Question

used to make the fins, 2) the number of fins in the array, and 3) the heat transfer rate from the array. Solution: 1) To determine the material used to make the fins, we need to calculate the thermal conductivity, k, of the material. The thermal conductivity can be calculated using the formula: k = (h * Ab,c) / (Af * εf) Substituting the given values: k = (100 W/K∙m * 0.5 cm2) / (20 cm2 * 32) 2) To find the number of fins in the array, we can use the formula: N = At / Af Substituting the given values: N = 220 cm2 / 20 cm2 3) To calculate the heat transfer rate from the array, we can use the formula: Q = N * h * Af * θb Substituting the given values: Q = N * 100 W/K∙m * 20 cm2 * 50 K

          used to make the fins, 2) the number of fins in the array, and 3) the heat transfer rate from the array.

Solution:

1) To determine the material used to make the fins, we need to calculate the thermal conductivity, k, of the material. The thermal conductivity can be calculated using the formula:

k = (h * Ab,c) / (Af * εf)

Substituting the given values:

k = (100 W/K∙m * 0.5 cm2) / (20 cm2 * 32)

2) To find the number of fins in the array, we can use the formula:

N = At / Af

Substituting the given values:

N = 220 cm2 / 20 cm2

3) To calculate the heat transfer rate from the array, we can use the formula:

Q = N * h * Af * θb

Substituting the given values:

Q = N * 100 W/K∙m * 20 cm2 * 50 K
