Answer:

0,5 bags

Total number of bags = 0.5 +  4 = 4.5 bags or 5 bags

Explanation:

Convert 15cm to meters  = 15/100 = 0.15m

Flow rate Q = Area x velocity

= π d x v

= π (0.15) x 1

= 0.4712

A = Q/v = 0.4712/ 0.05

=<u> 9.435 m^2</u>

<u></u>

The net number of bags =  A/π dh

= 9.425/π (0.15)(5)

= <u>4 bags </u>

<u></u>

Requirement that 1/8 of the bags are off-line for cleaning

= Net number of bags / 8

= 4/8

= <u>0.5 bag or 1bag</u>

<u></u>

<u>Total number of bags </u>

<u>= 4bags + 1bag </u>

<u>= 5bags </u>

<u></u>

The variation of the pressure of a fluid with density at constant temperature is known as the _____.
qaws [65]

The variation of the pressure of a fluid with density at constant temperature is known as the coefficient of compressibility.

<h3>What is a compressor?</h3>

A compressor can be defined as a mechanical device that is designed and developed to provide power to refrigerators, air conditioners, and other heating or cooling mechanical devices (engines), especially by increasing the pressure on air or other applicable gases.

In an isothermal process, the coefficient of compressibility is also known as isothermal compressibility or compressibility and it refers to a measure of the variation of the pressure and relative volume of a fluid with density at constant temperature.

Write a function called largest3 which takes 3 numbers as parameters and returns the largest of the 3. Write a program which tak
tamaranim1 [39]

Answer:

The solution code is written in Python.

  1. def largest3(num1, num2, num3):
  2.    largest = num1
  3.    if(largest < num2):
  4.        largest = num2
  5.    
  6.    if(largest < num3):
  7.        largest = num3
  8.    
  9.    return largest
  10. first_num = int(input("Enter first number: "))
  11. second_num = int(input("Enter second number: "))
  12. third_num = int(input("Enter third number: "))
  13. largest_number = largest3(first_num, second_num, third_num)
  14. print("The largest number is " + str(largest_number))

Explanation:

<u>Create function largest3</u>

  • Firstly, we can create a function <em>largest3 </em>which take 3 numbers (<em>num1, num2, num3</em>) as input. (Line 1).
  • Please note Python uses keyword <em>def </em>to denote a function. The code from Line 2 - 10 are function body of <em>largest3</em>.
  • Within the function body, create a variable,<em> largest</em>, to store the largest number. In the first beginning, just tentatively assign<em> num1 </em>to<em> largest</em>. (Line 2)
  • Next, proceed to check if the current "<em>largest</em>" value smaller than the<em> num2 </em>(Line 4). If so, replace the original value of largest variable with <em>num2</em> (Line 5).
  • Repeat the similar comparison procedure to<em> </em><em>num3</em> (Line 7-8)
  • At the end, return the final value of "<em>largest</em>" as output

<u>Get User Input</u>

  • Prompt use input for three numbers (Line 13 -15) using Python built-in <em>input</em> function.
  • Please note the input parts of codes is done outside of the function <em>largest3</em>.

<u>Call function to get largest number and display</u>

  • We can simply call the function<em> largest </em>by writing the function name <em>largest</em> and passing the three user input into the parenthesis as arguments. (Line 17)
  • The function <em>largest </em>will operate on the three arguments and return the output to the variable <em>largest_number</em>.
  • Lastly, print the output using Python built-in <em>print</em> function. (Line 18)
  • Please note the output parts of codes is also done outside of the function<em> largest3</em>.

A minivan starts from rest on the road whose constant radius of curvature is 40 meters and whose bank angel is 10 degrees. the m
zimovet [89]

Based on the calculations, the magnitude (a) of it's total acceleration is equal to 2.71 m/s².

<u>Given the following data:</u>

  • Angle of inclination = 10°.
  • Radius of curvature, r = 40 meters.
  • Acceleration of the minivan, A = 1.8 m/s².
  • Initial velocity, u = 0 m/s (since it's starting from rest).
  • Time, t = 5 seconds.

<h3>How to determine the magnitude (a) of it's total acceleration?</h3>

First of all, we would determine the final velocity of the minivan by applying the first equation of motion as follows:

V = u + at

V = 0 + 1.8 × 5

V = 9 m/s.

Next, we would calculate the centripetal acceleration of this minivan:

Ac = V²/r

Ac = 9²/40

Ac = 2.025 m/s².

Now, we can determine the magnitude (a) of it's total acceleration:

a = √(Ac² + A²)

a = √(2.025² + 1.8²)

a = 2.71 m/s².

Tech A says you can find the typical angle of a V-block engine by dividing the number of cylinders by 720
Lady_Fox [76]

Answer:

Tech A is correct

Explanation:

Tech A is right as its V- angle is identified by splitting the No by 720 °. Of the piston at the edge of the piston.

Tech B is incorrect, as the V-Angle will be 720/10 = 72 for the V-10 motor, and he says 60 °.
