True or False? a routing table tracks the state and context of each packet in a conversation by recording which station sent which packet and when.

Answer: Tl = - 13.3°C

the lowest outdoor temperature is - 13.3°C

Explanation:

Given that;

Temperature of Th = 21°C = 21 + 273 = 294 K

the rate at which heat lost is Qh = 5400 kJ/h°C

the power input to heat pump Wnet = 6 kw

The COP of a reversible heat pump depends on the temperature limits in the cycle only, and is determined by;

COPhp = Th/(Th - Tl)

COPhp = Qh/Wnet

Qh/Wnet = Th/(Th -Tl)

the amount of heat loss is expressed as

Qh = 5400/3600(294 - Tl)

the temperature of sink

( 5400/3600(294 - Tl)) / 6 = 294 / ( 294 - Tl)

now solving the equation

Tl = 259.7 - 273

Tl = - 13.3°C

so the lowest outdoor temperature is - 13.3°C

Aspiring for success in a chosen major such as Mechanical Engineering would require a strong will or zeal to pull through and succeed, which is an ideal psychological prerequisite to success.

Answer:

The Meter bridge is the modification of Wheatstone's network used to determine the value of unknown resistance. The meter bridge consists of a thin, uniform, and homogenous conducting wire AC, rectangular wooden board between two thick L shaped metal strips C1 and C2 as shown in the diagram.

The allowable normal strength in the c-section is 48000 pounds per square inch.

The allowable stress depends on both the factor of safety imposed on the object and the yield strength or stress at which an object will be permanently damaged. To calculate the allowable normal strength we can divide the yield strength by the factor of safety.

To determine the allowable normal strength output we can use this equation below:

The allowable normal strength = The number yield strength : A stress-concentration factor

The number yield strength is 84 kpsi.

Then convert kpsi to psi : 84 kpsi = 84000 psi

A stress-concentration factor is 1.75

The formula to find allowable normal strength output is:

84000 psi : 1.75 = 48000

Answer:

11.87 ft

Explanation:

Volumetric flow rate of the turbine Q = 1.7 million gal/min

Q = 1.7 x \(10^{6}\) gal/min

1 gal = 0.00378541 m^3

1 min = 60 sec

1.7 x \(10^{6}\) gal/min = (1.7 x \(10^{6}\) x 0.00378541)/60 = 107.25 m^3

average velocity of flow through turbine = 34 ft/s

1 ft = 0.3048 m

34 ft/s = 34 x 0.3048 = 10.36 m/s

According to continuity equation, Q = AV

where Q = volumetric flow rate

A = Area of conduit

V = velocity of flow through turbine

A = Q/V = 107.25/10.36 = 10.35 m^2

Area of conduit = \(\pi r ^{2}\)

radius r = \(\sqrt{\frac{area}{\pi } }\) = \(\sqrt{\frac{10.35}{3.142} }\) = 1.81 m

diameter = 2 x radius = 2 x 1.81 = 3.62 m

diameter = 3.62 m = 3.62 x 3.28084 = 11.87 ft

As there is no internal fluid pressure acting on the pipe, the maximum hoop stress across the segment of the pipe is therefore zero.

The formula below can be used to determine the maximum hoop stress (h) along the pipe section:

σh = (p x d) / (2 x t) (2 x t)

The pipe in this instance has an external diameter (d) of 600 mm and an internal diameter of 440 mm. The following formula can be used to determine the pipe wall's thickness (t):

t = (d – D) / 2 t = (600 – 440) / 2 t = 80 mm

When the values are added to the formula, we obtain:

h = (600 mm x 0 N/mm2) / (2 x 80 mm)

σh = 0 N/mm²

As there is no internal fluid pressure acting on the pipe, the maximum hoop stress across the segment of the pipe is therefore zero.

Answer:

A

Explanation:

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

(a) The free rotational motion of an axially symmetric rigid body with Ia = 2It, where Ia is the axial moment of inertia and It is the transverse moment of inertia. We are to find the largest possible value of the angle between ω and H. The hint is that we should consider the angular momentum magnitude ∣H∣ fixed and vary the kinetic energy T.

The angular momentum H is given by:H = IωsinθWhere I = It + Ia, ω is the angular velocity, and θ is the angle between the vectors H and ω. So the angular momentum magnitude ∣H∣ is given by:|H| = IωsinθBut we are to consider ∣H∣ to be fixed. So Iωsinθ is constant. Therefore, the product Iω should be constant as well. Thus, we have:Iω = constantThis is known as the conservation of angular momentum.

The kinetic energy T is given by:T = (1/2)Iaω² + (1/2)Itω²= (1/2)(Ia + It)ω²= (3/4)Itω²(Using Ia = 2It)The kinetic energy T is proportional to ω². So as T varies, ω varies as well. However, Iω is constant. As T increases, ω increases, and as T decreases, ω decreases. Since ∣H∣ = Iωsinθ is constant, the angle θ between ω and H varies with T. So we have sinθ varying with T. The angle θ will be largest when sinθ is largest.

Thus, sinθ should be maximized. The largest value that sinθ can take is 1. So θ is maximized when sinθ = 1 or θ = 90°. Therefore, the largest possible value of the angle between ω and H is 90°. The angular momentum vector H and the angular velocity vector ω are perpendicular to each other.

(b) We are to find the critical value of kinetic energy that results in the largest angle between ω and H. We know that the kinetic energy T is given by:T = (3/4)Itω² (Using Ia = 2It)Now, we are to find the maximum value of T. We know that T is proportional to ω². Thus, we can find the maximum value of T by maximizing ω². But Iω is constant. So we have:Iω = constant=> ω = constant/IThe kinetic energy T is given by:T = (3/4)Itω²= (3/4)It(constant/I)²= (3/4)(It/I²)constant²= (3/4)(It/Ia)constant²(Using Ia = 2It), The critical value of kinetic energy that results in the largest angle between ω and H is (3/4)(It/Ia)constant².

The viscosity of the liquid in this case is 0.162 Pa s.

The Concentric Cylinder Viscometer is used to calculate the viscosity of fluids.

The device is composed of a fixed outer cylinder and a rotating inner cylinder, which are divided by a small gap filled with the liquid whose viscosity is being measured.

Assume that the liquid has a linear velocity distribution.

The viscosity of the liquid can be determined using the following formula:

τ = μ d γ/dy

where

τ is the torque required to rotate the inner cylinder at a given rate

μ is the viscosity of the liquid

d is the distance between the two cylinders

y is the height of the liquid layer

In this case, the given value of torque is 0.021 N-m.

The diameter and height of the inner cylinder are 75 mm and 150 mm, respectively.

The gap between the cylinders is 0.02 mm.

For the given liquid, the torque is:

τ = 0.021 N-m

The inner cylinder diameter is:

d = 75 mm

Therefore, the radius of the inner cylinder is:

r = d/2 = 37.5 mm

The height of the liquid layer is:

y = 150 mm

The gap between the cylinders is:δ = 0.02 mm

The angular velocity is:

ω = 100 rpm

= (100/60) × 2π rad/s

= 10.472 rad/s

The shear rate is:

γ = ω r/δ

= 10.472 × 0.0375/0.02

= 19.46 s-1

Using the equation above, we can calculate the viscosity of the liquid:

τ = μ d γ/dyμ

= τ dy/dγ

= (0.021 N-m) (0.15 m)/(19.46 s-1)

= 0.000162 N s m-2

= 0.162 Pa s

Therefore, the viscosity of the liquid in this case is 0.162 Pa s.

Answer:

A GCU (Generator Control Unit) typically switches the starter to gen mode once the generator has reached the correct speed and voltage to generate electricity. This is usually monitored by sensors that detect the speed and voltage of the generator, and once these parameters reach the required levels, the GCU will automatically switch the starter to gen mode.

The exact timing of the switch from starter to gen mode can vary depending on the specific design and configuration of the generator system, as well as the specific application and load requirements. However, in general, the switch from starter to gen mode is typically made as soon as possible after the generator has reached the required speed and voltage to ensure that the generator is producing power efficiently and reliably.

The vectors are magnitude of vector v is 5. The sum of vectors v1 and v2 is (+) = (2, 1, 8).  The difference between vectors v1 and v2 is (-) = (6, -1, -2). The scalar multiple of vector v1 by 3 is 3(2, 0, 3) = (12, 0, 9).

To find the magnitude (||) of a vector, we can use the formula:

||v|| = sqrt(v1^2 + v2^2 + v3^2)

Given vector v = (4, 0, 3), we can calculate its magnitude as follows:

||v|| = sqrt(4^2 + 0^2 + 3^2)

     = sqrt(16 + 0 + 9)

     = sqrt(25)

     = 5

Therefore, the magnitude of vector v is 5.

Now, let's find the sum (+) and difference (-) of the given vectors.

Given vectors v1 = (4, 0, 3) and v2 = (-2, 1, 5), the sum of these vectors is calculated by adding the corresponding components:

v1 + v2 = (4 + (-2), 0 + 1, 3 + 5)

       = (2, 1, 8)

The difference between the vectors is found by subtracting the corresponding components:

v1 - v2 = (4 - (-2), 0 - 1, 3 - 5)

       = (6, -1, -2)

Lastly, let's calculate the scalar multiple of vector v1:

3v1 = 3(4, 0, 3)

   = (12, 0, 9)

Therefore, the vectors are as follows:

- The magnitude of vector v is 5.

- The sum of vectors v1 and v2 is (+) = (2, 1, 8).

- The difference between vectors v1 and v2 is (-) = (6, -1, -2).

- The scalar multiple of vector v1 by 3 is 3(2, 0, 3) = (12, 0, 9).

The displacement and rotation at point A can be determined using the double integration method.

The double integration method is a mathematical technique used to calculate displacement and rotation of a structure or body based on acceleration data. It involves two stages of integration: first, integrating the acceleration function twice to obtain the displacement function, and second, integrating the acceleration function once to obtain the rotation function.

To apply the double integration method, you need to have the acceleration data as a function of time. Let's assume you have the acceleration function a(t).

To find the displacement function, you perform two integrations of the acceleration function with respect to time. The first integration gives you the velocity function v(t), and the second integration yields the displacement function **x(t)**. Mathematically, the displacement function can be represented as:

**x(t) = ∫[∫a(t)dt]dt**

Similarly, to find the rotation function, you perform one integration of the acceleration function with respect to time. The result is the angular velocity function ω(t), and another integration gives you the rotation function **θ(t)**. Mathematically, the rotation function can be represented as:

**θ(t) = ∫a(t)dt**

Once you have obtained the displacement function **x(t)** and the rotation function **θ(t)**, you can evaluate them at point A to determine the displacement and rotation at that specific location.

It's important to note that the double integration method assumes constant accelerations between the data points. If the accelerations vary significantly, additional techniques such as numerical integration or finite element analysis may be required for more accurate results.

Critical load Fcr or buckling load is the value of load that causes the phenomenon of change from stable to unstable equilibrium state.

With that beign said, first it is neessary to calculate the moment of inercia about the x-axis:

\(Ix= \frac{db^3}{12}\\ Ix = \frac{2.(4)^3}{12} = 10.667in\)

Then it is necessary to calculate the moment of inercia about the y-axis:

\(Iy = \frac{db^3}{12}\\ Iy = \frac{4.(2)^3}{12} = 2.662in\)

Comparing both moments of inercia it is possible to assume that the minimun moment of inercia is the y-axis, so the minimun moment of inercia is 2662in.

And so, it is possible to calculate the critical load:
