Answer:

In project management this technique is called "Logical Dependency Technique"

Explanation:

A dependency highlights the logical relationship between two or more activities or task to be carried out in project management

There are basically four types of dependencies

1. Start to start

2. Finish to start

3. Start to finish

4. Finish to finish

A heated long cylindrical rod is placed in a cross flow of air at 20°C (1 atm) with velocity of 10 m/s. The rod has a diameter o
postnew [5]

Answer:

Ts = 413.66 K

Explanation:

given data

temperature = 20°C

velocity = 10 m/s

diameter = 5 mm

surface emissivity = 0.95

surrounding temperature = 20°C

heat flux dissipated = 17000 W/m²

to find out

surface temperature

solution

we know that here properties of air at 70°C

k = 0.02881 W/m.K

v = 1.995 ×10^{-5} m²/s

Pr = 0.7177

we find here reynolds no for air flow that is

Re = \frac{\rho V D }{\mu } = \frac{VD}{v}    

Re = \frac{10*0.005}{1.99*10^{-5}}

Re = 2506

now we use churchill and bernstein relation for nusselt no

Nu = \frac{hD}{k} = 0.3 + \frac{0.62 Re6{0.5}Pr^{0.33}}{[1+(0.4/Pr)^{2/3}]^{1/4}} [1+ (\frac{2506}{282000})^{5/8}]^{4/5}

h = \frac{0.02881}{0.005}0.3 + \frac{0.62*2506{0.5}0.7177^{0.33}}{[1+(0.4/0.7177)^{2/3}]^{1/4}} [1+ (\frac{2506}{282000})^{5/8}]^{4/5}

h = 148.3 W/m².K

so

q conv = h∈(Ts- T∞ )

17000 = 148.3 ( 0.95) ( Ts - (20 + 273 ))

Ts = 413.66 K

Explain and show work:
belka [17]

Answer:

  5

Explanation:

The sum of the digits of the number is ...

  (4+1+3)+(4+6+5)+(7+8+9) = 8+15+24 = 47

The sum of those digits is 4+7=11, and those digits sum to 1+1 = 2.

That is, the value of the number mod 9 (or 3) is 2.

The ones digit is odd, so the value of the number mod 2 is 1.

This combination of modulo values tells you the mod 6 result is 5.

_____

<em>Additional comment</em>

We can look at the (mod2, mod3) values of the numbers 0 to 5:

  0 ⇒ (0, 0)

  1 ⇒ (1, 1)

  2 ⇒ (0, 2)

  3 ⇒ (1, 0)

  4 ⇒ (0, 1)

  5 ⇒ (1, 2) . . . . the mod {2, 3} results we have for the number of interest.

This process of adding up the digits repeatedly is referred to as "casting out 9s." The result of it is the modulo 9 value of the number (with 0 mapped to 9). Checking the mod 9 result of arithmetic operations is one quick way to spot certain kinds of errors. It can also be used as part of a divisibility test for 3 or 9.

Write an application named EnterUppercaseLetters that asks the user to type an uppercase letter from the keyboard. If the charac
ozzi

Answer:

The solution code is given below

  1. using System;
  2. using System.Linq;
  3.      
  4. public class Program
  5. {
  6. public static void Main()
  7. {
  8.  string[] letters = {"A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T","U", "V", "W", "X", "Y", "Z"};
  9.  
  10.  Console.WriteLine("Please input a letter: ");
  11.  string input_letter = Console.ReadLine();
  12.  
  13.  if(letters.Contains(input_letter)){
  14.   Console.WriteLine("OK");
  15.  }else{
  16.   Console.WriteLine("Error. Not uppercase letter.");
  17.  }  
  18. }
  19. }

Explanation:

Firstly we import the necessary libraries, System and Linq (Line 1-2).

Next we create a string array to hold all uppercase letters (Line 8).

Next, we prompt user to input a letter using the ReadLine() method (Line 10 - 11)

At last, we define if and else conditions to check if the letters contains the input letter. If so, print ok else print an error message. (Line 13-17)
