Layout

The layout is a way of organizing the elements, products, and raw materials in a design. The layout is the representation of information in a structural, logical, descriptive, coherent form.The layout is a mapping of various equipment arrangements, workstations, machinery, plants, and more. It secures the continuous movement of a product quantity along with the quality.

Question

Explain and write legibly

You need to make heat sinks of Ao = 0.02 m² to dissipate heat quickly. You can
use 63 straight pin fins that are.04-m long and 0.01-m in diameter with k= 238
W/m. C that costs $11,999/m³, or you can use 71 straight rectangular fins that
are 0.06-m long, 0.02-m wide and 0.01m thick, with thermal conductivity 179
W/m. C, that costs $8,999/m³. The convection coefficient is 14 W/m². · C in both
cases. Calculate and compare the cost and performance considering the heat
transfer gains of the two options and decide which one you should use to
dissipate heat quickly.
