Answer:

a) the  rate of cooling provided is 18604.8 Btu/h

b) the rate of exergy destruction in the evaporator is 0.46 Btu/Ibm

c) the second-law efficiency of the evaporator is 37.39%

Explanation:

Given that;

Temperature of sink TL = 50°F = 510 R

Temperature at evaporator inlet TI = 10°F = 470 R

mass flow rate m" = 0.08 lbm/s

quality of refrigerant at evaporator inlet x1 = 0.3

quality of refrigerant at evaporator exit x2 = 1.0

T₀ = 77°F = 537 R

h1 = 107.5 Btu/lbm

s1 = 0.2851 Btu/lbm·R,

h2 = 172.1 Btu/ lbm,

s2 = 0.4225 Btu/lbm·R.

a) rate of cooling provided, in Btu/h.

QL = m"( h2 - h1)

we substitute

QL = 0.08( 172.1 - 107.5

= 0.08 × 64.6

= 5.168 Btu/s

we convert to Btu/h

5.168 × 60 × 60

QL = 18604.8 Btu/h

Therefore the  rate of cooling provided is 18604.8 Btu/h

b) The rate of exergy destruction in the evaporator

Entropy generation can be expressed as;

S_gen = m"(s2 - s1) - QL/TL

so we substitute

S_gen = 0.08( 0.4225 -  0.2851  ) - 5.168 / 510

= 0.010992 - 0.01013

S_gen = 0.00086 Btu/ibm.R

now the energy destroyed expressed as;

X_dest = T₀ × S_gen

so

X_dest =  537 × 0.00086

X_dest = 0.46 Btu/Ibm

Therefore the rate of exergy destruction in the evaporator is 0.46 Btu/Ibm

c)  The second-law efficiency of the evaporator.

Energy expended is expressed as;

X_exp = m"(h1 - h2) - m"T₀(s1 - s2)

we substitute

= 0.08( 107.5 - 172.1 ) - [0.08 × 537 ( 0.2851 - 0.4225 )

= -5.168 - [ - 5.9027)

= -5.168 + 5.9027

= 0.7347 Btu/s

Now second law efficiency is expressed as;

nH = 1 - (X_dest / X_esp)

= 1 - ( 0.46 / 0.7347 )

= 1 - 0.6261

= 0.3739

nH = 37.39%

Therefore the second-law efficiency of the evaporator is 37.39%

Answer:

Efficiency is defined as any performance that uses the fewest number of inputs to produce the greatest number of outputs. Simply put, you're efficient if you get more out of less.

Explanation:

The correct answer is Success in control engineering depends on various factors, and all of them are important to achieve a robust and efficient control system. However, out of the given options, the factor that may not solely determine the success of control engineering is accounting for disturbances and uncertainty.

Disturbances and uncertainty are inherent in most control systems, and accounting for them is crucial to ensure the stability and performance of the system. However, other factors such as the process to be controlled, objectives, computing, sensors, and actuators also play significant roles in control engineering. The process to be controlled affects the design of the control system, as different processes may require different control strategies and techniques. Objectives and computing determine the performance metrics of the control system and the algorithms used to achieve them. Sensors and actuators are necessary components of any control system and must be selected and designed appropriately. Therefore, while accounting for disturbances and uncertainty is undoubtedly an essential factor, it is not the only one. The success of control engineering depends on a comprehensive approach that considers all the relevant factors and optimizes their interplay to achieve the desired control performance.

a. The 26th percentile of the software engineering manager salaries is approximately $111,417.

b. The 97.5th percentile of the software engineering manager salaries is approximately $171,417. The z-score for a salary of $170,000 is approximately 2.910, indicating that it is not considered an outlier based on the given standard deviation.

a. The 26th percentile can be found using the Empirical Rule. According to the Empirical Rule, in a mound-shaped and symmetric distribution, approximately 68% of the data falls within one standard deviation of the mean, 95% falls within two standard deviations, and 99.7% falls within three standard deviations. Since we know the mean base salary is $126,417 and the standard deviation is $15,000, we can calculate the value of the 26th percentile as follows:

First, calculate one standard deviation below the mean:

$126,417 - $15,000 = $111,417

Since the distribution is symmetric, the 26th percentile will be the same as the 74th percentile, which is one standard deviation below the mean. Therefore, the 26th percentile is approximately $111,417.

b. The 97.5th percentile can also be determined using the Empirical Rule. In this case, since 99.7% of the data falls within three standard deviations of the mean, we can calculate the value of the 97.5th percentile as follows:

First, calculate three standard deviations above the mean:

$126,417 + (3 * $15,000) = $171,417

Therefore, the 97.5th percentile is approximately $171,417.

c. To find the z-score for a salary of $170,000, we can use the formula:

z = (x - μ) / σ

Where x is the given salary, μ is the mean, and σ is the standard deviation. Plugging in the values:

z = ($170,000 - $126,417) / $15,000 ≈ 2.910

A z-score of 2.910 indicates that the salary of $170,000 is approximately 2.910 standard deviations above the mean. It is not considered an outlier based on the z-score alone. Typically, an outlier is defined as a data point that falls outside a certain range, often determined by a specified number of standard deviations from the mean. In this case, whether $170,000 is considered an outlier would depend on the specific criteria or threshold set for defining outliers.

Answer:

The answer is True

Explanation:

The enq() and deq() methods of the provided unbounded queue implementation are not wait-free, but they are lock-free. The linearization points for enq() are at the atomic operations of tail.getAndIncrement() and items[i].set(x), while for deq(), the linearization point is at the atomic operation of items[i].getAndSet(null).

The enq() method is lock-free because it guarantees that at least one thread will eventually complete its enqueue operation without being blocked indefinitely. However, it is not wait-free because a thread may need to wait for other threads to complete their enqueue operations if the tail index is incremented by multiple threads simultaneously. The linearization point for enq() is the atomic operation tail.getAndIncrement(), which returns the current value of tail and atomically increments it. This ensures that each enq() operation occurs at a specific point in the execution order. Additionally, the atomic operation items[i].set(x) sets the value of the array element at index i, and this is another linearization point for enq().

For deq(), the linearization point is the atomic operation items[i].getAndSet(null), which retrieves the value of the array element at index i and atomically sets it to null. This ensures that each deq() operation occurs at a specific point in the execution order. It's worth noting that the exact order of enq() and deq() operations may be execution-dependent due to the non-blocking nature of the implementation. Different threads may interleave their operations, and the order of enq() and deq() calls may vary. However, the linearization points ensure that the behavior of each individual enq() and deq() operation is well-defined.

=> Also, the density of oil = 930

That is if Pressure, P in B > 18kpa there will surely be a burst.

The height, h the can waste oil be poured into tank A is;

The maximum pressure  = height × acceleration due to gravity × density) + ( acceleration due to gravity × density × height, j).

Three network addresses that would meet the above criteria are:

A network address is a unique identifier for a node or host on a computer network. Network addresses are intended to be unique identifiers throughout the network, while some networks allow for non-unique local, private, or locally governed addresses.

It is to be noted that the above network addresses are chosen based on the requirements that each subnet must have the prefix 223.1.17/24 and must support a certain number of interfaces.

The number of bits borrowed from the host portion of the address to create the subnet prefix (also known as the "subnet mask") is chosen such that each subnet can support the required number of interfaces.

In the case of Subnet 1, the subnet mask /25 borrows 7 bits from the host portion of the address, leaving the subnet with 2⁷ = 128 possible host addresses. Since only 63 interfaces are required, this is sufficient to meet the requirement.

In the case of Subnet 2, the subnet mask /26 borrows 6 bits from the host portion, leaving the subnet with 2⁶ = 64 possible host addresses.

In the case of Subnet 3, the subnet mask /28 borrows 4 bits from the host portion, leaving the subnet with 2⁴ = 16 possible host addresses. Since only 16 interfaces are required, this is adequate to meet the requirement.

Overall, the network addresses provided above satisfy the constraints described in the question and allow each subnet to support the required number of interfaces.
