Answer:

the pressure at a closed valve attached to the tank 10 ft above its bottom is 37.88 psi

Explanation:

Given that;

depth 1 = 71 ft

depth 2 = 10 ft

pressure p = 17 psi = 2448 lb/ft²

depth h = 71 ft - 10 ft = 61 ft

we know that;

p = P_air + yh

where y is the specific weight of ethyl alcohol ( 49.3 lb/ft³ )

so we substitute;

p = 2448 + ( 49.3 × 61 )

= 2448 + 3007.3

= 5455.3 lb/ft³

= 37.88 psi

Therefore, the pressure at a closed valve attached to the tank 10 ft above its bottom is 37.88 psi

Answer:

The velocity at section is approximately 42.2 m/s

Explanation:

For the water flowing through the pipe, we have;

The pressure at section (1), P₁ = 300 kPa

The pressure at section (2), P₂ = 100 kPa

The diameter at section (1), D₁ = 0.1 m

The height of section (1) above section (2), D₂ = 50 m

The velocity at section (1), v₁ = 20 m/s

Let 'v₂' represent the velocity at section (2)

According to Bernoulli's equation, we have;

\(z_1 + \dfrac{P_1}{\rho \cdot g} + \dfrac{v^2_1}{2 \cdot g} = z_2 + \dfrac{P_2}{\rho \cdot g} + \dfrac{v^2_2}{2 \cdot g}\)

Where;

ρ = The density of water = 997 kg/m³

g = The acceleration due to gravity = 9.8 m/s²

z₁ = 50 m

z₂ = The reference = 0 m

By plugging in the values, we have;

\(50 \, m + \dfrac{300 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{(20 \, m/s)^2}{2 \times 9.8 \, m/s^2} = \dfrac{100 \ kPa}{997 \, kg/m^3 \times 9.8 \, m/s^2} + \dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)50 m + 30.704358 m + 20.4081633 m = 10.234786 m + \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

50 m + 30.704358 m + 20.4081633 m - 10.234786 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

90.8777353 m = \(\dfrac{v_2^2}{2 \times 9.8 \, m/s^2}\)

v₂² = 2 × 9.8 m/s² × 90.8777353 m

v₂² = 1,781.20361 m²/s²

v₂ = √(1,781.20361 m²/s²) ≈ 42.204308 m/s

The velocity at section (2), v₂ ≈ 42.2 m/s

The assembly code in 8086 is used to input two characters and print the characters in ascending order based on their ASCII values.

After that, it compares the characters' ASCII values and creates a string of characters starting with the lower ASCII character and ending with the higher ASCII character, containing both characters. The created character sequence is then printed.

To produce the desired result, the assembly code in the 8086 follows a

The code is broken down as follows:

The data section of the programme is where the variables for the input characters, the counter, and the temporary character for comparison are defined.

The first character is requested by the user in the code section, and it is then saved in the variable first_char.

The second character is then requested from the user, which is then saved in the variable second_char.

The lower and upper ASCII characters are then determined by comparing the first_char and second_char's ASCII values. In the lower_char variable, it stores the lower ASCII character, while in the higher_char variable, it stores the higher ASCII letter.

The temporary character (temp_char) is assigned to the lower ASCII character and the counter is initialised by the code.

The code outputs characters from temp_char up to the highest ASCII character (higher_char) using a loop. For each cycle, the temp_char is likewise increased in order to print the subsequent character.

The ret instruction, which hands control back to the operating system, completes the programme.

The assembly code can correctly enter two characters by following these instructions, as well as identify the bottom and upper ASCII characters and print the characters in ascending order according to their ASCII values. If the user types 'H' as the first character and 'B' as the second character in the example given, the code will print the sequence 'BCDEFGH'.

Answer:s

Explanation:s

It's the law. Under New York law, you can get a citation for riding your bike while listening to music using headphones or earbuds in both ears. It is lawful, however, to listen to music with only one earbud keeping the other ear free.

Sensory deprivation. One of the main ways that people alert each other to danger on the road is through sound. Whether it's honking, yelling or ringing a bicycle bell, you're less likely to hear any of these warnings if you're listening to music putting you at higher risk of an accident.

Decreased attention. The more stimuli you have to contend with, the more difficult it is to dedicate your full attention to one particular task. If you get caught up in a song or story you're listening to while cycling, it can increase your distractibility which could have disastrous consequences.

The majority of cycling-related accidents involve a cyclist and a motor vehicle. Not surprisingly, the injuries a cyclist suffers in such collisions tend to be disproportionately serious and often fatal. Therefore, if you're cycling in traffic, foregoing the headphones can prove to be a life-saving decision.

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.

Given that w is a palindrome, the statement "w minus its first character is a palindrome" is generally false. A palindrome is a string that reads the same forwards and backwards. Removing the first character from a palindrome may result in a non-palindromic string, as the symmetry would be disrupted.

A palindrome is a word, phrase, or sequence of characters that reads the same backward as forward. In other words, it remains the same even if read from the opposite direction. Palindromes are often used as exercises to test programming skills and logic, as they require an algorithm to determine if a given word or string of characters is a palindrome or not. Some examples of palindromic words are "racecar", "level", "deified", and "radar". Palindromes can also be longer phrases or sentences, such as "A man, a plan, a canal, Panama!" and "Madam, in Eden, I'm Adam."

When adding an item to an array-based list with an allocation size equal to the list length, a new array is generally allocated with one more than the current length.

What is an array-based list?

Array-based list is a linear data structure that is used to store and access data in contiguous memory locations. It stores data elements that are of the same type, and the memory allocated is static. Therefore, when you add an element to an array, it is necessary to allocate a new memory space to hold the new value added to the existing array.

The size of the array is crucial when appending an item in the array-based list. When the array-based list allocation size is equal to the list length, a new array is generally allocated with one more than the current length. This is to ensure that there is space for the new item to be added without experiencing a memory overflow.

The correct answer is option C, one more than the current length. This is to ensure that the array is large enough to hold the new item, while not wasting too much space in the allocated memory.

B)  0.8897 M^3/ kg

c)  0.7737 m^3/kg

D)  746.542 k

E)  536.017 kj/kg

efficiency = 58% ( approximately )

Explanation:

Given Data :

Gas constant (R) =  0.287 kJ/ kg.K

T1 = 310 k

P1 ( Kpa ) = 100

r = 11.5 ( compression ratio )

rp = 1.95 ( pressure ratio )

A ) specific internal energy at state 1

 = Cv*T1 =  0.718 * 310 = 222.58 kJ / kg

B) Relative specific volume at state 1

= P1*V1 = R*T1 ( ideal gas equation )

V1 = R*T1 / P1 = (0.287* 10^3*310 ) / 100 * 10^3

V1 = 88.97 / 100 = 0.8897 M^3/ kg

C ) relative specific volume at state 2

Applying  r ( compression ratio) = V1 / V2

11.5 = 0.8897 / V2

V2 = 0.8897 / 11.5 = 0.7737 m^3/kg

D) The temperature (k) at state 2

since the process is an Isentropic process we will apply the p-v-t relation

\(\frac{T1}{T2} = (\frac{V1}{V2}^{n-1} ) = (\frac{P2}{P1} )^{\frac{n-1}{n} }\)

hence T2 = \(9^{1.4-1} * 310\) = 2.4082 * 310 = 746.542 k

e) specific internal energy at state 2

= Cv*T2 = 0.718  * 746.542 = 536.017 kj/kg

efficiency = output /input = 390.3511 / 667.5448 ≈ 58%

surface dimensions of  10m * 8m

answer :

a) 640 m^3/hr

b) 1334.66 m^3

Explanation:

a) Determine the flow rate ( m^3/s ) of the filter handle

Va = Q /A\(_{f}\)

where ; Va = filtration rate ( 8.00 m/h ) ,  Q = flow rate of filter handle , A\(_{f}\) = surface area ( 10 m * 8 m  )

Q = 8 * ( 10m * 8m ) = 640 m^3 / hr

b) Determine the volume of water needed for backwashing plus rinsing the filter in each filter cycle

Лf = 0.96  ( production efficiency )

Vb + Vr = 0.04 Vf

∴ Vf  =  ( Vb + Vr ) / 0.04  ------ ( 1 )

next step ; determine the volume of filtered water making use of effective filtration rate

Ref = ( Vf - Vb - Vr ) / A\(_{f}\)T\(_{c}\)

therefore : Vb + Vr = Vf - ( 80 * 52 * 7.7 ) ----  ( 2 )

Input equation 1 into 2

Vb + Vr = ( ( Vb + Vr ) / 0.04  )  - 32032  ---- ( 3 )

Resolve equation 3

hence the Volume of water needed for Backwashing  and rinsing the filter in each filter cycle

= 1334.66 m^3
