C program.

simple heat transfer via conduction can be determined by the formula H = kA(T2- T1) / X

H = rate of heat transfer in watts k = coefficient of thermal conductivity for the substance A = cross sectional area in m2 T2 and T1 = temperature in kelvin on the two sides of the conductor X = thickness of the conductor in m

For the project you will write a program that consists of a series of functions that allow the user to find an unknown value given the other values. In other words, A could be determined given H,k,T2,T1 and X. Likewise T2 can be found given H,k,A,T1and X.

The thermal conductivities will be stored in an array, and the user prompted for which one they wish. The following substances will be presented as options:

Substance k

Aluminum 205 Asphalt 0.75 Brass 109 Cast iron 58 Concrete 1.7 Fiberglass 0.04 Glass 0.8 Lead 35 Neoprene 0.05 Plywood 0.13 Silver 429 Zinc 116

There will be two milestones to this project. This lets me check that you are on the right track before the final hand in. Be sure that your program is properly documented and commented, poor or non-existent comments will affect your grade. I am not requiring error checking for incorrectly entered values but be sure the program works for all legitimate values. The requirements will be as follows:

Milestone 1: You will hand in:

• - Algorithm

• - Complete list of inputs and outputs

• - Printout of the program skeleton (preprocessor

  directives, variable declarations, main and return, and function prototypes
