Calculate Heat Flow





Formula

The formula to calculate Heat Flow (HF) is:

\[ HF = \frac{ΔT}{R} \times HTC \]

What is Heat Flow?

Heat flow refers to the transfer of thermal energy from one object or substance to another, often measured in watts (W). The rate of heat flow is influenced by the temperature difference between objects, the thermal resistance (R-value), and the heat transfer coefficient (HTC). Understanding heat flow is critical in various fields, including engineering, construction, and environmental science.

Example Calculation

Let's consider an example:

Using the formula to calculate Heat Flow:

\[ HF = \frac{30}{5} \times 2 = 12 \, \text{W} \]

This shows that with a temperature difference of 30°C, an R-value of 5, and a heat transfer coefficient of 2 W/m²K, the heat flow would be 12 W.
