yaroslaw [1]

Answer:

Here the code is given as follows,

Explanation:

#include <iostream>

#include <iomanip>

using namespace std;

const double CUBIC_CENTIMETERS_IN_ONE_GALLON = 3785.41;

const double CENTIMETERS_IN_ONE_KILOMETER = 100000.00;

double oilSlickArea(double oilThick,

double oilReleasedRate, double spilTimeInHours);

int main()

{

double oilThickness;

double oilReleasedGallonsPerMinute;

int slickDays;

double spillArea = 0.0;

cout << fixed << showpoint << setprecision(8);

cout << "Enter the oil spill rate per minute (in gallons): ";

cin >> oilReleasedGallonsPerMinute;

cout << endl;

cout << "Enter oil thickness on top of the water (in centimeters): ";

cin >> oilThickness;

cout << endl;

cout << "Enter the number of days for which you want to know "

<< "the area covered by the spilled oil: ";

cin >> slickDays;

cout << endl;

cout << "Oil slick area after each day for " << slickDays << "days."

<< endl << endl;

cout << setw(5) << " " << setw(20) << left << "Slick Area in"

<< setw(20) << left << " Volume of Oil in" << endl;

cout << setw(5) << left << "Day " << setw(20) << left << "Square Kilometers"

<< setw(20) << left << " in Gallons" << endl;

for (int i = 1; i <= slickDays; i++)

{

spillArea = spillArea + oilSlickArea(oilThickness,

oilReleasedGallonsPerMinute, 60 * 24);

cout << setw(4) << left << i << " " << setw(12)

<< setprecision(8) << spillArea / (CENTIMETERS_IN_ONE_KILOMETER * CENTIMETERS_IN_ONE_KILOMETER)

<< " " << setprecision(2)

<< right << setw (15) << (oilReleasedGallonsPerMinute * 60 * 24 * i) << endl;

}

return 0;

}

double oilSlickArea(double oilThick,

double oilReleasedRate, double spilTimeInHours)

{

double oilVolumeInGallons;

double oilVolumeInCubicCentimeters;

double spillArea;

oilVolumeInGallons = oilReleasedRate * spilTimeInHours;

oilVolumeInCubicCentimeters = oilVolumeInGallons * CUBIC_CENTIMETERS_IN_ONE_GALLON;

spillArea = oilVolumeInCubicCentimeters / oilThick;

return spillArea;

}
