Explanation:

Given that,

The area of glass \(A_g\) = \(0.11m^2\)

The thickness of the glass \(t_g=4mm=4\times10^-^3m\)

The area of the styrofoam \(A_s=11m^2\)

The thickness of the styrofoam \(t_s=0.20m\)

The thermal conductivity of the glass \(k_g=0.80J(s.m.C^o)\)

The thermal conductivity of the styrofoam  \(k_s=0.010J(s.m.C^o)\)

Inside and outside temperature difference is ΔT

The heat loss due to conduction in the window is

\(Q_g=\frac{k_gA_g\Delta T t}{t_g} \\\\=\frac{(0.8)(0.11)(\Delta T)t}{4.0\times 10^-^3}\\\\=(22\Delta Tt)j\)

The heat loss due to conduction in the wall is

\(Q_s=\frac{k_sA_s\Delta T t}{t_g} \\\\=\frac{(0.010)(11)(\Delta T)t}{0.20}\\\\=(0.55\Delta Tt)j\)

The net heat loss of the wall and the window is

\(Q=Q_g+Q_s\\\\=\frac{k_gA_g\Delta T t}{t_g}+\frac{k_sA_s\Delta T t}{t_g}\\\\=(22\Delta Tt)j +(0.55\Delta Tt)j \\\\=(22.55\Delta Tt)j\)

The percentage of heat lost by the window is

\(=\frac{Q_g}{Q}\times 100\\\\=\frac{22\Delta T t}{22.55\Delta T t}\times 100\\\\=97.6 \%\)

Calculate the equivalent capacitance of the three series capacitors in Figure 12-1

a) 0.01 μF

b) 0.58 μF

c) 0.060 μF

d) 0.8 μF

Answer:

The equivalent capacitance of the three series capacitors in Figure 12-1 is 0.060 μF

Therefore, the correct option is (c)

Explanation:

Please refer to the attached Figure 12-1 where three capacitors are connected in series.

We are asked to find out the equivalent capacitance of this circuit.

Recall that the equivalent capacitance in series is given by

\($ \frac{1}{C_{eq}} = \frac{1}{C_{1}} + \frac{1}{C_{2}} + \frac{1}{C_{3}} $\)

Where C₁, C₂, and C₃ are the individual capacitance connected in series.

C₁ = 0.1 μF

C₂ = 0.22 μF

C₃ = 0.47 μF

So the equivalent capacitance is

\($ \frac{1}{C_{eq}} = \frac{1}{0.1} + \frac{1}{0.22} + \frac{1}{0.47} $\)

\($ \frac{1}{C_{eq}} = \frac{8620}{517} $\)

\($ C_{eq} = \frac{517}{8620} $\)

\($ C_{eq} = 0.0599 $\)

Rounding off yields

\($ C_{eq} = 0.060 \: \mu F $\)

The equivalent capacitance of the three series capacitors in Figure 12-1 is 0.060 μF

Therefore, the correct option is (c)

Explanation:

First, we determine the stress on the rod:

\(\sigma = \frac{F}{A}\\\\\)

where,

σ = stress = ?

F = Force Applied = 1300 lb

A = Cross-sectional Area of rod = 0.5\(\pi \frac{d^2}{4} = \pi \frac{(0.5\ in)^2}{4} = 0.1963\ in^2\)

Therefore,

\(\sigma = \frac{1300\ lb}{0.1963\ in^2} \\\\\sigma = 6.62\ kips\)

Now, we determine the strain:

\(strain = \epsilon = \frac{elongation}{original\ length} \\\\\epsilon = \frac{0.009\ in}{12\ in}\\\\\epsilon = 7.5\ x\ 10^{-4}\)

The PVC is located at station 30+20.55 and has an elevation of 752.67 ft, while the PVT is located at station 30+60.55 and also has an elevation of 752.67 ft.

What is PVC?

Point of Vertical Curvature is referred to as PVC. The point on a vertical curve where the road slope switches from uphill to downhill or vice versa is known as the "turnaround point." The PVC is where the road's curve switches from convex to concave, or the other way around. On a sag curve, the PVC is the highest point, and on a crest curve, the lowest. Because it has an impact on the visibility and safety of the road, it is crucial in the design of highways and civil engineering.

First, we need to find the elevations of the two grades at station 30+60.55. We can use the following equation to do this:

Elevation = Elevation of Intersection Point + (Grade × Distance)

For the 5 grade:

Elevation = 748.64 + (0.05 × 60.55) = 751.67 ft

For the 3 grade:

Elevation = 748.64 + (0.03 × 60.55) = 750.83 ft

Since the elevation of the 5 grade is higher than the elevation of the 3 grade at the intersection point, this is a sag curve.

To find the location and elevation of the PVC and PVT, we can use the following equations:

PVC Elevation = Elevation of Intersection Point + (Grade Difference/100) × (Distance/2)²

PVT Elevation = Elevation of Intersection Point + (Grade Difference/100) × (Distance/2)²

PVC Station = Intersection Station – (Distance/2)

PVT Station = Intersection Station + (Distance/2)

Where:

Grade Difference = 0.05 - 0.03 = 0.02

Distance = 800 ft

PVC Elevation = 751.67 + (0.02/100) × (800/2)² = 752.67 ft

PVT Elevation = 751.67 + (0.02/100) × (800/2)² = 752.67 ft

PVC Station = 30+60.55-(800/2) = 30+20.55 = 30+20+0.55 = 30+20.55

PVT Station = 30+60.55+(800/2) = 30+60+0.55 = 30+60.55

Therefore, the PVC is located at station 30+20.55 and has an elevation of 752.67 ft, while the PVT is located at station 30+60.55 and also has an elevation of 752.67 ft.

Explanation: made more sense

(a) The Young's modulus of the reinforcing steel bar is usually taken to be 29,000 ksi. (b) The term 'grade' on a reinforcing steel bar represents the strength of steel. The strength is determined by the steel's yield strength or the stress at which steel starts deforming or yielding.

(c) The nearly yield strain of Grade-80 steel is about 0.008. Explanation: Reinforcing steel bars are used in reinforced concrete to give the concrete tensile strength to resist cracking and also resist the weight of structures and live loads. These bars are made of high-quality steel and must comply with several standards and specifications like ASTM or ACI.

Reinforcing steel bars are classified by grades according to their tensile strength. The grade is indicated by a number that ranges from 40 to 100 based on the steel's yield strength. The most commonly used grades are 40, 60, and 80, with 80 being the highest.

This means that Grade-80 steel is stronger than Grade-60 and Grade-40.The Young's modulus of steel refers to its elasticity, i.e., its ability to stretch and then return to its original shape. The Young's modulus of reinforcing steel bars is generally considered to be 29,000.

Answer:

final temperature = 26.5°

Explanation:

Initial volume of water is 1 x 1 x 1 = 1 \(m^{3}\)

Initial temperature of water = 20° C

Density of water = 1000 kg/\(m^{3}\)

volume of copper block = 0.46 x 0.46 x 0.46 = 0.097 \(m^{3}\)

Initial temperature of copper block = 100° C

Density of copper = 8960 kg/\(m^{3}\)

Final volume of water = 1 - 0.097 = 0.903 \(m^{3}\)

Assumptions:

mass of water remaining in the tank will be density x volume = 1000 x 0.903 = 903 kg

specific heat capacity of water c = 4186 J/K-kg

heat content of water left Hw = mcT = 903 x 4186 x 20 = 75.59 Mega-joules

mass of copper will be density x volume = 8960 x 0.097 = 869.12 kg

specific heat capacity of copper is 385 J/K-kg

heat content of copper Hc = mcT = 869.12 x 385 x 100 = 33.46 Mega-joules

total heat in the system = 75.59 + 33.46 = 109.05 Mega-joules

this heat will be distributed in the entire system

heat energy of water within the system = mcT

where T is the final temperature

= 903 x 4186 x T = 3779958T

for copper, heat will be

mcT = 869.12 x 385 = 334611.2T

these component heats will sum up to the final heat of the system, i.e

3779958T + 334611.2T = 109.05 x \(10^{6}\)

4114569.2T = 109.05 x \(10^{6}\)

final temperature T = (109.05 x \(10^{6}\))/4114569.2 = 26.5°

The capacitance of two parallel plates increases when a dielectric material is added between them. This is due to the dielectric material's ability to store electric charge and create an electric field between the plates.

The dielectric increases the capacitance because it decreases the electric field, thus allowing more charge to be stored on the plates. The amount of charge stored on the plates is directly proportional to the capacitance of the circuit. Therefore, when a dielectric material is added, the capacitance increases.

Therefore, the final pressure of the gas is 1.52 MPa (megaPascals).

We can use the ideal gas law to solve this problem:

PV = nRT

where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.

First, we need to find the initial number of moles of gas:

n1 = (P1 V1)/(R T1)

= (300 x 10^3 Pa) x (0.3 m^3)/(8.31 J/(mol K) x (20 + 273) K)

= 4.97 mol

where R = 8.31 J/(mol K) is the gas constant.

Next, we can use the fact that the process is isothermal (i.e., at constant temperature) to find the final volume of the gas after it is compressed to a pressure of 800 kN/m^2:

P1 V1 = P2 V2

V2 = (P1 V1)/P2

= (300 x 10^3 Pa) x (0.3 m^3)/(800 x 10^3 Pa)

= 0.1125 m^3

Now we can use the fact that the process is adiabatic (i.e., no heat is exchanged with the surroundings) and that the initial and final volumes are the same to find the final pressure of the gas:

P1 V1^γ = P2 V2^γ

where γ is the adiabatic index (a property of the gas), which depends on the specific gas. For simplicity, we will assume that γ = 1.4, which is a reasonable value for diatomic gases such as nitrogen and oxygen.

P2 = P1 (V1/V2)^γ

= (300 x 10^3 Pa) x (0.3 m^3/0.1125 m^3)^1.4

= 1.52 x 10^6 Pa
