Lab 3

In 2001 the United States and Canada's meteorological services revised their wind chill calculations.

Two versions of the new calculation are listed below:

where

• T_{C_wchill} is the perceived temperature in degrees Celsius
• T_C is the actual temperature in degrees Celsius, and
• v_k is the wind speed in km/h

and

where

• T_{F_wchill} is the perceived temperature in degrees Fahrenheit
• T_F is the actual temperature in degrees Fahrenheit, and
• v_m is the wind speed in mph

The old wind chill calculation was:

where

• T_{C_wchill_old} is the perceived temperature in degrees Celsius
• T_C is the actual temperature in degrees Celsius
• v_k is the wind speed in km/h, and
• v_r is the reference speed in km/h (typically 6-8)

Create a class shown in the UML diagram below. In addition to performing the calculations described in above you must implement two additional methods that convert from degrees Celsius to degrees Fahrenheit and vice versa. Implement the main method so that your program does the following:

• Asks the user to enter a temperature in degrees Celsius and a wind speed in km/h.
• Displays the temperature in degrees Fahrenheit and wind speed in mph.
• Calculates the perceived temperature using all three wind chill calculations and displays the results of each calculation in degrees Celsius.

For detailed descriptions of each of these methods, see this Javadoc

Complete the sequence diagram below and show it to your instructor before you begin coding.

Upon completion, demonstrate your program to your instructor.
