Answer:

The answer is " \Delta p = f(V1, p, V2, d, D, L)"

Explanation:

Please find the complete question in the attached file.

Its change in temperature in pipes depends on rate heads and loss in pipes owing to pipe flow, contractual loss, etc.

Answer:

Without Recursives

// Program is written using C++

// Comments are used for explanatory purpose

int main()

{

// Declare integer number, n

int n;

cout<<"Enter number of starts to print"

cin>>n;

// Iterate through to print * pattern

for(i=n; i>0;i--)

{

for(j=n; i>j-1;j--)

{

cout<<"*";

}

cout<"\n";

}

for(i=0; i< n; i++)

{

for(j=0;j<=i;j++)

{

cout<<"*";;

}

cout<"\n";

}

return 0;

}

Using Recursive

#include <iostream>

using namespace std;

void printStars(int lines);

int main()

{

// prompt the user to enter a number

int lines;

cin>> lines;

printStars(int lines);

return 0;

}

void printStars(int lines)

{

if (lines < 1)

return;

// to print the stars of a particular row

if (i <= lines)

{

cout << "* ";

// recursively print rest of the stars

// of the row

printPatternRecur(lines, i + 1);

}

else

{

// change line

cout << endl;

// print stars

printPatternRecur(lines-1, 1);

}

}
