Question

Heat is transferred from a hot fluid to a cold one through a plane wall of thickness (δ), surface area (A) and thermal conductivity (k). The thermal resistance is

Options:

A . 1/A (1/h₁ + δ/k + 1/h₂)

B . A (1/h₁ + δ/k + 1/h₂)

C . 1/A (h₁ + δ/k + h₂)

D . A (1/h₁ + δ/k + 1/h₂)

Answer: Option A
Answer: (a).1/A (1/h₁ + δ/k + 1/h₂)
