The voltage that will result in fracture with an internal flaw of size 10 microns is approximately 245.66 MPa.

To calculate the stress that will result in fracture with an internal flaw of size 10 microns, we can use the Griffith's theory of brittle fracture. The formula for Griffith's theory is:

σ = \(\sqrt{ (2 * E * s / \pi * a)}\)

Where σ is the stress, E is the Young's modulus, γs is the surface energy, and a is the flaw size.

Given in the question:
a = 10 microns = \(10 * 10^(^-^6^)\) meters
γs = \(0.3 J/m^2\)
E = \(69 GPa = 69 * 10^9 Pa\)

Now, we can plug these values into the formula:

σ = \(\sqrt{ (2 * (69 * 10^9) * 0.3 / (\pi * (10 * 10^(^-^6^)))}\)
σ ≈ \(245.66 MPa\)

Therefore, the voltage that will result in fracture with an internal flaw of size 10 microns is approximately 245.66 MPa.

The sections of piping immediately upstream and downstream of a primary flow measuring device are known as the "straight run."

The straight run refers to the lengths of piping that are required to be present immediately upstream and downstream of a primary flow measuring device. These sections of piping are necessary to ensure that the flow profile is fully developed and unaffected by any disturbances caused by bends, fittings, or obstructions in the pipe. The straight run allows the fluid to flow smoothly and uniformly before entering or exiting the flow measuring device, ensuring accurate and reliable measurements.

By providing sufficient straight run lengths, the flow profile becomes stable, minimizing turbulence and disturbances that could impact the accuracy of the flow measurement.

Centrifugal force is the force exerted on an object moving in a circular path and directed outward from the center. In order to determine the centrifugal force in pound-force of a centrifuge carrying 50mL of blood, we will need to use the formula for centripetal force:

Centrifugal force = (mass x acceleration)/radius

Here's how to solve the problem:

First, we need to determine the mass of the blood being carried by the centrifuge. We know the volume of blood (50 mL) and the density of blood (0.994 g/mL), so we can use the formula:

mass = volume x density

mass = 50 mL x 0.994 g/mL

mass = 49.7 g

Next, we need to convert the given units to SI units (meters and seconds):

Centripetal acceleration = 64 ft/s^2
1 ft = 0.3048 m
Centripetal acceleration = 64 ft/s^2 x 0.3048 m/ft = 19.5072 m/s^2

Rotational speed = 345 rpm
1 rpm = 1/60 s
Rotational speed = 345 rpm x 1/60 s = 5.75 s^-1

Now we can use the formula to calculate centrifugal force:

Centrifugal force = (mass x acceleration)/radius

The radius of the centrifuge is half the diameter (3.5 inches or 0.0889 meters):

Centrifugal force = (49.7 g x 19.5072 m/s^2)/0.0889 m

Centrifugal force = 10,879.52 N

Finally, we need to convert Newtons to pound-force:

1 N = 0.22481 lb-f
Centrifugal force = 10,879.52 N x 0.22481 lb-f/N

Centrifugal force = 2,442.69 lb-f

Therefore, the centrifugal force in pound-force is 2,442.69 lb-f.

Answer:

t = 0.4 s

Explanation:

Here, we will use Ohm's Law to find out the value of time at which the current in resistive element becomes 1 A. Therefore,

V = IR

V(t)/R = I

where,

V(t) = Voltage in terms of time = 100 Sin (100t - 10)

R = Resistance of the element = 50 Ω

I = Current = 1 A

Therefore,

100 Sin (100t - 10)/50 Ω = 1 A

Sin (100t - 10) = 1/2

100t - 10 = Sin⁻¹(1/2)

100t = 10 + 30

t = 40/100

(a) The height of the cliff is 80.5 m

(b) The final velocity of the stone before it strikes A is 26.22 m/s

(c) The maximum height reached by the stone is 88.67 m

Velocity may be defined as the rate at which an object moves in a certain direction. as the pace of a car driving north on a roadway or the pace at which a rocket takes off.

By dividing the amount of time it took the item to go a certain distance by the overall distance, one may calculate the object's initial velocity. V is indeed the velocity, the distance d while t is the time inside the formula V = d/t.

(a) Using the same coordinate system assumed in Eq. , we solve for y=h:

h=y₀+v₀sinθ₀t−1/2gt²

which yields h=80.5m for y₀=0, v₀=46.0m/s, θ₀=65.0°, and t=5.54s.

(b) The horizontal motion is steady, sovₓ =v₀ₓ =v₀cosθ₀ but the vertical component of velocity varies according to Eq. . Thus, the speed at impact is

v=√(v₀ cos₀)²+(v₀ sinθ₀− gt)²=26.22m/s

On solving for A and B, we get A= (7 - 5j)/20 and B= (7 + 5j)/20

we get \(Y(s) as Y(s) = [(7 - 5j)/20]/(s+3 - j4) + [(7 + 5j)/20]/(s+3 + j4)... (5\))

Hence, using the convolution property of Laplace transforms, we get the output response as follows:

y(t) = L^(-1){ Y(s)}... (2)

Y(s) = H(s) X(s)Y(s)

\(= (5s+2)/(s^2 + 4s+ 13) . L{ e^(-3t)cos(2t)Y(s) = (5s+2)/(s^2 + 4s+ 13) . [ s + 3] / [(s+3)^2 + 4^2]...\)

The inverse Laplace transform of Y(s) gives the required response y(t). For the calculation of Y(s) we need to split Y(s) into partial fractions. For that, we need to factorize the denominator first.

The answer is analyze

Answer:

the rate at which heat is added in the boiler = 59597.4 kW

the power required to operate the pumps = 122.57 kW

The net power produced by the cycle = 17925 kW.

The thermal efficiency = 30%.

Explanation:

The specific enthalpy of saturated liquid is equal to the enthalpy of the first point which is equal to 314 kJ/ kg.

The second enthalpy is calculated from the pump work. Therefore, the second enthalpy = first enthalpy point + specific volume of water [ the pressure of the boiler - the pressure of the condenser].

The second enthalpy = 314  + 0.00103 [ 6000 - 50 ] = 320.13 kJ/kg.

The specific enthalpy for the third point = 3300 kJ/kg.

Therefore, the rate at which heat is added in the boiler = 20 × [3300 - 320.13] = 59597.4 kW.

The rate at which heat is added in the boiler = 59597.4 kW.

Also, the power required to operate the pumps = 20 × 0.00103 [6000 - 50] = 122.57 kW.

The power produced by the turbine = 20 [ 300 - ( the fourth enthalpy value)].

The fourth enthalpy value = 3300 - 0.94 [ 3300 - 2340] = 2397.6 kJ/kg

Thus, the power produced by the turbine = 20 [ 300 - 2397.6] = 18048 kW.

The power produced by the turbine  =  18048 kW.

The net power produced =  18048  + 122.57 = 17925 kW.

The thermal efficiency = [net power produced] / [the rate at which heat is added in the boiler].

The thermal efficiency = 17925/ 59597.4 = 30%.

Answer:

- the difference in pressure between the given systolic and diastolic readings in KPa is 5.313 KPa

- the difference in pressure between the given systolic and diastolic readings in psi is 0.77 psi

Explanation:

Given the data in the question;

blood pressure reading = 120 and 80 { systolic and diastolic }

To determine the difference in pressure between the two readings, we use the equation as follows;

change in pressure ΔP = p × g × h

where p is mercury density, g is acceleration due to gravity and h is difference of height in mercury column.

Frist,  

difference of height in mercury column h = 120 - 80 = 40 mm = 0.04 m

given that; The density of mercury is 13.54 Mg/m³ = 13.54 × 10³ kg/m³

Not that Mg is Megagrams not Milligrams }

we know that g = 9.81 m/s²

so we substitute into our equation;

change in pressure ΔP = (13.54 × 10³) × 9.81 × 0.04

ΔP = 5313.096 kg/m-s² ≈ 5313.096 N/m²

ΔP = 5.313 KPa

Therefore, the difference in pressure between the given systolic and diastolic readings in KPa is 5.313 KPa.

In psi,

ΔP = 5.313 KPa

ΔP = 5313 Pa

ΔP = 5313 pa × ( 1.45 × 10⁻⁴ psi / 1 Pa )

ΔP = 0.770385 psi ≈ 0.77 psi

Therefore, the difference in pressure between the given systolic and diastolic readings in psi is 0.77 psi

Answer: 72 inches!

Explanation:

The length of the rectangular yard in inches is 72 inches. This is calculated by using the perimeter formula, p = 2l + 2w, and substituting the known values: p = 2(18 feet) + 2(4 feet). This simplifies to p = 36 feet + 8 feet, which is equal to 44 feet. To convert this to inches, we multiply 44 feet by 12 inches per foot, which gives us a total of 528 inches. Therefore, the length of the rectangular yard in inches is 72 inches.

Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.

Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.
