(a) Flowchart: A condenser process flowchart is provided, illustrating the inputs and outputs of the humid air stream, O₂, N₂, and the condensed liquid water. (b) Total flow rate: The total flow rate of the feed stream entering the condenser is 5.296F mol/s, considering the flow rates of water vapor, O₂, and N₂. (c) Enthalpy and heat transfer: The enthalpy changes for water vapor and O₂ are calculated, resulting in a heat transfer of -0.072 kF kW, indicating heat removal by the condenser. the heat transferred by the condenser is -0.072 kF kW.

(a) Flowchart:

(b) Total flow rate of the feed stream:

The flow rate of N2 leaving the condenser is given as 5.18 mol/s.

The flow rate of water vapor entering the condenser is 58.0 mol% of F.

80% of the above water vapor is condensed and removed, leaving 20% remaining.

So, 20% of the above water vapor remaining in the humid air after condensation is 0.116F mol/s.

The flow rate of O2 is given as 8.8 mol% of F.

The total flow rate of the feed stream is the sum of the flow rates of water vapor, O2, and N2:

Total flow rate = Flow rate of water vapor + Flow rate of O2 + Flow rate of N2

              = 0.116F + 0.088F + 5.18

              = 5.296F mol/s

(c) Inlet-Outlet Enthalpy Table:

To calculate the heat transferred by the condenser, we need to determine the enthalpy changes for water vapor (H3 to H4) and O2 (H5).

The enthalpy change for water vapor can be calculated as:

ΔH_vap = Enthalpy of water vapor at 30°C - Enthalpy of water vapor at 150°C

      = [40.657 + 0.119 × (30 - 0)] - [40.657 + 0.119 × (150 - 0)]

      = -13.607 kJ/kmol

Enthalpy of water leaving the condenser (H4) can be calculated as:

H4 = Enthalpy of water vapor at 30°C = 40.657 kJ/kmol

Enthalpy of O2 leaving the condenser (H5) can be taken as:

H5 = Enthalpy of O2 at 30°C = 0.102 kJ/kmol

The heat transferred by the condenser (q) can be calculated as:

q = Total flow rate × ΔH

 = (5.296F mol/s) × (-13.607 kJ/kmol) × 10⁻³ kW/J

 = -0.072 kF kW (where kF is the constant conversion factor 10⁶)

Therefore, the heat transferred by the condenser is -0.072 kF kW.

Answer:

La magnitud de la masa del peso es 78.447 libras-masa.

Explanation:

La tensión es una fuerza de reacción de la cuerda causada por la acción de una fuerza externa. En este caso, esa fuerza externa es el peso que cuelga en el centro de la cuerda. Abajo hemos adjuntado una representación simplificada del enunciado.

Por las leyes de Newton, tenemos la siguiente ecuación de equilibrio conformada por tres fuerzas:

\(\vec T_{1} + \vec T_{2} + \vec W = (0, 0)\, [N]\) (1)

Donde:

\(\vec T_{1}\), \(\vec T_{2}\) - Tensiones a cada lado de la cuerda, en newtons.

\(\vec W\)- Peso, en newtons.

Si sabemos que \(\vec T_{1} = T\cdot (\cos \alpha, \sin \alpha)\), \(\vec T_{2} = T\cdot (-\cos \alpha, \sin \alpha)\) y \(\vec W = W\cdot (0, -1)\), entonces tenemos la siguiente ecuación vectorial:

\(T\cdot (\cos \alpha, \sin \alpha) + T\cdot (-\cos\alpha, \sin \alpha) + W\cdot (0, -1) = (0,0)\)

\(T\cdot (0, 2\cdot \sin \alpha) = W\cdot (0, 1)\)

Esto permite reducir la anterior expresión a una fórmula escalar:

\(2\cdot T\cdot \sin \alpha = W\)

Donde \(\alpha\) es el ángulo de inclinación de la cuerda, medido en grados sexagesimales.

El ángulo de inclinación de la cuerda se determina mediante la siguiente fórmula trigonométrica inversa es:

\(\alpha = \tan^{-1} \left(\frac{2\,ft}{10\,ft}\right)\)

\(\alpha \approx 11.310^{\circ}\)

Si conocemos que \(\alpha \approx 11.310^{\circ}\) y \(T = 200\,lbf\), entonces la magnitud del peso es:

\(W = 2\cdot (200\,lb)\cdot \sin 11.310^{\circ}\)

\(W \approx 78.447\,lbf\)

En el Sistema Imperial, las fuerzas son medidas en forma gravitacional, entonces la magnitud de la fuerza gravitacional del peso equivale a la magnitud de su masa. En síntesis, la magnitud de la masa es \(78.447\,lbm\).

La magnitud de la masa del peso es 78.447 libras-masa.

The wavelength in picometers of light with a frequency of 9.3 × 1018 hz would be 32 pm.

Wavelength is the separation between a wave's starting point and its ending position. The frequency is the quantity of waves passing through a spot every second.

Wavelength and frequency have a connection to energy just as they do to light. Higher frequency and shorter wavelengths are correlated with more energy. Hence, lower energy is produced when the wavelengths are longer and the frequency is lower.

Indirect proportionality exists between frequency and wavelength. Greater wavelengths result in lower frequencies, and vice versa. The relationship between frequency and wavelength is explained by the fact that the speed of a wave is equal to the product of these two numbers.

Let the equation be v = c/λ

Frequency of 9.3 × 1\(0^{18\)

9.3 × 1\(0^{18\) = 3.00*1\(0^8\) / λ

simplifying the equation, we get

λ = 3.001\(0^8\) / 9.3 × 1\(0^{18\)

= 3.2 1\(0^{25\) m 1pm/ 1\(0^{-12\)

= 3.2 1\(0^{37\)

Answer:

4.

Distance:

Total distance traveled is the sum of the distances for each leg of the journey:

Distance = 100 + 200 + 150 + 50 + 75 + 400 + 25 = 1000 m

Therefore, the person traveled a total distance of 1000 m.

5.

Displacement:

Displacement is the straight-line distance from the starting point to the ending point, taking into account direction.

To find the displacement, we need to add up all the distances traveled in the North direction and subtract the distances traveled in the South direction:

Displacement = (100 + 50 + 75) - (200 + 150 + 400 + 25) = -550 m

The negative sign indicates that the person ended up 550 m South of the starting point.

6.

Speed:

Speed is the distance traveled divided by the time it took to travel that distance:

Speed = Distance / Time

The total time taken is 500 seconds, and the total distance traveled is 1000 m, so:

Speed = 1000 / 500 = 2 m/s

Therefore, the person's average speed was 2 m/s.

7.

Velocity:

Velocity is the displacement divided by the time it took to travel that distance:

Velocity = Displacement / Time

The displacement is -550 m, and the total time taken is 500 seconds, so:

Velocity = -550 / 500 = -1.1 m/s

The negative sign indicates that the person was traveling Southward.

Therefore, the person's average velocity was -1.1 m/s.

8.

Time to walk a metric mile:

A metric mile is 1609.34 m.

The person's average speed was 2 m/s, so the time it should take to walk a metric mile is:

Time = Distance / Speed = 1609.34 / 2 = 804.67 seconds

Therefore, it should take the person 805 seconds or 13 minutes and 25 seconds to walk a metric mile.

9.

Percent error:

The actual time taken to walk a metric mile was 880 seconds. The percent error is:

% Error = [(Theoretical Time - Actual Time) / Theoretical Time] x 100%

% Error = [(805 - 880) / 805] x 100% = -9.3%

The negative sign indicates that the actual time taken was faster than the theoretical time. The percent error is 9.3%.

10.

Acceleration of a Porsche 911 GT3:

The acceleration of a Porsche 911 GT3 is reported to be 0-60 mph in 2.7 seconds.

To convert this to mph/s, we need to divide the change in velocity (60 mph) by the time (2.7 s):

Acceleration = 60 / 2.7 = 22.2 mph/s

Therefore, the acceleration of a Porsche 911 GT3 is 22.2 mph/s.

11.

Time to reach top speed:

The top speed of a Porsche 911 GT3 is reported to be 198 mph.

Starting from 60 mph, the change in velocity required to reach the top speed is:

Change in velocity = 198 - 60 = 138 mph

To find the time it takes to reach this change in velocity, we can use the following equation:

Change in velocity = Acceleration x Time

Solving for time:

Time = Change in velocity / Acceleration = 138 / 22.2 = 6.2 seconds

Therefore, it should take the Porsche 911 GT3 6.2 seconds to reach its top speed if it starts from 60 mph.

The polymer with the highest surface tension, in this case, is Polymer A with a surface tension of 75 dynes/cm. Therefore, Polymer A will have the most tendency to interact with an anionic surfactant such as SDS.

Surface tension is a measure of the cohesive forces between molecules at the surface of a liquid.

A higher surface tension indicates stronger intermolecular forces and greater resistance to disruption of the liquid's surface.

Anionic surfactants, such as SDS (sodium dodecyl sulfate), have a negatively charged hydrophilic head group. They are attracted to positively charged or polar surfaces, promoting adsorption and reducing surface tension.

Since Polymer A has the highest surface tension among the given polymers, it suggests that it has stronger cohesive forces and a higher degree of interaction between its molecules.

This increased tendency to interact makes Polymer A more favorable for the adsorption of an anionic surfactant like SDS.

Polymers B, C, and D have progressively lower surface tensions, indicating weaker intermolecular forces and reduced interaction with anionic surfactants compared to Polymer A.

The estimated potential at point P (4,5,6) taking V = 0 V at (0,0,0) is 12.204 V.

Electric potential at point P due to a point charge q is given as; V=kq/r Where V is the electric potential, q is the charge of the particle producing electric potential, k is the Coulomb's constant and r is the distance between the point charge and the point where electric potential is to be determined.  At point P (4,5,6), the distance from the point charge of 10nC to P is given as;

√[(4−2)^2+(5−10)^2+(6−3)^2] = √54 = 7.348m.

So, the potential due to the point charge at point P is;

V1=kq/r1 = 9×10^9 × 10 × 10^−9/7.348 V1=12.2 V.

Now, for the potential at point P due to the line of charge, we will need to first calculate the linear charge density (λ) of the line of charge.λ=q/l,  Where λ is the linear charge density, q is the total charge on the line and l is the length of the line.  For the line of charge Y=2, Z=2, the total charge is given as;  Q=λlWhere Q is the total charge and l is the length of the line.  Since the line is infinite, we cannot use the length of the line, we will use the length of the portion of the line from (0,2,2) to (0,-2,2) which is 4 units long.  We can then find the length of the portion of the line from (-∞,2,2) to (0,2,2) which is half of the entire line. Using the Pythagoras theorem, the length of this portion is given by;

√[4^2+(2−2)^2+(2−2)^2] = √16 = 4m.  Then the linear charge density is;

λ=Q/l = 5×10−9 C/4m = 1.25×10−9 C/m.  The electric potential at point P due to the line of charge can be determined using the equation below; V2=λ/2πε0.  ln(b/a) Where V2 is the electric potential, λ is the linear charge density, ε0 is the permittivity of free space, b is the distance between point P and the end of the line of charge and a is the distance between point P and the other end of the line of charge. To calculate V2, we will need to find b and a. The distance between point P and the end of the line of charge is given as;

√[(0−4)^2+(2−5)^2+(2−6)^2] = √45 = 6.708m.  

The distance between point P and the other end of the line of charge is given as;

√[(0−4)^2+(−2−5)^2+(2−6)^2] = √74 = 8.602m.  

So, V2 is; V2=1.25×10−9/2π×9×10^9  ln(8.602/6.708) V2=0.004 V

The total electric potential at point P is the sum of the electric potential due to the point charge and that due to the line of charge.

Thus; VT=V1+V2 = 12.2+0.004 = 12.204 V

Explanation:

Therefore, the electric force experienced by the 100 mg bee with a charge of 23 pc in the Earth's electric field is 2.3 × 10⁻¹⁰newtons, directed downward.

When a honeybee flies through the air, it acquires a charge due to friction with the air. In this case, the bee has a charge of 23 pc (picocoulombs) and weighs 100 mg (milligrams). The bee experiences an electric force in the Earth's electric field, which is typically 100 N/C (newtons per coulomb), directed downward.

To calculate the electric force experienced by the bee, we can use the formula:

Electric force = charge × electric field

Substituting the given values into the formula, we have:

Electric force = (23 pc) × (100 N/C)

Now, we need to convert the charge from picocoulombs to coulombs. One picocoulomb is equal to 10^-12 coulombs. Therefore, 23 pc is equal to 23 × 10⁻¹² C.

Substituting the converted charge value into the formula, we have:

Electric force = (23 × 10⁻¹² C) × (100 N/C)

Simplifying the calculation, we get:

Electric force = 2.3 × 10⁻¹⁰ N

Therefore, the electric force experienced by the 100 mg bee with a charge of 23 pc in the Earth's electric field is 2.3 × 10⁻¹⁰newtons, directed downward.
