A decimal system conversion chart is used to ____ and find equal values for ___ and ___

Answer:

The specific volume is reduced in 80 per cent due to isothermal compression.

Specific enthalpy remains constant.

Explanation:

Let suppose that neon behaves ideally, the equation of state for ideal gases is:

\(P\cdot V = n\cdot R_{u}\cdot T\)

Where:

\(P\) - Pressure, measured in kilopascals.

\(V\) - Volume, measured in cubic meters.

\(n\) - Molar quantity, measured in kilomoles,

\(T\) - Temperature, measured in kelvins.

\(R_{u}\) - Ideal gas constant, measured in \(\frac{kPa\cdot m^{3}}{kmol\cdot K}\).

On the other hand, the molar quantity (\(n\)) and specific volume (\(\nu\)), measured in cubic meter per kilogram, are defined as:

\(n = \frac{m}{M}\) and \(\nu = \frac{V}{m}\)

Where:

\(m\) - Mass of neon, measured in kilograms.

\(M\) - Molar mass of neon, measured in kilograms per kilomoles.

After replacing in the equation of state, the resulting expression is therefore simplified in term of specific volume:

\(P\cdot V = \frac{m}{M}\cdot R_{u}\cdot T\)

\(P\cdot \nu = \frac{R_{u}\cdot T}{M}\)

Since the neon is compressed isothermally, the following relation is constructed herein:

\(P_{1}\cdot \nu_{1} = P_{2}\cdot \nu_{2}\)

Where:

\(P_{1}\), \(P_{2}\) - Initial and final pressure, measured in kilopascals.

\(\nu_{1}\), \(\nu_{2}\) - Initial and final specific volume, measured in cubic meters per kilogram.

The change in specific volume is given by the following expression:

\(\frac{\nu_{2}}{\nu_{1}} = \frac{P_{1}}{P_{2}}\)

Given that \(P_{1} = 100\,kPa\) and \(P_{2} = 500\,kPa\), the change in specific volume is:

\(\frac{\nu_{2}}{\nu_{1}} = \frac{100\,kPa}{500\,kPa}\)

\(\frac{\nu_{2}}{\nu_{1}} = \frac{1}{5}\)

The specific volume is reduced in 80 per cent due to isothermal compression.

Under the ideal gas supposition, specific enthalpy is only function of temperature, as neon experiments an isothermal process, temperature remains constant and, hence, there is no change in specific enthalpy.

Specific enthalpy remains constant.

Answer:

The specimen would not fracture having a flexural strength ( 300 MPa ) > ( 286.5 MPa )

Explanation:

The expression to represent  the stress on a cylindrical specimen  by a three-point transverse bending test

б =  \(\frac{F_{f}L }{\pi R^3}\)  ---------------- ( 1 )

where : R = radius, Ff = flexural load,

L = distance between loads ( two loads )

Given data:

7500 N =  flexural load

(15 * 10^-3) m =  distance between loads

(5 * 10^-3) m  =  radius

input the given values into equation 1

б = 286.5 * 10^6 N/m^2   =  286.5 MPa

Note : the flexural strength of the cylindrical specimen is 300MPa

Therefore the specimen would not fracture having a flexural strength ( 300 MPa ) > ( 286.5 MPa )

The elasticity of demand for oil when the price is $79 per barrel is approximately -0.052.

The elasticity of demand measures the responsiveness of quantity demanded to changes in price. In this case, the elasticity of demand is calculated by taking the derivative of the demand function with respect to price, and then multiplying it by the ratio of price to quantity.

To calculate the elasticity at a specific price, we need to differentiate the demand function with respect to price, which gives us -0.05 * 2,144,309 * p^(-0.05 - 1). Simplifying this expression gives us -107,215.45 * p^(-1.05).

Next, we multiply this expression by the ratio of price to quantity. At a price of $79 per barrel, we substitute p = 79 into the expression and divide it by the quantity consumed. This gives us (-107,215.45 * 79^(-1.05)) / (2,144,309 * 79^(-0.05)). Simplifying further, we find the elasticity to be approximately -0.052.

Interpreting this elasticity value, we can say that a 1% increase in the price of crude oil would result in a approximately 0.052% decrease in per capita consumption of crude oil in Country A in 2008. Similarly, a 1% decrease in price would lead to a 0.052% increase in per capita consumption. This indicates that the demand for oil in Country A is relatively inelastic, meaning that changes in price have a proportionately smaller impact on the quantity demanded.

Answer: The inside diameter is approximately 0.39 meters and the outside diameter is approximately 0.65 meters.

Explanation:

The first step is to calculate the torque required to transmit 1.5 MW of power at 1500 rpm. The formula for torque is:

T = (P × 60) / (2 × π × N)

where T is torque, P is power, N is speed in revolutions per minute, and π is the mathematical constant pi. Substituting the given values, we get:

T = (1.5 × 10^6 × 60) / (2 × π × 1500) = 238.7 kNm

Next, we can use the formula for shear stress:

τ = (T × r) / J

where τ is shear stress, T is torque, r is the radius, and J is the polar moment of inertia. For a tube, J is equal to (π/2) × (D^4 - d^4), where D is the outside diameter and d is the inside diameter.

Since the ratio of inside diameter to outside diameter is 0.6, we can set d = 0.6D. Substituting this into the formula for J and simplifying, we get:

J = (π/2) × D^4 × (1 - 0.6^4) = 0.374πD^4

Substituting the given values for torque and shear stress, we get:

500 kPa = (238.7 kNm × r) / (0.374πD^4)

Solving for r/D, we get:

r/D = 0.054

Since r + d = D, we can substitute d = 0.6D and r = 0.054D into this equation and solve for D:

D = 0.65 meters (approx.)

Finally, we can calculate the inside diameter by using the given ratio:

d/D = 0.6

d = 0.39 meters (approx.)

Therefore, the inside diameter is approximately 0.39 meters and the outside diameter is approximately 0.65 meters.

The activation energy for the production of vacancies is determined to be 1.23 eV by measuring increases in the resistivity of platinum wires caused by quenching. The concentration of vacancies is 10-'-10-s at the melting point.

After quenching down to 4 K and under extremely low vacancy concentrations for ultrahigh purity aluminum, the formation energy of vacancies is determined. The result is determined to be (0.69 & 0.03) eV. The formation energy obtained from similar tests using pure magnesium is (0.79 f 0.03) eV. In order to compute the rate, multiply the number of unoccupied units by 100, then divide the resulting amount by the overall number of units. The sum of the occupancy rate and vacancy rate should be 100 percent. As a result, a 300-unit apartment complex with 30 vacant units has a 10% vacancy rate.

The optimal solution is to produce 45 units of X and 5 units of Y to meet the demand—stock at the end of the week: 0 units of X and 0 units of Y.

To maximize the combined sum of units X and Y in stock at the end of the week, we must determine how many units of X and Y can be produced given the available machine processing time.

Convert machine hours to minutes: Machine A = 40 * 60 = 2400 minutes; Machine B = 35 * 60 = 2100 minutes.

Set up equations for machine time: 50X + 24Y <= 2400 (Machine A); 30X + 33Y <= 2100 (Machine B).

Given initial stock and demand, calculate the remaining units needed: X = 75 - 30 = 45; Y = 95 - 90 = 5.

Find production quantities within constraints that maximize stock (use Integer Linear Programming or trial-and-error method).

Explanation:

Given the attached series-parallel circuit, you want to know ...

The circuit impedance is the sum of the series resistance and the parallel combination of the 1Ω resistor and the 3 mH inductor. For ω = 333, the inductor's impedance is Xl = jωL = j(333)(.003)Ω = j0.999Ω.

The total impedance is the sum ...

  Ztot = 10 + 1/(1/1 +1/j0.999) = 10.51∠2.73°

The total current in the circuit is ...

  Is = Vs/Ztot = 10∠45°/10.51∠2.73° = 0.9513∠42.27°

The branch currents are in reverse proportion to the branch impedance

  Ir = Is(Xl/(1+Xl)) = 0.6724∠87.30°

  Il = Is(1/(1+Xl)) = 0.6730∠-2.70°

Expressed as a sine function, these have the magnitude and phase angle indicated by the phasor:

  Is(t) = 0.9513·sin(333t +42.27°)

  Ir(t) = 0.6724·sin(333t +87.30°)

  Il(t) = 0.6730·sin(333t -2.70°)

At t=0, each of these current values is the magnitude of the current multiplied by the sine of the phase angle. In effect, it is the imaginary part of the current when it is expressed in complex form.

  Is(0) = 0.9513·sin(42.27°) = 0.6399 A

  Ir(0) = 0.6724·sin(87.30°) = 0.6716 A

  Il(0) = 0.6730·sin(-2.70°) = -.0317 A

In Java, a variable can be declared using the byte data type that can store an 8-bit signed two's complement integer with a minimum value of -128 and a maximum value of 127. The bytecode of this code is obtained by the following process: The byte b variable is declared and initialized to a value of 6.

The byte data type is used to store 8-bit signed two's complement integers. The following line assigns the value of b + 8 to b, which results in 14. System.out. println (b) prints the value of b, which is 14 at this point. The following line attempts to assign the value of b + 7 to b, but b has already reached its maximum value (127), so it wraps around to -128.

As a result, b is assigned a value of -117 (-128 + 7 = -121, but 127 is subtracted from this to obtain -117). System.out. println (b) prints the value of b, which is -117 at this point. The bytecode generated by this code is as follows: public class Test {public static void main(String[] args) {byte b = 6;b += 8; System. out. println(b);b = b + 7; System.out. println(b);}} This code produces the following output when run: 14-117

The torque M which must be applied to the crank at O when the crank angle = 30° is 0.5 Nm.

Taking moments about O, the torque is given byτ = (AB x BC) sin(θ) x a

Here θ is the angle between AB and the horizontal and a is the tangential acceleration of B.θ is 180° - 2α and sin(θ) = sin(2α), where α is the angle between the coupler and AB.

Angle α is given byα = cos⁻¹((BC² - AC² - AB²) / (-2AC x AB))

The tangential acceleration of B is given by

a = (BC x AB x ω²) / (2 x BD)

where BD is the perpendicular distance from O to AB.

Calculating angle α

α = cos⁻¹((BC² - AC² - AB²) / (-2AC x AB))

α = cos⁻¹((1.5² - 0.8² - 0.9²) / (-2x0.8x0.9))

α = cos⁻¹(-0.263)α = 104.33°

Calculating θ

θ = 180° - 2α

θ = 180° - 2(104.33°)

θ = - 16.67°

We can take sinθ = sin(-16.67°) = -0.29.
