Aluminium copper and steel are often used for heat exchangers. Compare the heat transfer rates for these materials given a flat plate of each $200\mathrm{mm}\times 300\mathrm{mm}$ and $25\mathrm{mm}$ thick. The inner and outer temperatures are $110^{?}\mathrm{C}$ and $20^{?}\mathrm{C}$, values for $\mathrm{k}$ can be found in table 1 Table 1 - typical k values Discuss which parameter used in the calculation is the most effective at increasing heat exchange
