11241 - Humidex[edit]

Summary[edit]

This a mathematical simulation problem. The Formula is given in the question. You have to simulate the Formula.

Explanation[edit]

Actually, no explanation needed. Everything is given.Let the three parametres are Humidex,Temperature and Dewpoint. Find out the formula for them.

Humidex

humidex = temperature + h;

h = (0.5555) * (e - 10.0);

e = 6.11 * exp[5417.7530 * ((1/273.16) - (1/( dewpoint + 273.16)))]

Temperature

temperature = humidex - h;

h = (0.5555) * (e - 10.0)

e = 6.11 * exp[5417.7530 * ((1/273.16) - (1/( dewpoint + 273.16)))]

Dewpoint

dewpoint = (1.0/((1.0/273.16) - (log(e/6.11)/5417.7530))) - 273.16;

e = (h/0.5555)+10.0

h = humidex - temperature

now calculate for all possible pairs. You are given any two of the parameters,find the other one.

Gotchas[edit]

Carefully do the calculations.They are complex. Calculate for all possible pairs. TD,DT,DH,HD,TH,HT
