North American wind chill index In November 2001 the National Weather Service implemented the new wind chill index, used by the U.S. and Canadian weather services, which is determined by iterating a model of skin temperature under various wind speeds and temperatures. The model used standard engineering correlations of wind speed and heat transfer rate. Heat transfer was calculated for a bare face in wind, facing the wind, while walking into it at 1.4 meters per second (3.1 mph). The model corrects the officially measured wind speed to the wind speed at face height, assuming the person is in an open field. The results of this model may be approximated, to within one degree, from the equivalent formula in US customary units: T_wc = 35.74 + 0.6215T_a - 35.75V^0.16 + 0.4275T_a V^016 where T_ux. and T_a are measured in degree F, and v in mph. T_a represents actual temperature and V is wind speed, so, for example, if the actual temperature is 22 degrees F and the wind speed is 15 mph, the wind chill would be 8.8. Write a program which varies wind speed from 5 to 45 by 5 and temperature from -5 to 50 by 5 and displays a table of windchill values similar to
