ANSWER : all of the above

Explanation:

Laminar flow  is the flow of a type of fluid across the surface of an object following regular paths and it is unlike a turbulent flow which flows in irregular paths (encountering fluctuations)

For laminar flow over a hot flat plate, the local heat transfer coefficient decreases with distance because :

The overall transfer function for the two systems in series is 2/ s²(2s + 1)(3s + 1).

It should be noted that to develop the transfer function for the two systems in series, we need to first express them in terms of transfer functions:

For the first system:

2dy/dt + y = 1

2sY(s) + Y(s) = 1/s

Y(s)(2s + 1) = 1/s

Y(s) = 1/s(2s + 1)

For the second system:

3dy/dt + y = 2

3sY(s) + Y(s) = 2/s

Y(s)(3s + 1) = 2/s

Y(s) = 2/s(3s + 1)

The overall transfer function for the two systems in series is obtained by multiplying their individual transfer functions, since the output of the first system is the input to the second system.

Hence, the overall transfer function is given by:

G(s) = Y(s)/X(s) = (1/s(2s + 1)) * (2/s(3s + 1))

G(s) = 2/ s²(2s + 1)(3s + 1)

In a channel where a modem transmits a +2 voltage signal, the PMF of the output Y includes probabilities of 4/10 for +2, 3/10 for +1, 2/10 for 0, and 1/10 for -1. The probability of the output being equal to the input is 4/10, and the probability of the output being positive is 7/10.

To solve this problem, we'll use the given probabilities to determine the probability mass function (PMF) of the output Y of the channel.

(a) PMF of the output Y:

Let's define Y as the output of the channel after adding noise. The possible values of Y are determined by adding the noise terms to the input signal.

Y = +2 + 0 = +2 (with probability 4/10)

Y = +2 + (-1) = +1 (with probability 3/10)

Y = +2 + (-2) = 0 (with probability 2/10)

Y = +2 + (-3) = -1 (with probability 1/10)

Therefore, the PMF of Y is:

P(Y = +2) = 4/10

P(Y = +1) = 3/10

P(Y = 0) = 2/10

P(Y = -1) = 1/10

(b) Probability that the output is equal to the input:

We can see from the PMF that Y = +2 occurs with a probability of 4/10. Therefore, the probability that the output of the channel is equal to the input is 4/10.

(c) Probability that the output is positive:

The values of Y that are positive are +2 and +1. From the PMF, we can calculate the probability as follows:

P(Y > 0) = P(Y = +2) + P(Y = +1) = (4/10) + (3/10) = 7/10

Therefore, the probability that the output of the channel is positive is 7/10.

Answer:

To calculate the coolant boiling point with a 15 psi pressure cap, we need to consider the base boiling point of water, the increase in boiling point due to the 50-50 mix of coolant, and the increase in boiling point per psi of pressure.

Base Boiling Point of Water: 100°C

Increase in Boiling Point due to Coolant Mix: 6°C

Increase in Boiling Point per psi: 17°C

Calculation for a 15 psi pressure cap:

Base Boiling Point + Increase due to Coolant + (Pressure Increase × Increase per psi)

= 100°C + 6°C + (15 psi × 17°C/psi)

= 100°C + 6°C + 255°C

= 361°C

Therefore, with a 15 psi pressure cap, the cooling system boiling point would be 361°C.

Now let's calculate the boiling point with a 12 psi pressure cap:

Base Boiling Point + Increase due to Coolant + (Pressure Increase × Increase per psi)

= 100°C + 6°C + (12 psi × 17°C/psi)

= 100°C + 6°C + 204°C

= 310°C

With a 12 psi pressure cap, the cooling system boiling point would be 310°C.

If pure water is used instead of a 50-50 mix of coolant, the boiling point would remain at 100°C since there would be no additional increase in boiling point due to the coolant mix.

As for the freezing point, the presence of the coolant mix or the pressure cap does not directly affect the freezing point of water. The freezing point of water is generally 0°C, regardless of the coolant mix or pressure conditions.

The conservation of linear and angular momentum, we can calculate the maximum angle of rotation (θ) before the system comes to temporary rest. The calculated maximum angle in this case is 0.86 rad.

Now, apply the conservation of linear momentum, Initial momentum = Final momentum (as the total momentum is conserved)Initially the system was at rest.

Therefore, the initial momentum of the system is zero.

The final momentum of the system can be calculated as follows.

Consider the mass of the rod is negligible.mA + mB + mc is the mass of the system before the collision and the velocity of particle C is vc.

Therefore, the final momentum of the system is (mA + mB + mc)vc.

Next, apply the conservation of angular momentum.

Considering point O as the point of rotation, the initial angular momentum is zero as all the particles are at rest. The final angular momentum of the system can be calculated as follows.

θ is the angle of rotation and I is the moment of inertia of the system.

The moment of inertia can be calculated as follows. I = I rod + I A + I B Where,

Substitute the values of M, L and loB in the above expressions to find the moment of inertia. Now, substitute all the values in the final angular momentum expression to get the final angular momentum.

Now, equate the initial angular momentum and final angular momentum. Solve the equation for θ to find the angle of rotation achieved before coming to rest.

Therefore, the maximum angle to which the system rotates before achieving temporary rest is 0.86 rad.

The relationship between density, pipe average velocity, and cross-sectional area perpendicular to the velocity can be used to calculate mass flow rate.

The quantity of mass flowing across a cross-section per unit of time is known as the mass flow rate. The volume of the fluid moving through a cross-section per unit time is referred to as a volume flow rate. By multiplying the fluid's density, the average pipe velocity, and the cross-sectional area of the pipe normal to the velocity, one can compute the mass flow rate, which is a measurement of the amount of mass flowing through a particular cross-section per unit time. Contrarily, volume flow rate is defined as the amount of fluid moving across a specific cross-section in a unit of time. The mass flow rate into a control volume is proportional to the velocity component parallel to the cross-sectional area for fluid flow in a pipe, when the velocity is constant across the pipe's cross-section.

To prove the relationship between the mean coefficient of friction (μ) and the shear angle (x), given that the frictional force (F) on the tool rake face is equal to KtA, where K is a constant, A is the area of the cross-section of the chip, and a is the rake angle, we can follow these steps:

Step 1: Express the frictional force in terms of the mean coefficient of friction:

The frictional force, F, is equal to the product of the mean coefficient of friction (μ) and the normal force (N), which is equal to KtA:

F = μN = μKtA.

Step 2: Calculate the normal force, N:

The normal force can be determined using trigonometry. Since a is the rake angle, the component of the normal force in the direction of the shear force is N cos(x - a).

Step 3: Equate the frictional force with the calculated normal force:

Setting F = N cos(x - a), we get:

μKtA = N cos(x - a).

Step 4: Substitute the expression for the normal force:

μKtA = (N cos(x - a)).

Step 5: Rearrange the equation to solve for μ:

Divide both sides by N cos(x - a):

μ = KtA / (N cos(x - a)).

Step 6: Express N in terms of K and A:

Using trigonometry, we find that N = K sin(x - a).

Step 7: Substitute N into the equation:

μ = KtA / ((K sin(x - a)) cos(x - a)).

Step 8: Simplify the expression:

μ = K cos^2(x - a) / (K sin(x - a) cos(x - a) + 1).

Therefore, we have derived the relationship between the mean coefficient of friction (μ) and the shear angle (x) as μ = K cos^2(x - a) / (K sin(x - a) cos(x - a) + 1), where K is a constant, A is the area of the cross-section of the chip, and a is the rake angle.

In point b, Calculating the wetter perimeter.

\(\bold{P_w =B+2\times D_f}\)

      \(= 6 +2\times (5)\\\\= 6 +10 \\\\=16 \ ft\)

In point c, Calculating the hydraulic radius:

\(\bold{R=\frac{A}{P_w}}\)

   \(=\frac{30}{16}\\\\= 1.875 \ ft\)

In point d, Calculating the value of Reynolds's number.

\(\bold{Re =\frac{4VR}{v}}\)

     \(=\frac{4V \times 1.875}{1 \times 10^{-5} \frac{ft^2}{s}}\\\\\)

     \(=750,000 V\)

Calculating the velocity:

\(V= \sqrt{\frac{8gRS}{f}}\)

   \(= \sqrt{\frac{8\times 32.2 \times 1.875 \times 0.02}{f}}\\\\=\frac{3.108}{\sqrt{f}}\\\\\)

\(\sqrt{f}=\frac{3.108}{V}\\\\\)

calculating the Cole-brook-White value:

\(\frac{1}{\sqrt{f}}= -2 \log (\frac{K}{12 R} +\frac{2.51}{R_e \sqrt{f}})\\\\ \frac{1}{\frac{3.108}{V}}= -2 \log (\frac{2 \times 10^{-2}}{12 \times 1.875} +\frac{2.51}{750,000V\sqrt{f}})\\\)

\(\frac{V}{3.108} =-2\log(8.88 \times 10^{-5} + \frac{3.346 \times 10^{-6}}{750,000(3.108)})\)
