= (0.003129 * ((temperature in °C)^2)) + (0.0011 * (temperature)) + 1.668

 

water requirement in quarts per day at light work levels =

= (0.005964 * ((temperature in °C)^2)) + (0.00818 * (temperature)) + 1.655

 

water requirement in quarts per day at light to moderate work levels =

= (0.007479 * ((temperature in °C)^2)) - (0.00694 * (temperature)) + 2.505

 

water requirement in quarts per day at moderate work levels =

= (0.009479 * ((temperature in °C)^2)) - (0.03865 * (temperature)) + 3.963

 

water requirement in quarts per day at hard work levels =

= (0.01126 * ((temperature in °C)^2)) - (0.04301 * (temperature)) + 5.4
