Question

In cold weather, meteorologists report an index called the windchill factor, that takes into account the wind speed and the temperature. The index provides a measure of the chilling effect of wind at a given air temperature. Windchill may be approximated by the formula:

where

v = wind speed in m/sec

t = temperature in degrees Celsius: t <= 10

W= windchill index (in degrees Celsius)

Write a function that returns the windchill index. Your code should ensure that the restriction on the temperature is not violated. Look up some weather reports in back issues of a newspaper in your university library and compare the windchill index you calculate with the result reported in the newspaper.

Explanation / Answer

#include<iostream>
using namespace std;

//Function to compute the windchill
double computeWindChillFactor(double v,double t)
{
   //To check whether maximum temperature condition vilates
   if(t>10)
   {
       cout<<"The temperature is greater than allowed limit 10"<<endl;
       return 0;
   }

   //compute and return the windchill factor
return 13.12 + (0.6215*t) - (11.37*v*0.16) + (0.3965*t*v*0.16);
}

int main(){
  
double result= computeWindChillFactor(10,5);
if(result==0)
   cout<<"Error in temperature"<<endl;
else
   cout<<"The windChill factore is " <<result<<endl;

   system("pause");
return 0;
}
