Static Friction and Kinetic Friction

Recall from the previous chapter that friction is a force that opposes motion, and is around us all the time. Friction allows us to move, which you have discovered if you have ever tried to walk on ice.

There are different types of friction—kinetic and static. Kinetic friction acts on an object in motion, while static friction acts on an object or system at rest. The maximum static friction is usually greater than the kinetic friction between the objects.

Imagine, for example, trying to slide a heavy crate across a concrete floor. You may push harder and harder on the crate and not move it at all. This means that the static friction responds to what you do—it increases to be equal to and in the opposite direction of your push. But if you finally push hard enough, the crate seems to slip suddenly and starts to move. Once in motion, it is easier to keep it in motion than it was to get it started because the kinetic friction force is less than the static friction force. If you were to add mass to the crate, (for example, by placing a box on top of it) you would need to push even harder to get it started and also to keep it moving. If, on the other hand, you oiled the concrete you would find it easier to get the crate started and keep it going.

Figure 5.33 shows how friction occurs at the interface between two objects. Magnifying these surfaces shows that they are rough on the microscopic level. So when you push to get an object moving (in this case, a crate), you must raise the object until it can skip along with just the tips of the surface hitting, break off the points, or do both. The harder the surfaces are pushed together (such as if another box is placed on the crate), the more force is needed to move them.

By defining the truth table,writing Boolean expressions, Implementing the PAL and PAL equations we can Design a 3-Bit comparetor to compare a level of 100 Using PAL.

To design a 3-bit comparator using PAL (Programmable Array Logic), we can follow these steps:

Step 1: Define the truth table:

We need to compare a level of 100 with a 3-bit input. The truth table for the comparator is as follows:

```A2 A1 A0 | X2 X1 X0

-------------------

0  0  0  | 0  0  0

0  0  1  | 0  0  1

0  1  0  | 0  1  1

0  1  1  | 0  1  1

1  0  0  | 1  0  0

1  0  1  | 1  0  0

1  1  0  | 1  0  0

1  1  1  | 1  1  0

```Step 2: Write the Boolean expressions for the output bits (X2, X1, X0):

Based on the truth table, we can write the Boolean expressions for the output bits:

```X2 = A2'

X1 = (A2 A1')' = A2 + A1

X0 = (A2' A1' A0)' = A2 + A1 + A0

```Step 3: Implementing the PAL:

Now, we can use a PAL to implement the comparator using the Boolean expressions derived above. PALs typically consist of an AND array and an OR array.

The AND array will have the inputs A2, A1, and A0 connected to the product terms. The OR array will have the outputs X2, X1, and X0 connected to the sum terms.

The connections for the PAL are as follows:

```Inputs:

---------

A2 -> Product term 1

A1 -> Product term 2

A0 -> Product term 3

Outputs:

---------

X2 -> Sum term 1

X1 -> Sum term 2

X0 -> Sum term 3

```Step 4: Implementing the PAL equations:

Using the connections described above, we can implement the PAL equations:

```Product term 1: A2'

Product term 2: A2 + A1

Product term 3: A2 + A1 + A0

Sum term 1: X2

Sum term 2: X1

Sum term 3: X0

```The above connections and equations represent a 3-bit comparator using a PAL to compare a level of 100.

The wind velocity on the downstream side of the wind turbine is approximately 7.7 m/s (rounded to one decimal place).

To find the wind velocity on the downstream side of the wind turbine, we can use the concept of conservation of mass and energy.

The available kinetic energy of the wind is proportional to the square of the wind velocity. Since the turbine extracts 35% of the available kinetic energy, the remaining energy after the turbine is 65% (100% - 35%).

Let's assume the wind velocity on the downstream side of the turbine is V_d.

According to the conservation of energy:

(1/2) * ρ * A * (V_u^2) * 0.35 = (1/2) * ρ * A * (V_d^2) * 0.65

ρ is the air density (assumed constant)

A is the cross-sectional area of the turbine (assumed constant)

V_u is the wind velocity on the upstream side of the turbine

V_d is the wind velocity on the downstream side of the turbine

Since the air density, cross-sectional area, and turbine efficiency are constant, we can simplify the equation:

V_u^2 * 0.35 = V_d^2 * 0.65

Dividing both sides by 0.35 and rearranging the equation, we get:

V_d^2 = (V_u^2 * 0.35) / 0.65

Taking the square root of both sides, we find:

V_d = sqrt((V_u^2 * 0.35) / 0.65)

Substituting the given value V_u = 9.3 m/s into the equation:

V_d = sqrt((9.3^2 * 0.35) / 0.65) ≈ 7.719 m/s

Thus, the appropriate answer is approximately 7.7 m/s (rounded to one decimal place).

Note that the isentropic efficiency of the compressor is 0.68 and the entropy generation rate in the compressor is 0.119 kW/K.

We can use the following thermodynamic relations to solve this problem:

h2s = h1 + (s2s - s1) (isentropic process)

h2 = h1 + (q - w) (actual process)

ηisentropic = (h2s - h1) / (h2 - h1) = (T2s - T1) / (T2 - T1)

where h is the enthalpy, s is the entropy, q is the heat added, w is the work done, and ηisentropic is the isentropic efficiency.

To calculate the entropy generation rate (Sgen) in the compressor, we can use the following relation:

Sgen = q/Tc - q/Th

where Tc is the average surface temperature of the compressor and Th is the temperature of the compressed fluid at the compressor outlet.

Given:

P1 = 140 kPa

T1 = -10°C = 263.15 K

P2 = 1200 kPa

T2 = 50°C = 323.15 K

W = 150 kW

Qloss = 40 kW

Tc = 20°C = 293.15 K

Using the refrigerant tables, we can determine the enthalpies and entropies at the compressor inlet and outlet:

At the compressor inlet:

h1 = 187.67 kJ/kg

s1 = 0.9396 kJ/kg·K

At the compressor outlet:

h2 = 307.23 kJ/kg

s2 = 1.1058 kJ/kg·K

To calculate h2s, we assume an isentropic process, so s2s = s1 and P2s = P1. Using the refrigerant tables, we find:

h2s = 259.62 kJ/kg

a) The isentropic efficiency can be calculated as:

ηisentropic = (h2s - h1) / (h2 - h1) = (259.62 - 187.67) / (307.23 - 187.67) = 0.661 or 66.1%

b) The heat added to the compressor can be calculated as:

q = W + Qloss = 150 + 40 = 190 kW

The temperature at the compressor outlet can be determined from the refrigerant tables at P2 = 1200 kPa:

h2f = 210.13 kJ/kg

The final temperature can be calculated as:

T2f = T1 + (h2f - h1) / cp = 59.43°C

The entropy generation rate can be calculated as:

Sgen = q/Tc - q/Th = q(1/Tc - 1/Th) = 190(1/293.15 - 1/332.58) = 1.57 kW/K

The term that matches the definition is "high-level programming language."

In a high-level programming language, the instructions and syntax are designed to be close to everyday English, making it easier for programmers to read, write, and understand the code. High-level programming languages abstract away many low-level details and complexities of computer hardware, providing a more intuitive and human-friendly approach to programming.

These languages utilize a vocabulary and syntax that resemble natural language, with keywords and constructs that align with common concepts and actions.

For example, high-level languages may use keywords such as "if," "while," and "for" to represent conditional statements, loops, and iteration. Variables and functions are often named using descriptive words or phrases, allowing for more expressive and self-explanatory code.

By using a high-level programming language, developers can focus on the logical aspects of their programs rather than getting lost in intricate machine-level details. This abstraction enables faster development, better code readability, and increased productivity.

Examples of high-level programming languages include Python, Java, C++, and JavaScript. These languages provide extensive libraries, frameworks, and tools that simplify complex tasks and provide a wide range of functionalities. The use of natural language-like syntax in these languages enhances the programmer's ability to communicate intentions and ideas effectively.

In contrast, low-level programming languages, such as assembly or machine code, use instructions that directly correspond to the underlying hardware architecture, offering more control but requiring a deep understanding of computer internals. High-level languages bridge this gap and make programming more accessible and user-friendly for developers.
