Question

Write a program using a collection of functions to solve simple conduction problems using various forms of the formula H = k * A * (T2-T1)/X H = k * A * (T2-T1)/X Temperature on the other side is 274 K. H = 755.0 W T2 = 298 K k = 0.800 W/m-k T1 = 274 K A = 0.120 m^2 X=0.003 m where H is the rate of heat transfer in watts, k is the coefficient of thermal conductivity for the particular substance in watts per meter Kelvin, A is the cross-sectional area in square meters, T1 and T2 are the Kelvin temperatures on the two sides of the conductor, and X is the thickness of the conductor in meters. Define a function for each variable in the formula. For example, function calcH would compute the rate of heat transfer, calcK would figure the coefficient of thermal conductivity, calcA would find the cross-sectional area, and so on. OUTPUT EXAMPLE Respond to the prompts with the data known. For the unknown quantity, enter -999. Rate of heat transfer (watts) : 755.0 Coefficient of thermal conductivity (W/m-K: 0.8 Cross-sectional area of conductor (m^2) : 0.12 Temperature on one side (K) : 298 Temperature on other side (K) : -999 (unknown) Thickness of conductor (m): 0.003
