Explanation:

The Three types of advanced glazing systems:

1. Structural Glazing

2. Unitized Curtain Wall

3. Structural Silicone Glazing

1. Unitized Curtain Wall: Unitized curtain walls are an assembly of pre-fabricated panels that are connected together to form a complete wall system. The panels are typically made of metal, aluminum, fiberglass, or other materials, and they are held together with a structural frame. The panels can be factory-assembled and then shipped to the job site to be installed.

2. Structural Glazing: Structural glazing is a method of attaching glass to a structural frame to create a glazed façade. This type of glazing is often used for large buildings, where the frame is designed to carry the entire weight of the glass. The glass is usually held in place with a silicone sealant and a metal frame that runs the entire length of the wall.

3. Stick System Glazing: Stick system glazing is a type of façade that uses vertical metal supports to hold up the glass panels. The metal supports are known as “sticks” and they can be either attached to the building structure or to the glass panels themselves. The sticks are connected at the top and bottom of each panel using a system of clips and bolts.

When the temperature outside increases from 0°C to 40°C, what happens to the strong steel pins that clamp a 30 m segment of railroad track to the ground at both ends

As the temperature rises from 0°C to 40°C, the steel pins that clamp the 30 m segment of railroad track to the ground at both ends will expand in length. Steel expands when it heats up and contracts when it cools down. As a result, the pins will expand to keep the track in place, avoiding it from moving or becoming unstable at any point.The coefficient of thermal expansion for steel is about 12 x 10^-6 per degree Celsius (°C) or 12 x 10^-6 per Kelvin (K). Therefore, when the temperature rises from 0°C to 40°C, the increase in temperature will result in a lengthening of the steel pins by approximately:12 x 10^-6 x (40°C - 0°C) x 30 m = 0.0144 m or 14.4 mmThe steel pins that clamp the railroad track to the ground will lengthen by 14.4 mm.
When the temperature rises to 40°C, the railroad track will expand due to the increase in temperature. Since it is clamped by strong steel pins at both ends, the pins will experience additional stress and pressure as the track expands.

1 pum = 10^-12 meters

1 ms = 10^-3 seconds

So, 11.8889 pum/ms = (11.8889)(10^-12 meters/10^-3 seconds) = 11.8889 x 10^-9 meters/second = 11.8889 nm/s

1 mm = 10^-3 meters

1 Ms = 10^6 seconds

1 mg = 10^-6 kilograms

So, 0.00984673 mm*Ms/mg = (0.00984673)(10^-3 meters)(10^6 seconds)/(10^-6 kilograms) = 9.84673 x 10^6 meters*seconds/kilogram = 9.84673 Ms*m/kg

The command to move a file in most operating systems is "mv".

What is operating systems?

Operating system (OS) is a set of software programs that manages the hardware and software resources of a computer. It acts as an intermediary between the user and the computer hardware, and provides a platform for other software applications to run on.

An operating system performs basic tasks such as allocating memory, scheduling tasks, managing input and output (I/O) operations, and managing file systems. It also provides a user interface, allowing users to interact with the computer and run applications.

The command to move a selected file to a location on your computer would be "mv [file name] [destination directory path]".

For example, if you have a file named "file.txt" in your current directory and you want to move it to the "documents" directory, the command would be "mv file.txt ~/documents".

The "mv" command is used to move or rename files or directories in Linux or Unix-based operating systems. The first argument is the name of the file you want to move and the second argument is the destination directory path where you want to move the file.

It's important to note that the "mv" command is permanent, so be careful when using it to move files.

Answer: the absolute static pressure in the gas cylinder is 82.23596 kPa

Explanation:

Given that;

patm = 79 kPa, h = 13 in of H₂O,

A sketch of the problem is uploaded along this answer.

Now

pA = patm + 13 in of H₂O ( h × density × g )

pA= 79 + (13 × 0.0254 × 9.8 × 1000/1000)

pA = 82.23596 kPa

the absolute static pressure in the gas cylinder is 82.23596 kPa

The treatment system will operate as the well mixed chamber.

Disinfection rate constant for the UV light, k is 7.80 /s. Number of bacteria in water need to be reduced by 99.9%

Percent reduction of bacteria should be \($(1-10^{0.99}) \times 100 =89.7\%$\)

Volume of the unit chamber is fixed at 2L

Assume the inlet concentration, \($C_0$\) as 1000

The outlet concentration of bacteria, C should be \($1000-\left(1000 \times \frac{89.7}{100}\right)$\)

                                                                                  = 103

The well mixed chamber will then follow a completely mixed flow reactor model.

Compute the time required :

\($t=\frac{1}{k}\left(\frac{C_0}{C}-1\right)$\)

\($t=\frac{1}{7.8}\left(\frac{1000}{103}-1\right)$\)

  = 1.115 s

Flow through the system is    \($\frac{2 \ L}{1.115 \ s}$\)  = 1.79 L/s

The amount of water treated during the 10 hours of sunlight is 1.79 x 10 x 60 x 60 = 64440 L

The incident light should come from the medium with n2 to undergo total internal reflection.

(a) The incident light should come from the medium with n2 to undergo total internal reflection. Total internal reflection occurs when light travels from a medium with a higher refractive index to a medium with a lower refractive index and the angle of incidence exceeds the critical angle. In this case, since n2 is smaller than n1, the light should originate from the medium with n2 to experience total internal reflection at the interface.

(b) The evanescent field is present in the medium with n1. After total internal reflection, the incident light is completely reflected back into the medium with n1, and it does not propagate into the medium with n2. As a result, the evanescent field is confined to the medium with n1.

(c) To calculate the values of kx and kz in the medium where the field is evanescent, we can use the relationship between the wave vector (k) and the refractive index (n) in each medium. The wave vector in the x-direction (kx) and the wave vector in the z-direction (kz) can be expressed as follows:

kx = (w/c) * n * sin(0₁)

kz = [(w/c)^2 * \(n^2\) - \(kx^2\)]

where:

w = angular frequency of the evanescent field

c = speed of light in vacuum

n = refractive index of the medium

0₁ = angle of incidence

Given:

w = 10¹⁵ rad/s

n1 = 4

n2 = 2

0₁ = 80°

Using the above equations, we can calculate the values of kx and kz in the medium with n1:

kx = (10¹⁵ rad/s / 3x10^8 m/s) * 4 * sin(80°)

kz = [(10¹⁵ rad/s / 3x10^8 m/s) * 4^2 - kx]

After substituting the values and performing the calculations, we can determine the specific values of kx and kz in the medium with n1.

The pressure available to push liquid into the pump inlet is typically called the "Net Positive Suction Head" (NPSH).

The NPSH is the difference between the absolute pressure at the pump inlet and the vapor pressure of the liquid being pumped. The NPSH is crucial for proper pump operation, as it ensures that the liquid does not vaporize before entering the pump, causing cavitation and possible damage to the pump.

Steps to calculate the NPSH:
1. Measure the absolute pressure at the pump inlet.
2. Determine the vapor pressure of the liquid being pumped.
3. Subtract the vapor pressure from the absolute pressure to find the NPSH.
