To develop a closed-form equation for the velocity of the ice sphere as a function of time, we need to consider the forces acting on the sphere: drag force and melting rate.

1. Drag force:

Using the Stokes equation, the drag force can be expressed as:

f_drag = 6πηru

2. Melting rate:

The melting rate of the ice sphere can be given as:

dm/dt = -cA

3. Equation of motion:

Applying Newton's second law, we have:

m(dv/dt) = -f_drag

Since the mass (m) of the ice sphere is changing due to melting, we can express it as:

m = (4/3)πr^3ρ

where ρ is the density of the ice sphere.

Combining the above equations, we get:

(4/3)πr^3ρ(dv/dt) = -6πηru - cA

Simplifying the equation and solving for dv/dt, we obtain:

dv/dt = (-6η/ρr)u - (3cA)/(4πr^3ρ)

This is a first-order linear ordinary differential equation (ODE) that describes the velocity (v) as a function of time (t) for the melting ice sphere in a fluid medium.

Note: Solving this ODE would require initial conditions and integration techniques based on the specific problem parameters and assumptions. The resulting closed-form equation for velocity as a function of time would depend on the specific values of η, ρ, r, c, A, u0, and r0.

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.

The concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

To determine the concentration ratio and length of the parabolic surface for a Parabolic Trough Collector (PTC) with the given parameters, we can use the following formulas:

Concentration Ratio (CR) = Rim Angle / Aperture Angle

Length of Parabolic Surface (L) = Aperture^{2} / (16 * Focal Length)

First, let's calculate the concentration ratio:

Given:

Rim Angle (θ) = 80º

Aperture Angle (α) = 5.2 m

Concentration Ratio (CR) = 80º / 5.2 m

Converting the rim angle from degrees to radians:

θ_rad = 80º * (π / 180º)

CR = θ_rad / α

Next, let's calculate the length of the parabolic surface:

Given:

Aperture (A) = 5.2 m

Receiver Diameter (D) = 50 mm = 0.05 m

Focal Length (F) = A^{2} / (16 * D)

L = A^{2} / (16 * F)

Now we can substitute the given values into the formulas:

CR =\((80º * (π / 180º)) / 5.2 m\)

L = \((5.2 m)^2 / (16 * (5.2 m)^2 / (16 * 0.05 m))\)

Simplifying the equations:

CR ≈ 1.48

L ≈ 5.2 m

Therefore, the concentration ratio for the PTC is approximately 1.48, and the length of the parabolic surface is approximately 5.2 meters.

This question is incomplete, the complete question is;

For a steel alloy it has been determined that a carburizing heat treatment of 11.3 h duration at Temperature T1 will raise the carbon concentration to 0.44 wt% at a point 1.8 mm from the surface. A separate experiment is performed at T2 that doubles the diffusion coefficient for carbon in steel.

Estimate the time necessary to achieve the same concentration at a 4.9 mm position for an identical steel and at the same carburizing temperature T2.

Answer:

the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Explanation:

Given the data in the question;

treatment time t₁ = 11.3 hours

Carbon concentration = 0.444 wt%

thickness at surface x₁ = 1.8 mm = 0.0018 m

thickness at identical steel x₂ = 4.9 mm = 0.0049 m

Now, Using Fick's second law inform of diffusion

\(x^2\) / Dt = constant

where D is constant

then

\(x^2\) / t = constant

\(x^2_1\) / t₁ = \(x^2_2\) / t₂

\(x^2_1\) t₂ = t₁\(x^2_2\)

t₂ = t₁\(x^2_2\) / \(x^2_1\)

t₂ = (\(x^2_2\) / \(x^2_1\))t₁

t₂ = \((\) \(x_2\) / \(x_1\) \()^2\) × t₁

so we substitute

t₂ = \((\) 0.0049  / 0.0018  \()^2\) × 11.3 hrs

t₂ = 7.41 × 11.3 hrs

t₂ = 83.733 hrs

Therefore, the required time to achieve the same concentration at a 4.9 is 83.733 hrs

Explanation:

Given that:

\([\sigma] = \left[\begin{array}{cc}800&300\\ \\300&-400\end{array}\right] (MPa)\)

\([\sigma] = \left[\begin{array}{cc}\sigma_{xx}&\sigma_{xy}\\ \\\sigma_{yx}&\sigma_{yy}\end{array}\right]\)

Using Determinant method

The principal stress is the maximum or minimum normal stress acting on any plane. For the 2D stress system, the 2-principle plane always carries zero shear stress.

For principal stress \(( \sigma_1, \sigma_2)\)

\(\sigma_{1,2} = \dfrac{\sigma_x+ \sigma_y}{2} \pm \sqrt{( \dfrac{\sigma_x - \sigma_y}{2} )^2 + \sigma^2_{xy}}\)

\(\sigma_{1} = \dfrac{800+(-400)}{2} \pm \sqrt{( \dfrac{800 -(-400)}{2} )^2 + (300)^2}\)

\(\sigma_{1} = \dfrac{400}{2} \pm \sqrt{ (600)^2 + (300)^2}\)

\(\sigma_{1} = 200+ 670.82 \\ \\ \sigma_{1} = 870.82 \ MPa\)

\(\sigma_{2} = \dfrac{800+(-400)}{2} \pm \sqrt{( \dfrac{800 -(-400)}{2} )^2 + (300)^2}\)

\(\sigma_{2} = 200- 670.82 \\ \\ \sigma_{1} = - 470.82 \ MPa\)

According to Mohr's circle;

Mohr's circle is the locus provided that the position of the normal stress and the shear stress is acting on any plane.

Center = (a,0)

\(a = \dfrac{\sigma_{x}+\sigma_{y}}{2}\)

\(a = \dfrac{800+(-400)}{2}\)

a = 200 MPa

radius (r) = \(\sqrt{ (\dfrac{\sigma_{x}-\sigma_{y}}{2})^2 + \sigma^2 _{xy}}\)

\(=\sqrt{ (\dfrac{800-(-400)}{2})^2 + (300)^2}\)

\(=\sqrt{ (600)^2 + (300)^2}\)

r = 670.82 MPa

\(\sigma_1 = a +r \\ \\ \sigma_1 = 200 + 670.82 \\ \\ \sigma_1 = 870.82 \ MPa\)

\(\sigma_2 =-(r-a)\)      (it is negative because of the negative x-axis)

\(\sigma_2 =670.82 - 200 \\ \\ \sigma_1 = 470.82 \ MPa\)
