed, Pearson correlation would be a better choice. Finally, if the data was sparse and high-dimensional, Cosine similarity would be the best choice.

The fundamental difference between effective and less effective matrix organizations is whether the tension between different perspectives is creative or destructive. While various processes, systems and tools can help, what matters most is what top leadership says and does and how that flows through the organization in shared targets, clear accountabilities, live team interactions and team-building transparency and behaviors.

Getting matrix management right is linked inextricably to an organization’s culture - the only sustainable competitive advantage. Key components of a culture can be grouped into behaviors, relationships, attitudes, values and the environment.

Environment and values: Each organization has its own environment, context and bedrock values. Everyone needs to know what matters and why. Don’t try to do anything else until you’ve got that set.

Attitude is about choices: An organization’s overall strategy drives choices about which of its parts will be best in class (superior), world class (parity), strong (above average), or simplified/outsourced to be good enough. These choices help determine the need for a matrix and how best to design it.

Relationships and behaviors: This is why organizations have matrices. The most effective of them best balance focus and collaboration. They allow leaders and teams to build differential strengths and then work together to make the best possible decisions and scale enterprises with a creative tension that they could not do on their own.
