The Keystone Pipeline has an inside diameter of 36 inches andcarries a flow rate of 590,000 barrels of crude oil per day at 40°C

.If the pipe is new, non-corroded steel, estimate the pumphorsepower required per mile of pipe.Use rho=1.67 slug/ft3 andμ=1.11x10-4 slug/ft*sec for the oil. This pipeline is in a coldenvironment, does it make sense that the oil is so warm?

Answer:

The pump horse power required per mile of pipe  45.22\ hp/mile

Explanation:

The explanation is shown on the  second third and fourth image

It make sense that the temperature of the oil is high even though the pipeline is in a cold environment this is so because where the oil is been tapped from is  way hotter than the temperature of the pipeline environment  because it is closer to the earths crust than the environment of the pipeline

Write a Person class with a constructor that accepts the following details:
Liono4ka [1.6K]

The person class is an illustration of constructors;

In computer programs, constructors are automatically called when the object of a class is created

<h3>The program in C++</h3>

The class and the constructor program written in C++ programming language is as follows:

int main(){

   string fname, lname,dob,idno,mobileno;

   cin>>lname; cin>>fname; cin>>dob;  cin>>idno; cin>>mobileno;

Person c(fname,lname,dob,idno,mobileno);

if(mobileno.length() == 12){

    if(mobileno[3] == '-' && mobileno[7] == '-'){

        cout << "Name: " << c.getfname() << " " << c.getlname() << endl

 << "Date of birth: " << c.getdob() << endl

 << "ID number: " << c.getid() << endl

 << "Mobile: " << c.getmobile() << endl

 << "Age: "<< getAge(dob)<<endl;

 ;

    }

}

The complete program is added as an attachment

Answer:

Output:-

Enter the five digit lottery number

Enter the digit 1 : 23

Enter the digit 2 : 44

Enter the digit 3 : 43

Enter the digit 4 : 66

Enter the digit 5 : 33

YOU LOSS!!

Computer Generated Lottery Number :

|12|38|47|48|49|

Lottery Number Of user:

|23|33|43|44|66|

Number Of digit matched: 0

Code:-

import java.util.Arrays;

import java.util.Random;

import java.util.Scanner;

public class Lottery {

int[] lotteryNumbers = new int[5];

public int[] getLotteryNumbers() {

return lotteryNumbers;

}

Lottery() {

Random randomVal = new Random();

for (int i = 0; i < lotteryNumbers.length; i++) {

lotteryNumbers[i] = randomVal.nextInt((50 - 1) + 1);

}

}

int compare(int[] personLottery) {

int count = 0;

Arrays.sort(lotteryNumbers);

Arrays.sort(personLottery);

for (int i = 0; i < lotteryNumbers.length; i++) {

if (lotteryNumbers[i] == personLottery[i]) {

count++;

}

}

return count;

}

public static void main(String[] args) {

int[] personLotteryNum = new int[5];

int matchNum;

Lottery lnum = new Lottery();

Scanner input = new Scanner(System.in);

System.out.println("Enten the five digit lottery number");

for (int i = 0; i < personLotteryNum.length; i++) {

System.out.println("Enter the digit " + (i + 1) + " :");

personLotteryNum[i] = input.nextInt();

}

matchNum = lnum.compare(personLotteryNum);

if (matchNum == 5)

System.out.println("YOU WIN!!");

else

System.out.println("YOU LOSS!!");

System.out.println("Computer Generated Lottery Number :");

System.out.print("|");

for (int i = 0; i < lnum.getLotteryNumbers().length; i++) {

System.out.print(lnum.getLotteryNumbers()[i] + "|");

}

System.out.println("\n\nLottery Number Of user:");

System.out.print("|");

for (int i = 0; i < personLotteryNum.length; i++) {

System.out.print(personLotteryNum[i] + "|");

}

System.out.println();

System.out.println("Number Of digit matched: " + matchNum);

}

Bulk wind shear is calculated by finding the vector difference between the winds at two different heights. Using the supercell w
ivanzaharov [21]

Answer:

See explaination

Explanation:

2. 0-1 km shear value: taking winds at 1000mb and 850 mb

15 kts south easterly and 50 kts southerly

Vector difference 135/15 and 180/50 will be 170/61 or southerly 61 kts

3. 0-6 km shear value: taking winds at 1000 mb and 500 mb

15 kts south easterly and 40 kts westerly

Vector difference 135/15 and 270/40 will be 281/51 kts
