SUMMARY
The convection heat transfer coefficient (h) is not a constant and varies with temperature, particularly in real-world applications where flow conditions change. In scenarios with constant flow, h can be treated as constant, but this is not universally applicable. The discussion highlights the importance of understanding the relationship between temperature and h, emphasizing that variations occur due to changes in fluid properties and flow dynamics.
